▼ Marine bivalves are globally recognized as ecologically and commercially valuable species and, for over a century, researchers have been studying their feeding, digestion and other related physiological processes. These studies have shown that marine bivalves have complex feeding and particle processing behaviors to maximize growth in dynamic environmental conditions. Additionally, these studies have provided insights into the ecological roles that these animals can play in coastal waters. Suspension-feeding bivalves are commonly regarded as providing key ecosystem services through their feeding activities that improve water quality and clarity. However, marine bivalves are currently under threat from a variety of anthropogenic effects and there is concern about their future health under these new stresses. Here I examined several unexplored aspects of adult and larval bivalve feeding physiology in an attempt to better understand environmental effects on their feeding activity and ecosystem services. In Chapter 2, my co-authors and I examined the ecological feeding physiology of native Olympia oysters Ostrea lurida by determining their feeding and particle processing behavior in response to the effects of temperature, salinity, and total particulate matter. We examined and compared these processes to those of the non-native yet dominant commercial oyster species, the Pacific oyster Crassostrea gigas. From these studies, we describe the first modern detailed feeding behavior of O. lurida. We found that, although markedly different in laboratory studies, in situ feeding rates were similar between these species seasonally. We concluded that bivalve filtration services are likely to be greater with the emergence of C. gigas as the now dominant species in many PNW estuaries and seasonally much greater than the services historically contributed by O. lurida. In Chapters 3, my co-authors and I examined the particle processing behavior of bivalve larvae. This study was novel in that it utilized methods of our own design to examine the rarely evaluated post-oral particle processing behavior of larvae that historically has been difficult to measure. Additionally, it represented the first attempt at modeling larval guts as chemical reactors to provide insights into their digestive strategies. In Chapter 4, we again applied these novel techniques to evaluate the effects of ocean acidification on ingestion rates and particle processing of larvae of the California mussel Mytilus californianus. These data were applied to a simple larval energy budget to understand how impacts of ocean acidification on initial larval development may affect their subsequent development rates. The outcomes of these experiments provide useful information on feeding and particle processing activities of the adult and larval life stages of marine bivalves and the effects of environmental factors, such as ocean acidification.

▼ Laternula elliptica are large bivalves found in high densities in soft sediments in coastal regions of the Southern Ocean. L. elliptica form an important part of the ecosystem, due to significant sediment stabilisation and deposition. Despite the important role L. elliptica play in their environment, little is known about how projected ocean change will impact future populations of this species. Invertebrate larvae are considerably more sensitive to environmental stressors than juveniles and adults, and increases in mortality and minor reductions in dispersal could significantly reduce future population sizes. In a rapidly changing climate, some of the greatest changes are expected at high latitudes. The greatest rates of warming of surface waters are occurring in the Southern Ocean. Additionally, undersaturation of aragonite due to ocean acidification is expected to affect these waters within decades. Calcifying organisms such as molluscs may be particularly sensitive to reduced pH and saturation states associated with ocean acidification. However, information on larval responses to these stressors in Antarctic species is limited. The larvae of L. elliptica are large and lecithotrophic. Maternally provided energy reserves sustain development until the completion of metamorphosis. While large reserves may support long development times and extended encapsulation, they are finite and cannot be replenished. Any stress during larval development could increase metabolic costs and deplete reserves, preventing metamorphosis. These stressors may also impact the calcification process and shell structures, resulting in weaker larvae at settlement that are more vulnerable to injury. Small reductions in larval survival could limit recruitment and population growth may decline. Various responses to ocean acidification (OA) and warming were studied in the larvae of L. elliptica. Larvae were raised under control pH and temperatures (~8.00 and - 1.7°C, respectively) and conditions representing projections for the Antarctic by the end of the century and 2300 (pH 7.80, 7.65 and -0.5, +0.5 and +1.5°C), both individually and in combination. The effect of these stressors on fertilisation rates, development timing and rates of abnormalities at various life stages were examined. Furthermore, SEM analysis determined the impacts of OA and warming on larval shell growth and morphology. Respiration rates and lipid reserves in developing larvae were also determined. Information on OA and temperature responses in Antarctic larvae is limited, and this is the first study on the effects of these stressors in Antarctic bivalves. Elevated temperatures largely improved development, increased early fertilisation rates, and accelerated development through all larval stages and larvae reached competency 5 d ahead of larvae at the control temperature. This would allow for faster settlement, significantly reducing time spent in more vulnerable development stages. Elevated temperatures also improved calcification in later D-stage larvae increasing shell… Advisors/Committee Members: Ken, Ryan, Vonda, Cummings.

▼ Proteases são enzimas que catalisam a hidrólise de ligações peptídicas de maneira seletiva, o que resulta na degradação de proteínas. Essas enzimas são amplamente utilizadas na indústria nas indústrias química, farmacêutica e de alimentos, por exemplo, por apresentarem diversas aplicações biotecnológicas. Na sua estrutura nativa, proteínas de reserva geralmente não apresentam nenhuma atividade antimicrobiana, mas quando degradadas por proteases podem liberar peptídeos bioativos com ação antimicrobiana. Os objetivos da presente dissertação foram purificar e caracterizar uma protease a partir da massa visceral do mexilhão Mytella charruana (denominada MycP, do inglês M. charruana protease) e avaliar sua capacidade de hidrolisar caseína de leite e gerar peptídeos antimicrobianos. A massa visceral de M. charruana foi homogeneizada com Tris-HCl 0,1M pH 8,0 e, após centrifugação, o extrato foi avaliado quanto à atividade proteolítica total. O efeito de inibidores de protease foi avaliado. MycP foi isolada através de cromatografia de gel filtração (Sephadex G-75) seguida de cromatografia de troca iônica (DEAE-Sephadex A25). A protease foi submetida à focalização isoelétrica e SDS-PAGE e avaliada quanto à atividade tripsina-símile. O efeito do pH e temperatura na atividade tripsina-símile foi determinado. MycP foi utilizada para realizar a hidrólise da caseína e o hidrolisado foi avaliado quanto à atividade antibacteriana contra Escherichia coli, Bacillus subtilis, Klebsiella pneumoniae e Micrococcus luteus, e atividade antifúngica contra Candida albicans, Candida tropicalis e Candida krusei. O extrato da massa visceral teve sua atividade proteolítica inibida em 55%, 59% e 24%, respectivamente, indicando a presença de aspártico, serino e metalo proteases. MycP apresentou pI 4,1 e uma única banda polipeptídica de 83,1 kDa em SDS-PAGE. MycP apresentou atividade semelhante à tripsina com temperatura ótima de 40ºC. Esta atividade foi estável numa ampla gama de pH (3,0-9,0). O Km relativo à atividade tripsina-símile de MycP foi 4,28±0,34 mM de BApNA e a Vmáx foi 0,056 ± 0,001 nmol de BApNA/min. MycP foi capaz de promover a hidrólise de caseína e o hidrolisado foi capaz de inibir o crescimento de Escherichia coli, Micrococcus luteus, Bacillus subtilis e Klebsiella pneumoniae com MIC de 5,0 μg/mL para todas essas bactérias. Não foi detectada atividade antifúngica contra as espécies de Candida testadas. Em conclusão, a massa visceral de M. charruana contém uma protease com atividade tripsina-símile capaz de gerar peptídeos com efeito bacteriostático derivados da hidrólise da caseína.

▼ This study focused on (1) Green mussel (Perna viridis) growth determination and harvestable area models and (2) optimisation model for cockle (Anadara granosa) culture in Pattani Bay, Thailand. The main objectives of this study are: (a) Development of a mussel growth determination model, (b) Development of a harvestable area model for mussels, (c) Development of a suitable area model for cockle farming. Four main, geo-referenced input data sets were developed, comprising (1) water quality parameters, (2) sediment quality parameters, (3) empirical mussel growth and (4) secondary data related to the target species and the bay ecology including satellite images of study area were employed. Data on twelve water quality parameters and four sediment parameters were collected in the field between June 2009 and February 2010 while mussel growth data was collected between June and September 2009. Different combinations of data from these groups were managed and manipulated within the IDRISI™ environment to address the different study objectives and to formulate databases, analyse data, and develop and illustrate spatial models. The main output models of the study were (1) mussel growth determination models, (2) suitable mussel culture and harvestable area models and (3) models for optimisation of suitable cockle culture area. Principal Component Analysis (PCA) and Multiple Linear Regressions (MLR) were employed to determine optimised conditions for mussel growth determination. The main determinants for mussel growth were particulate organic matter (POM), chlorophyll-a and salinity. All three together can predict 85.2% of mussel growth while chlorophyll-a and salinity could predict 84.9% and salinity alone could predict 83.4% of observed mussel growth. The optimum suitable area for mussel farming was estimated using overlaying techniques to combine three main components comprising salinity, water depth and shipping route. Of the 58 km2 of the total water space in the bay, a potential optimised area for mussel farming of 13 km2 was found. The remaining area was limited for culture due to low salinity, inadequate water depth and presence of shipping routes. Based on the empirical growth function of mussel, the mussel harvestable areas were projected and illustrated periodically. The harvest period of mussel within the potential culture site extends over 2 months. The spatial analysis showed that <50% of the current mussel culture operations within the bay are located within the optimal area and the models also identified > 12.5 km2 that could be developed further. The suitable cockle farming area was estimated using a Multi-Criteria Evaluation (MCE) approach based on sediment and water factors reclassified as a fuzzy data set. The maximum water surface area suitable for cockle culture was 48 km2, but this decreased to around 13 km2 when water depth, water current and sediment suitability were taken into account. The overall suitable cockle culture area was found in the middle part of the bay and approximately 75%…

L’extraction de l’arche noire (AN) Anadara tuberculosa est une des activités de pêche artisanale ancestrales des mangroves de la côte ouest d’Amérique Latine et son commerce soutient l’économie de milliers de familles. La conservation de ce bivalve emblématique des mangroves est menacée par la surexploitation des populations naturelles. Les mesures classiques de préservation de l’espèce se sont révélées inefficaces pour enrayer le déclin des populations. Ce travail de thèse propose la production de naissains en conditions artificielles d’écloserie, au Pérou, à des fins de repeuplement à l’issue d’un processus de « domestication » de ce bivalve sauvage. Nous avons 1) analysé la structure génétique des populations d’AN Sud-américaines, 2) évalué l’effet de différentes salinités sur la réponse physiologique de l’AN, 3) établi une stratégie de production de naissains SPF (Specific Pathogen Free) à partir de reproducteurs caractérisés génétiquement et provenant du Sanctuaire National des Mangroves de Tumbes. Ce travail constitue un modèle pour les futures stratégies de production et de repeuplement des stocks d’autres espèces vulnérables.

The extraction of the Black Ark (BA) Anadara tuberculosa is one of the ancestral artisanal fishing activities of Latin America West Coast mangroves and its trade supports the economy of thousands of families. The conservation of this emblematic bivalve of mangroves is threatened by the overexploitation of natural populations. Conventional conservation measures have proved to be ineffective in halting the decline of populations. This thesis work proposes spats production in artificial conditions of hatchery, in Peru, in order to restock after a process of “domestication” of this wild bivalve. We have 1) analyzed the genetic structure of some South American BA populations, 2) evaluated the effect of different salinities on the physiological response of the BA, 3) produced in hatchery specific pathogen free (SPF) spats from geneticallycharacterized broodstocks of the National Sanctuary of Mangroves of Tumbes. This work is a model for future strategies for the production and restocking of stocks of other vulnerable species.

▼ O estuário do rio Formoso localiza-se no litoral sul do estado de Pernambuco (8º 39 - 8º 42 S e 35º 10 35º 05 W) e está inserido em uma área de proteção ambiental, denominada APA de Guadalupe. Este ecossistema desempenha um importante papel socioeconômico para a comunidade local, além de possuir uma grande diversidade ecológica. Os impactos produzidos pelos despejos de efluentes hospitalares e domésticos, aumento do trafego de embarcações motorizadas, carreamento de agrotóxicos de plantações das proximidades e uso destes para a pesca predatória, provocam um acentuado desequilíbrio no estuário, refletindo diretamente na população local, pela introdução de metais-traço nas áreas costeira e estuarina. Baseado nestas prerrogativas, o presente estudo visou a determinação das concentrações de metais-traço (zinco, selênio, arsênio, alumínio, ferro, manganês, chumbo e cromo) no sedimento superficial e em duas espécies de moluscos filtradores (Crassostrea rhizophorae e Mytella charruana), objetivando basicamente avaliar o grau de contaminação do estuário e fornecer indicadores para o estabelecimento de um futuro monitoramento ambiental da área. Amostras de sedimentos superficiais foram coletadas em 04 estações ao longo do estuário, durante os períodos seco e chuvoso do ano de 2009 nas margens direita e esquerda do estuário do rio Formoso. A profundidade do material coletado esteve compreendida entre 0 e 10 cm, onde as amostras foram colhidas durante as baixa-mares. Amostras do material biológico foram coletadas em bancos naturais do estuário localizados próximos à estação 2. Os parâmetros hidrológicos foram coletados nas mesmas estações do sedimento, na parte mais profunda da área. Os resultados obtidos indicaram elevadas concentrações de zinco, arsênio, ferro, manganês, chumbo e cromo nos sedimentos e arsênio, ferro e manganês nos moluscos bivalves. Para análise e quantificação dos metais nos sedimentos e moluscos, foram realizadas digestões ácidas próprias para cada matriz e utilizado o Espectrômetro de Emissão Ótica em Plasma Indutivamente Acoplado (ICP-OES). Os dados produzidos indicaram contaminação das matrizes utilizadas na pesquisa, onde os resultados obtidos foram comparados aos valores de referência das agências ambientais nacionais e internacionais Advisors/Committee Members: José de Macêdo, Silvio (advisor).

▼ This dissertation investigated the ‘disco’ clam Ctenoides ales (Limidae), which is the only bivalve to have a behaviorally-mediated flashing display. Topics covered include (i) mechanisms, ultrastructure and movement that produce the flashing, (ii) the fitness value (function) of the flashing, (iii) the clams’ sensory abilities and vision, and (iv) the clams’ ecology, distribution and habitat. The flashing occurs on the clams’ mantle lip. Electron microscopy revealed two distinct tissue sides; one highly scattering side that contains dense aggregations of spheres composed of silica (white), and one highly absorbing side that does not (red). High-speed video confirmed that the two sides alternate rapidly, creating the appearance of flashing. Optical modeling suggested that the sphere’s diameter is nearly optimal for scattering light, especially at shorter wavelengths, which predominate in the ocean. This simple mechanism produces a striking optical effect. Three potential hypotheses for the fitness value of the flashing were investigated; conspecific attraction, prey luring, and/or predator deterrence. The lack of movement toward other C. ales when given visual cues in behavioral trials, as well as the clams’ inability to resolve flashing in other C. ales suggested conspecific attraction was not the function of the flashing. The lack of significant differences in prey abundance in experiments testing flashing versus non-flashing clams suggested prey luring was also not the function of the flashing. Predator deterrence is considered a possible function of the flashing due to (i) sulfur presence in the clam’s tissues, (ii) behavioral responses by predators during feeding trials as well as tissue preferences that suggest potential distastefulness, and (iii) the clams’ increase in flash rate when exposed to predators in the lab and the field. The presence of photosensitive pigments (rhodopsin, tubulin and retinochrome) was suggested from immunohistochemistry results in the ~40 eyes of C. ales in collaboration with A. Nahm-Kingston (University of Maryland Baltimore County). Transmission electron microscopy done in collaboration with R. Dubielzig, L. Teixeira, and C. Schobert (University of Iowa Veterinary School) confirmed that the morphology of the eye was inconsistent with image formation or the ability to resolve flashing in conspecifics. Therefore, the visual capability of C. ales is most likely used for predator detection. The clams’ distribution, depth, main habitats, projected sex ratios, movement based on size (sex) and sphere properties with depth were identified through SCUBA research at four field sites. The clams are found throughout the Indo-Pacific, from depths 3m to ≥50m. Their movement doesn’t vary with sex, and they exhibit a clumped distribution seemingly skewed towards males, which compounds their vulnerability in aquaria collections and highlights the need to determine their conservation status.

▼ In Brazil, various species of bivalves presente in intertidal zones with different levels of salinity, have been widely collected by coastal communities. Considering this context, in chapter 1, a survey of the aspects of the artisanal extraction activity for the mollusk Anomalocardia brasiliana (GMELIN, 1791) was carried out, noting the aspects relative to the socio-environmental perception of the women shellfishers associated to the colony of fishers Z-13 in the municipality of Senador Georgino Avelino/RN, Brazil. The methodology used was based on interviews using a structured questionnaire, applied to 41 women shellfishers. In the results, it became clear that the extraction activity is a source of income and the shellfish are used to compliment the family diet of this group. In Chapter 2, the reduction of A. brasiliana in natural stocks during rainy periods was investigated, as reported by the women shellfishers during the interviews, and could be related to the salinity of the water in the environment. In this context, an experiment was carried out in the laboratory, where the mollusks were subjected to the salinities: 5 ppt, 15 ppt, 25 ppt, 35 ppt, 45 ppt, 55 ppt and 65 ppt, with an experimental design consisted of 7 treatments with 7 repetitions distributed in 49 experimental units with 12 individuals in each experimental unit (RODRIGUES, 2015, adapted). The animals were fed with dehydrated microalgae (Spirulina spp). Among the results obtained, a greater survival of these animals was shown in the salinities of 25 ppt and 35 ppt, noting that the oscillation in the abundance of these animals throughout the year can be directly related to the salinity found in the environment. The present study showed the relevance of A. brasiliana extraction for the women shellfishers of the municipality and the survival of this mollusk at different salinities, especially in the salinities 25 ppt and 35 ppt.

Les écosystèmes côtiers sont parmi les plus vulnérables aux changements globaux actuels, qui entraînent notamment une augmentation de la température de l'eau, ainsi que de la fréquence des épisodes hypoxiques. La coquille Saint-Jacques, Pecten maximus, est une espèce subtidale évoluant à des profondeurs de 2 à 210 m. Malgré son intérêt commercial et un intérêt écologique majeur, cette espèce n'a fait l'objet que de peu d'études au niveau moléculaire. L'objectif de cette thèse était de caractériser les mécanismes moléculaires régissant l'acclimatation de cette espèce aux contraintes thermique et hypoxique. Nous avons dans un premier temps caractérisé les modifications d'expression des gènes/protéines, par des approches transcriptomiques (RNAseq) et protéomiques (2-DE), dans un tissu, le manteau, d'animaux exposés à une contrainte thermique prolongée (56 jours). Nous avons ainsi pu identifier les voies majeures de régulation (eg., AP-1), les grandes fonctions (eg., cytosquelette) et processus (eg., apoptose) impliqués dans la réponse, mais également d'observer les grandes orientations du métabolisme (eg., dégradation des lipides de réserve). La réponse des organismes à l'hypoxie dépend de leur manière de gérer les faibles teneurs en oxygène. Nous avons d'abord, par une approche comparative avec une espèce intertidale, la moule (Mytilus spp.), caractérisée la réponse physiologique de la coquille Saint-Jacques à l'hypoxie. Nous avons pu ainsi déterminer ses paramètres d'oxyregulation, plus particulièrement son Point critique en 02 (Pc02). Le développement d'une approche protéomique, couplant l'effet de la température et de l'hypoxie, nous a ensuite permis d'identifier plusieurs protéines (CK2, GLN, etc.) potentiellement impliquées dans la réponse au niveau moléculaire. Enfin, dans l'optique de mieux comprendre la physiologie particulière de ces mollusques dans leur environnement naturel, nous avons comparé les signatures protéomiques de deux populations de P. maximus évoluant dans des écosystèmes contrastés, i.e. en limite nord- (Norvège) et au centre- (Brest) de l'aire de répartition de l'espèce. Les résultats suggèrent des différences majeures entre les deux populations au niveau du cytosquelette. En conclusion, ce travail ouvre des perspectives nouvelles pour la compréhension des mécanismes moléculaires régissant l'adaptation des mollusques aux contraintes thermiques et hypoxiques, deux stress particulièrement importants pour les organismes marins dans le contexte du changement global.

Coasts are among the most vulnerable ecosystems to the ongoing global changes, which result in increased water temperatures and frequencies of hypoxic episodes. The great scallop, Pecten maximus, is a subtidal species living at depths of 2-210 m. In spite of its commercial and major ecological values, only few studies at the molecular level were performed on this species. This thesis aimed at characterizing the molecular mechanisms implied in acclimation of this species to thermal and hypoxia stresses. We first characterized the…

L’huître creuse Crassostrea gigas est le produit aquacole le plus commercialisé dans le monde. Cependant, en France et dans d’autres régions du monde, des mortalités estivales massives affectent de façon alarmante les populations naturelles et cultivées de cette espèce, surtout aux stades juvéniles. Ces évènements sembleraient être liés à un déséquilibre entre les acteurs de la triade hôte – agent pathogène – environnement, favorisant l’affaiblissement des mécanismes de défense de l’hôte, et par conséquent, l’apparition et/ou l’augmentation de maladies. Parmi les facteurs environnementaux pouvant contribuer à ce déséquilibre, les contaminants chimiques sont connus pour moduler les capacités de défense de divers organismes aquatiques. Les phénoloxydases (PO) sont les enzymes-clés d’une cascade biochimique responsable de la production de mélanine et sont impliquées dans les défenses immunitaires et dans la reconnaissance du non-soi chez les invertébrés. Récemment, une activité de type PO a été détectée chez C. gigas, et a été proposée comme biomarqueur potentiel de la contamination chimique. Cependant, de nombreuses inconnues existent quant aux différents types d’activité PO présents chez C. gigas, et à leur implication dans les mécanismes de défense chez cette espèce. Dans ce contexte général,les objectifs de cette thèse ont été d’ 1) identifier les différents types de PO présents dans différents tissus de l’huître 2)évaluer le potentiel des PO en tant que biomarqueurs dans des expériences d’exposition in vivo à des contaminants organiques, 3) évaluer le potentiel des PO en tant que biomarqueurs dans des études de biosurveillance in situ. Nous avons pu montrer, pour la première fois chez cette espèce, l’existence de deux types d’activité PO : une activité catécholase et une activité laccase. De plus, nous avons pu mettre en évidence in vitro un effet bactéricide lié à l’activité des PO contre deux souches pathogènes de l’huître, Vibrio splendidus et V. aesturianus, dont leur présence a été fréquemment associée aux phénomènes de mortalités estivales. Enfin, grâce à une analyse multi-biomarqueurs sur différents tissus de C. gigas,l’ensemble des résultats ont permis de proposer que les PO pourraient être utilisées comme biomarqueurs de stress environnemental, plutôt que de contamination, dans la surveillance de la qualité des eaux côtières et estuariennes.

The Pacific oyster Crassostrea gigas is the leading aquaculture product at the worldwide level. However, massive summer mortalities affect dramatically cultivated and natural oyster populations, especially at young life stages. These events could be linked to an unbalance between the different actors of the triad host – pathogen agent – environment, which could favour a weakening of defence mechanisms in the host, and consequently, the emergence and/or increase of diseases. Among environmental factors that could contribute to this unbalance, chemical contaminants are known to modulate defence capacities in different aquatic organisms. Phenoloxidases (POs) are the…

Os moluscos bivalves sÃo alimentos de grande importÃncia nutricional sendo ususalmente consumidos nas regiÃes costeiras. Quando ingeridos in natura (crus) ou levemente cozidos, podem oferecer risco Ã saÃde pÃblica por serem filtradores e acumuladores de resÃduos quÃmicos e biolÃgicos, principalmente se a qualidade sanitÃria da Ãgua onde forem capturados estiverem comprometidas. A presente pesquisa tem como objetivo estudar a espÃcie Tagellus plebeius ("unha de velho") no estuÃrio do rio cearÃ em Fortaleza - Ce, considerando aspectos de seu ciclo reprodutivo, da sua biologia populacional e de suas condiÃÃes microbiolÃgicas. Para a anÃlise do ciclo reprodutivo os exemplares de T. plebeius foram coletados mensalmente no estuÃrio do rio cearÃ em Fortaleza - Ce (03, 42, 09.8 S; 35, 35, 49.0 W) no perÃodo de abril de 2006 a junho de 2007 em marÃs diurnas de sizÃgia. A cada mÃs as gÃnadas de 30 indivÃduos fram submetidas a exame histolÃgico. Para as amostragens microbiolÃgicas, as anÃlises foram feitas em dois meses da estaÃÃo seca )novembro e dezembro de 2006) e em dois meses da estaÃÃo chuvosa (marÃo e abril de 2007). Foram isoladas 22 cepas suspeitas de Salmonella spp., das quais 11 cepas foram confirmadas atravÃs do teste de sorologia com o antisoro polivalente O:H, sendo identificados 3 sorovares (S. Bredeney, S. London e S. Muenchen) e 1 (uma) cepa foi classificada atÃ subespÃcie: S. enterica subesp. enterica. Dentre os fatores ambientais observados neste estudo, a precipitaÃÃo pluviomÃtrica e a salinidade foram os que apresentaram as maiores amplitutes de variaÃÃo. O aumento da contaminaÃÃo por coliformes termotelorantes (45ÂC) na estaÃÃo chuvosa pode estar relacionado ao aporte de Ãgua doce no rio, como uma consequente diminuiÃÃo da salinidade associada a uma maior contaminaÃÃo bacteriologica. A correlaÃÃo significativa observada entre a salinidade e as fases "MaturaÃÃo/EliminaÃÃo Inicial" (M/E) e "Atresia Acular" (AC) mostra tambÃm a influÃncia desta variÃvel ambiental no desenvolvimento gonadal da espÃcie, prolongando ou reduzindo as fases do seu ciclo reprodutivo.

O alto da Bacia Hidrográfica do Rio Ribeira de Iguape foi submetido a intensa atividade mineira, cujo objeto mineral principal era a obtenção de chumbo (Pb). Durante longo período as condições de explotação foram rudimentares, não havendo controle sobre o impacto ambiental gerado durante as fases de extração e beneficiamento do minério, cujos rejeitos (escória e concentrado) foram lançados por anos diretamente no rio Ribeira de Iguape. Com o propósito de se criar uma indicação clara do comprometimento ambiental ou não da bacia hidrográfica do rio Ribeira de Iguape quanto ao teor dos metais Cd, Pb, Cr, Zn e Cu, este trabalho exibe resultados de valores que podem servir de referência em teor para estes metais. Para tanto, foram coletadas amostras de duas espécies de moluscos bivalves, Anodontites tenebricosus e Corbicula fluminea e de sedimento aluvionar, em uma porção localizada a montante das fontes de contaminação pelas atividades de mineração e fundição. Os moluscos foram coletados por exame tátil do substrato, seus tecidos foram separados das conchas, liofilizados e analisados em espectrômetro de massa (ICP/MS) e em espectrômetro de absorção atômica (AES). Os valores médios foram em sua maioria inferiores aos valores obtidos por outros autores em pontos localizados ao longo do rio Ribeira de Iguape sob a influência das atividades de mineração e fundição. Em relação às amostras de sedimento aluvionar estas foram separadas em duas porções, uma contendo sedimentos com minerais não magnéticos e a outra sedimentos com minerais magnéticos. Estas amostras foram tratadas granulometricamente e analisadas por fluorescência de raio X (FRX), a fim de se obter a concentração dos metais contidos em cada fração granulométrica. Nas amostras de sedimento não magnético, o composto químico em maior concentração foi SiO2. Quanto aos metais potencialmente tóxicos aqui investigados, todos foram encontrados nestas amostras. Já em relação ao sedimento magnético, as amostras exibiram constituição química composta principalmente por Fe2O3. Os metais Pb, Cr, Zn e Cu, foram encontrados em maior concentração nas amostras referentes as frações granulométricas mais finas, sendo a concentração do Cr nitidamente mais elevada. A elevada concentração deste metal nas amostras de sedimento magnético, quando comparada com as obtidas nas amostras não magnéticas, pode indicar uma provável origem do Cr a partir do mineral cromita (FeCr2O4). Estes dados juntamente com informações contida na literatura específica, indicam que provavelmente a origem do Cr, Pb, Zn e Cu na bacia do rio Ribeira de Iguape possui origem geogênica. De maneira geral, as concentrações dos metais potencialmente tóxicos aqui verificadas, tanto nas amostras referentes às duas espécies de moluscos quanto nas amostras de sedimentos, são inferiores, em sua maioria, às obtidas em pontos ao longo do rio Ribeira de Iguape estudados por outros autores onde há influência das atividades de mineração, o que permite considerar esses dados como referência.

La palourde grise européenne, Ruditapes decussatus est un coquillage d’importance socio-économique en Europe du Sud. Sa production est basée sur le recrutement naturel, qui est sujet à de fortes fluctuations annuelles. Au Portugal, les principales zones de production de cette espèce sont les lagunes de Ria de Aveiro et Ria Formosa. Ces populations présentent des réponses différentes à l'induction de la ponte, résultat d’intérêt dans un contexte d'amélioration de la production aquacole. L'objectif de cette thèse était d'améliorer les connaissances sur la reproduction de R. decussatus en utilisant des approches génomiques et cellulaires avec pour principales applications : le conditionnement de géniteurs et la qualité des gamètes.Le cycle de reproduction de ces populations a été caractérisé par histologie pour le développement gonadique, l’aire gonadique et le diamètre de l’ovocyte. À l'exception de la dynamique de la gamétogénèse, aucune différence significative n’a été identifiée entre populations. Grâce à un effort de séquençage (Illumina) de banque d’ADNc de différents tissus/stades pour enrichir en transcrits liés à la reproduction, une puce à ADN (oligoarray) représentant 51 678 contigs a été produite et utilisée afin de caractériser les bases transcriptomiques de la reproduction de R. decussatus. Des gènes différentiellement exprimés et la voie “N-Glycan biosynthesis”, impliquées dans l'interaction spermatozoïde – ovocyte, ont été soulignés, ce qui suggère que la reconnaissance entre gamètes puisse expliquer en partie les différences de succès d'induction de ponte entre ces populations. De plus, le transcriptome d’ovocytes collectés chez 15 femelles a été analysé par puce à ADN avec pour objectif d'identifier des potentiels marqueurs de la qualité des ovocytes. Des gènes codant pour des protéines chaperonnes, dont certains caractérisés comme des ARNm maternels essentiels pour le développement précoce, sont apparus différentiellement exprimés entre ovocytes de bonne et mauvaise qualité établie sur le taux de larves D obtenu. La présente étude fournit de nouvelles informations génomiques précieuses pour la compréhension de la reproduction de cette espèce et liste des gènes candidats codant la protéine disulforide isomerase (PDI), des calmodulines et la caspase 8 comme points de départ possibles pour des études fonctionnelles. Leur implication dans les phases importantes de la reproduction comme l’interaction spermatozoïde-ovocyte, la protection de l'ovocyte, la régulation du calcium et l'apoptose ont font des marqueurs potentiels de la qualité ovocytaire de cette espèce.

The European clam, Ruditapes decussatus is considered a high value seafood product in Southern Europe. Its production is almost based on natural recruitment, which is subject to annual fluctuations. In Portugal, two of the main production areas of this species are Ria de Aveiro and Ria Formosa Lagoons. These populations were characterized by different responses to spawning induction, which is of great interest in a context of improvement of…

L’huître du pacifique Crassostrea gigas est l'espèce marine la plus cultivée avec une production supérieure à 4 millions de tonnes pour l'année 2010. En France, C. gigas est cultivée depuis la fin des années 1970. Cependant, cette espèce souffre d’un syndrome de mortalité estivale depuis les années 1980, avec une amplification depuis 2008 qui touche jusqu'à 100 % des naissains. Ce syndrome de mortalité est un phénomène multifactoriel, basé sur l’interaction de nombreux facteurs: stress environnementaux, caractéristiques physiologiques et génétiques de l’huître, présence et virulence de pathogènes. L’huître du pacifique C. gigas est une espèce estuarienne qui est soumise aux pressions anthropiques comme la pollution du milieu côtier. Ces événements représentent des sources potentielles de stress en zones ostréicoles. Cependant, les connaissances sur les effets des polluants comme les pesticides sur C. gigas restent fragmentaires. Les périodes d’épandage d’herbicides coïncident parfois avec la période de reproduction des huîtres, raison pour laquelle nous considérons que ces produits chimiques pourraient affecter la génération suivante d'huîtres. Parmi les pesticides, le diuron est le plus fréquemment détecté sur les côtes françaises, avec une concentration maximale rapportée de 0,78 µgL-1. L'exposition directe aux herbicides affecte le transcriptome des huîtres qui est le premier niveau de réponse face à l'exposition du polluant. Il a été démontré que l'exposition parentale au diuron a des effets génotoxiques chez C. gigas au stade de naissain. Une variabilité phénotypique de trait d’ histoire de vie a été observée aussi pour ces naissains. Un autre effet possible des pesticides serait la modification de marques épigénétiques. Il est connu que les facteurs environnementaux telle que la pollution par des composés chimiques peuvent modifier l'épigénome et par conséquent le phénotype des individus et de leurs descendance en agissant au niveau trans-générationnel. Ces dernières observations nous permettent d’émettre l’hypothèse de l’implication de mécanismes épigénétiques suite à l’interaction avec des produits phytosanitaires. Ces mécanismes modifieraient le phénotype des huîtres au stade de naissains par l'exposition parental. Pour tester cette hypothèse nous avons étudié la méthylation globale de l'ADN (méthylome), qui est un de principal marques épigénétiques, et le transcriptome des naissains issus de géniteurs exposé au Diuron. Nous avons identifié des modifications du méthylome et du transcriptome qui ont un lien avec le phénotype de trait d'histoire de vie de ces naissains. Ces résultats démontreraient qu’une exposition indirecte ou parentale du diuron modifie la méthylation et l'expression de fonctions de gènes spécifiques, expliquant en partie la variabilité phénotypique observée.

A Anomalocardia brasiliana está entre os moluscos bivalves marinhos mais coletados em Pernambuco, região nordeste do Brasil, esse marisco é naturalmente encontrado principalmente no litoral norte, onde a pesca artesanal sempre foi uma atividade tradicional. O presente estudo teve como objetivo avaliar as relações alométricas no crescimento e peso do marisco A. brasiliana, na praia de Mangue Seco, litoral norte de Pernambuco. Para verificar se o marisco apresentou alometria positiva, negativa ou isometria, foram realizadas regressões não lineares (metodologia Gauss Newton) entre as medidas comprimento/largura, comprimento/altura, largura/altura, peso da concha/peso partes moles e comprimento/peso (total, concha e parte mole). Ao realizar as análises da A. brasiliana verificou-se que a relação comprimento/largura foi alométrico positivo e as demais relações foram negativas. Os resultados desse estudo podem ser utilizados na elaboração de planos de manejo para o desenvolvimento da pesca e maricultura e servir como base para diagnosticar efeitos ocasionados por possíveis alterações ambientais.

Anomalocardia brasiliana is one of the most common bivalve marine mollusks found in Pernambuco, in the Northeast of Brazil. This shellfish is mainly found on the northern coast of the region, where hand fishing has always been a traditional activity. The aim of the present study was to assess the allometric ratios of growth and weight of the shellfish A. brasiliana, on Mangue Seco beach, in northern Pernambuco. Non-linear regression was performed (Gauss Newton methodology) to investigate if the shellfish exhibited positive, negative or isometric allometry using the following measurements: length/width; length/height; width/height; weight of the shell/soft tissue weight and length/weight (total, shell and soft tissue). Analysis of A. brasiliana confirmed that the length/width ratio was positively allometric whereas all other ratios were negative. The results of the present study may be used in the preparation of management plans for fishing and mariculture development and as a basis to diagnose possible effects caused by environmental changes.

▼ Les mitochondries, organites essentiels à la production d'énergie, possèdent leur propre matériel génétique : l'ADN mitochondrial (ADNmt). Chaque produit des gènes de I'ADNmt interagit avec des protéines codées par l'ADN nucléaire pour assurer la respiration mitochondriale. Dans le règne animal, I'ADNmt est transmis exclusivement de façon maternelle. La transmission maternelle permettrait d'éviter les conflits intergénomiques. Il existe un seul système mitochondrial qui transgresse singulièrement les lois de la transmission et de la génétique de I'ADNmt, il s'agit de la double transmission uniparentale [doubly uniparental inheritance (DUI)]. L'existence de la DUI a été démontrée chez sept familles de mollusques bivalves, dont les moules marines : Mytilidae; les palourdes marines : Veneridae, Solenidae et Donacidae et les moules d'eau douce : Unionidae, Margaritiferidae et Hyriidae. Les espèces possédant ce système atypique sont caractérisées par la présence de deux ADNmt distincts qui sont hérités de façon maternelle (ADNmt F) et paternelle (ADNmt M). Typiquement, les femelles sont homoplasmiques et contiennent uniquement I'ADNmt F tandis que les mâles sont hétéroplasmiques. Chez ces derniers, I'ADNmt F domine dans les tissus somatiques alors que la gonade contient presque exclusivement I'ADNmt M. Les divergences observées entre les ADNmt F et M chez les moules peuvent atteindre ~50% en acides aminés. Ce haut niveau de divergence observée entre les génomes M et F, coexistant à l'intérieur d'un même individu soulève de nombreuses questions d'ordre évolutives. La double transmission uniparentale représente, certes, un système atypique, mais les descriptions, les comparaisons et les analyses qu'elle permet contribuent à développer une image plus exacte de l'évolution non seulement au niveau de l'évolution de la DUI, mais aussi au niveau de l'évolution du génome mitochondrial dans son ensemble. L'objectif de la présente thèse est d'utiliser une approche comparative de données moléculaires pour mettre en évidence l'évolution des génomes mitochondriaux mâle et femelle du système de la double transmission uniparentale chez les moules unionoïdes. Chez ce groupe, la double transmission uniparentale semble évolutivement plus stable (aucun évènement de recombinaison ou de masculinisation n'a été recensé) et la divergence entre les ADNmt M et F est significativement plus élevée que chez les taxons marins. Le chapitre II est une revue de littérature sur le système de la double transmission uniparentale. Les observations qui ont menées à la découverte de la DUI y sont présentées de même que le modèle et les mécanismes de la DUI. Cette revue propose la DUI comme un système modèle qui pourrait permettre d'acquérir de nouvelles connaissances sur les interactions et la coadaptation des génomes nucléaires et mitochondriaux. L'objectif du chapitre III était de séquencer, d'annoter et de publier pour la toute première fois des génomes mâles complets d'Unionoïdés. Six nouveaux génomes mitochondriaux complets d'espèces d'Unionoïdés, soit…

Estudos ecotoxicológicos podem ser empregados na avaliação da qualidade de ecossistemas, por meio do uso de biomarcadores, que são alterações em parâmetros em nível subindividual que indicam que um organismo foi exposto a contaminantes. Os bivalves são organismos frequentemente utilizados em estudos ecotoxicológicos e a espécie Corbicula fluminea (Corbiculidae) está entre aquelas que mais aparecem nos estudos realizados em ambientes dulcícolas. O chorume produzido em lixões e aterros de resíduos domésticos é uma mistura complexa e variável que contém diversos tipos de compostos tóxicos, tais como metais e compostos orgânicos xenobióticos, os quais podem causar alterações em biomarcadores de animais aquáticos. No presente trabalho, fez-se o uso de biomarcadores para avaliar a toxicidade do chorume em bivalves C. fluminea em dois tipos distintos de testes de toxicidade. Foram realizados testes de toxicidade in situ em três pontos (P1, P2 e Periq3) de um córrego contaminado por chorume de aterro doméstico e, também, testes de toxicidade em laboratório com diferentes diluições (10X, 18X, 32X e 50X) do chorume bruto retirado do mesmo aterro controlado. Os biomarcadores avaliados foram de biotransformação de xenobióticos (EROD: 7-etoxiresorufina-O-deetilase; GST: glutationa S transferase; MXR: mecanismo de resistência a multixenobióticos), estresse oxidativo (ERO: geração de espécies reativas de oxigênio; CAO: capacidade antioxidante total; LPO: lipoperoxidação), danos no DNA (ensaio do cometa), conteúdo de metalotioneínas (MT) e expressão relativa dos genes piGST e MT. Além disso, nos testes de toxicidade in situ foi avaliado o acúmulo dos metais Al, Cd, Cr, Cu, Mn, Ni e Pb nas brânquias e glândulas digestivas dos bivalves. Nos testes realizados em laboratório também foram analisadas a expressão gênica dos genes da GST e MT, nos bivalves expostos por 5 dias a diluição de 50X. Os resultados mais relevantes mostram que o chorume, independente do tipo de teste de toxicidade empregado, provoca a redução da atividade da EROD em brânquias e indução na glândula digestiva, o aumento da atividade da GST, a redução do MXR, ocorrência de LPO e aumento do conteúdo de MT. O ensaio do cometa realizado mostrou que danos no DNA de hemócitos de bivalves C. fluminea ocorrem a partir de 15 dias de exposição ao chorume. O metal Cr teve maior acúmulo nos tecidos dos bivalves confinados nos três pontos do córrego contaminado por chorume, podendo este ser um potencial contaminante do chorume com ação tóxica sobre os bivalves. Conclui-se que mesmo nos experimentos em campo ou em laboratório o chorume foi tóxico para os bivalves, que apresentaram alterações mesmo no ponto mais distante da fonte de chorume e na maior diluição testada. Isto mostra que o tratamento ou diluições do chorume precisam ser maiores ou mais eficientes para evitar danos mais severos e permanentes a biota aquática.

▼ Spencer Gulf is a large, shallow, metahaline embayment along the southern Australian continental margin (~22,000 km2, > 60 m water depth). The gulf experiences inverse estuarine circulation and seasonally fluctuating water temperatures, salinities, and nutrient levels. The gulf floor is covered with temperate carbonate sediments (sands, gravels, and muds) that are skeletal remains of heterozoans; bivalves, coralline algae (rhodoliths), bryozoans, benthic foraminifera, and echinoids are common constituents throughout. These carbonates are interpreted to be accumulating in five depositional environments: dense seagrass meadows, sand flats with sparse seagrass growth, rhodolith pavements, open gravel/sand barrens, and muddy seafloors. Detailed seasonal oceanographic data and hydrodynamic model outputs were used to delimit oceanographic influences on sedimentation patterns. The depth of the euphotic zone is interpreted as the most important control on benthic environment distributions within the gulf. Salinities, hydrodynamics, and nutrient concentrations also affect biological assemblages and facies patterns. Seagrasses and rhodoliths require sufficient light for growth and, thus, compete for space on euphotic seafloors. Seagrasses colonize the shallowest, best-illuminated areas. Rhodolith pavements occur in regions of the gulf where seagrasses are excluded: seafloors where surface-water nutrients promote growth of phytoplankton that decrease light penetration, and energetic channels with high bottom-water currents. Calm, subphotic seafloors are characterized by soft sediment environments (open gravels, sands, and muds). Benthic calcareous organisms are surprisingly diverse throughout the gulf, despite elevated seawater salinities (up to 47‰). Abundant carbonate muds set Spencer Gulf apart from other shallow temperate provinces. The origin of this mud is primarily from the breakdown of skeletal particles via maceration. Mineralogical composition is, therefore, a mixture of aragonite, intermediate-Mg calcite, and low-Mg calcite. Rhodolith pavement deposits were investigated in detail to determine how oceanographic conditions influence sedimentation in these environments. Rhodolith pavements provide habitats for diverse calcareous invertebrates, which can be used as environmental indicators. The rhodoliths themselves within Spencer Gulf, however, do not show morphological differences that can be used as indicators of water energy levels, as some authors have suggested. This study demonstrates that integration of detailed oceanographic data and facies analysis aids interpretations of benthic environments and sediment distribution patterns.

▼ This thesis investigates the reason(s) for an anomalous distribution of mussels on Wellington’s South Coast. Wellington Harbour supports large populations the mussels (Perna canaliculus, Aulacomya maoriana and Mytilus galloprovincialis) however; all these species are absent from the nearby South Coast. The physical difference between Harbour and Coastal sites was confirmed from water samples taken at eight sites inside and outside Wellington Harbour between September 1998 and February 2000. These data showed significant differences between Harbour and Coastal sites in seven of eleven parameters tested. Larval densities were investigated at Harbour and Coastal sites; data showed larval density to be approximately an order of magnitude greater in Harbour waters compared to the Coast. Larval density in Coastal waters reached a maximum of 380 mˉ³ and is therefore not expected to be a major limiting factor. Similar results were found for studies of settlement density on artificial substrates. Settlement at Harbour sites was approximately 10 times that at Coastal sites, however, mussel densities of up to ≈3700 mˉ² at Coastal sites indicate that settlement is also unlikely to be a factor contributing to mussel absence. Comparisons were made of body condition index between Harbour mussels and those from the Harbour relocated to the Island Bay Marine Laboratory (IBML) on Wellington’s South Coast. All mussel species experienced a significant decrease in condition at IBML when compared with those from the parent population in Wellington Harbour. Levels of mortality were high in P. canaliculus (60%) and M. galloprovincialis (70%) and moderate in A. maoriana (30%). This indicated the possibility of nutrient limitation as a cause of mussel absence. This was corroborated by a similar study using RNA:DNA ratio as a biochemical index of condition. Mussels held at IBML experienced a significant decrease in RNA:DNA compared to those from the parent population within the Harbour. Further investigation of nutrient limitation was conducted by way of feeding experiments to estimate the scope for growth (SFG) of each mussel species. In P. canaliculus, SFG had a mean (±SD) of 45.6 J gˉ¹ hˉ¹ (±78.9) and only 27% of observations were negative. A. maoriana had lower SFG estimates, mean SFG was 19.1 J gˉ¹ hˉ¹ (±66.7) and negative SFG was recorded 43% of the time. M.galloprovincialis had mean SFG of 1.26 J gˉ¹ hˉ¹ (±39.1), 52% of SFG estimates were negative. While these data do not overwhelming support the hypothesis of nutrient limitation, they do go some way toward corroborating the findings of the condition index experiments. Models to predict SFG were derived from data in the feeding experiments, these models were derived from a small range of low seston concentrations. A second group of models was derived from studies conducted by Gardner (2001) to give a broader range of seston concentrations. Seston data from the water sampling described above were used to estimate SFG at eight sites inside and outside the Harbour over the period from… Advisors/Committee Members: Gardner, Jonathan.

▼ Catastrophic sedimentation events create one off disturbances that can cause mass mortality events in receiving estuaries. In contrast, the deposition of small amounts of terrigenous sediment (TS) is on-going and likely to have long-term consequences for benthic communities who, play important roles in ecosystem functioning. The aim of this thesis was to look at the effects of small amounts of TS on the behaviour of an infaunal deposit-feeding bivalve (Macomona liliana), which may have implications for sediment porewater fluxes and ecosystem functioning. To determine the effect of TS on behaviour, mesocosm experiments in a recirculating flume tank were run. Time lapse imagery was used to capture surface activity, and high resolution pressure sensors were buried within the sediment and captured changes in hydraulic activity. The effect of three TS treatments were tested, low, high and mixed. The low and high treatments were surface additions of TS (0.09 g cm -2 and 0.20 g cm -2, respectively) and represented the initial deposition and build-up of TS. The mixed treatment, mixed 0.20 g cm -2 through the top 2 cm of sediment, to mimic the incorporation of TS into marine sediments over time. Behaviours were observed pre- and post-treatment addition, and were compared to determine the effect of TS on M. liliana behaviour. The surface (top 2 cm) sediment properties were measured to determine the degree of surface modification by the TS treatments. TS significantly modified the properties of the sediment surface and the hydraulic conductivity. These caused subtle, but significant, changes in some of the behaviours observed in M. liliana, and on a whole, behaviour which bioturbated the sediment surface decreased. Two feeding modes were observed at the surface, deposit-feeding and suspension-feeding/ventilation. There was a switch in feeding modes, from deposit-feeding to suspension-feeding/ventilation, in the low and mixed treatments. The duration of suspension-feeding/ventilation was, on average, three times longer than deposit-feeding, across all treatments, therefore a switch in modes altered the temporal patterns of sediment pressurisation. The amplitude of sediment pressurisation during feeding was significantly increased in the mixed treatment (up to 5× higher) as a result of decreased hydraulic conductivity. Additionally, the pressure signal measured during deposit-feeding was twice that of suspension-feeding/ventilation in the mixed treatment. Collectively the short-term changes in M. liliana behaviour are likely to increase sediment stability and the persistence of TS in the environment, potentially causing long-term degradation to habitat and M. liliana condition. As a result of reduced hydraulic conductivity, larger porewater fluxes are likely to be generated in the mixed treatment, and this would be two fold larger during deposit-feeding than in suspension-feeding/ventilation. This paired with the different temporal scales of the two feeding modes, and the observed switches in feeding modes, would have… Advisors/Committee Members: Pilditch, Conrad A (advisor), Townsend, Michael (advisor), Thrush, Simon F (advisor).

Mestrado em Engenharia Alimentar - Qualidade e Segurança Alimentar / Instituto Superior de Agronomia

A espécie Callista chione (ameijola), é um bivalve consumido em cru ou levemente cozinhado, podendo esta forma de consumo representar risco para a saúde dos consumidores. O objetivo deste trabalho foi determinar a composição nutricional da ameijola (proteína, humidade, cinza, gordura, glicogénio, perfil de ácidos gordos e elementos essenciais), o teor de contaminantes químicos (mercúrio, chumbo e cádmio) e microbiológicos em três períodos do ano (Inverno, Primavera e Verão), estudando-se também o efeito do tratamento térmico e da evisceração. As ameijolas (entre 5,5 e 8,7 cm de comprimento) foram capturadas na zona litoral Setúbal-Sines. Este bivalve apresenta níveis de humidade de cerca de 80 g/100 g e um teor de proteína de 15 g/100 g. Embora o teor de gordura seja baixo (entre 0,3 e 0,7 g/100 g), o perfil de ácidos gordos é interessante, apresentando maior teor de ácidos gordos polinsaturados, nomeadamente ómega 3, seguindo-se os saturados e os monoinsaturados. O seu conteúdo dos elementos essenciais, apresenta o perfil: Na>K>P>Mg>Fe>Mn>Zn>Ni>Cu>Cr. Os níveis dos contaminantes químicos estão bastante abaixo dos teores máximos admissíveis. A E. coli, os coliformes e os microrganismos viáveis totais apresentam sempre valores inferiores aos limites permitidos. De uma forma geral, a evisceração não representa efeitos significativos nos parâmetros estudados, chegando a ter um efeito negativo. Em relação à sazonalidade, a Primavera parece ser a época onde há maior disponibilidade de alimento. As maiores diferenças entre as amostras cozidas e cruas verificam-se nos teores de humidade, cinza, gordura livre, ácido eicosapentaenóico, ferro e potássio, devido a uma perda de água durante o processamento térmico. Em suma, esta espécie provém de uma zona considerada limpa podendo ser apanhada e comercializada para consumo humano direto. No entanto, é aconselhável que se realize uma congelação e um ligeiro processamento térmico para garantir níveis de microrganismos aceitáveis e acompanhar sempre que necessário as interdições, de forma a garantir a segurança do consumidor

▼ Native (Chione californiensis) and non-indigenous bivalve species [Musculista senhousia (now known as Arcuatula senhousia), and Venerupis philippinarum] were collected from Mission Bay, San Diego, California and exposed to copper contaminated water at estimated concentrations of 0 ppb, 25 ppb, and 50 ppb over the course of two experimental periods of 18 days and 12 days. Bivalves were placed in tanks in a temperature controlled environment, and measurements of a number of parameters were taken during and after the exposure to copper: survivorship, feeding rates, growth, mucus production, and tissue copper concentrations for the entire body, gills, and digestive tract. These factors were analyzed on their own and in comparison to tissue copper concentration to examine potential relationships. Observations indicated that there were several statistically significant differences, either between copper concentration groups, between species, or both. The majority of sublethal measures showed no statistically significant differences across both experiments, with the exception of whole body copper accumulation. Whole body copper accumulation showed significant differences between Musculista and both Chione and Venerupis, and may suggest a competitive disadvantage in copper contaminated environments, as Chione and Venerupis may be more efficient at removing copper from tissue. Other sublethal measures that did show significance did not show consistency across both experiments or showed contradicting trends, and none showed consistently significant trends when compared with tissue copper concentrations. Algae depletion rate measurements produced inconclusive results. The data indicates that most sublethal biomarkers used in this experiment were not indicators for copper toxicity for the species in this experiment at the tested concentrations, and that of those species, Chione was the most resistant to the effects of copper with respect to mortality and whole body accumulation.
