▼ Target species in some Australian shark fisheries are adequately managed, but there has been little attention given to non - target shark species and there is limited information on the biology of their local populations. Among this group of non-target species, the piked spurdog - Squalus megalops ) is of special interest because it is a dominant and ecologically important species with high natural abundance. Hence, the main purpose of the present research was to improve knowledge of the basic biology of this species and to provide essential data for its management, sustainable use and conservation. Squalus megalops had a complex population structure, segregating by sex, size and breeding condition. The sex ratio was biased towards females and there was sexual size dimorphism with females attaining a larger maximum size than males. Conversion factors from partial lengths to total length and from partial masses to total mass were determined due to the common commercial fishing practice of eviscerating, beheading and finning sharks. Comparisons of total and partial length - length and mass - length relationships between males and females using different ranges of size showed that there was no effect of size range on measurements reflecting only somatic growth ( fork and carcass lengths ; carcass, pectoral fin and caudal fin masses ). However, for variables reflecting somatic and reproductive growth ( total and liver masses ), different outcomes can be expected when different ranges of size are compared. Examination of dietary composition revealed that S. megalops is an opportunistic predator that consumes a wide range of prey items. High variability was found when overall importance of prey items was estimated. Dietary composition varied in space and time, exhibiting differences among regions, seasons and size classes. Therefore, the intrinsic natural variability in the dietary composition of S. megalops and its spatial and temporal variation in diet suggest that information on the ecological relationships among species is likely to be missed when predator - prey interactions are only inferred from overall diet. Reproductive parameters were determined for population assessment. For both sexes, length - at - maturity differed depending on the criterion adopted for defining maturity. Mature males are capable of mating throughout the year. Females have a continuous asynchronous reproductive cycle. The sex ratio of embryos is 1 : 1 and litter size and nearterm embryo size increase with maternal length. Females have an ovarian cycle and gestation period of two years. Although all females are mature at 600 mm, only 50 % of them are in maternal condition, contributing to annual recruitment each year. Hence, for chondrichthyan species with reproductive cycles of two, three or more years, if maturity ogives are used in population assessments instead of maternity ogives, the models will over - estimate recruitment rates. Age and growth information was also determined for population assessment. Precision estimates, the… Advisors/Committee Members: Walker, Terry (advisor), School of Earth and Environmental Sciences (school).

▼ Depredation within fisheries occurs when a predator preys upon target species caught within fishing gear. In many cases predators can be habituated to commercial catches from fisheries, especially when prey are too large or too fast for the predator to forage successfully in the natural system. Depredation in fisheries has received much attention over the last few decades in light of conservation and economic implications. Current knowledge is still focused, however, on the direct impacts of depredation on fisheries (e.g. financial losses), or predator populations, without consideration of the implications for prey populations. Recent advances in predator–prey theory have demonstrated that predation not only generates direct impacts on prey populations via consumption, but also has indirect impacts via causing changes in prey activity, behaviour, physiology and development, i.e. ‘non-consumptive’ effects of predation or predation risk. For example, prey under predation risk are forced to make behavioural choices between vital activities, such as feeding and predator avoidance, by reducing activity or seeking out shelters. Hence, individual-level decision making (e.g. sheltering vs feeding) can have profound implications on prey life history traits such as survival, growth and reproduction, which can in turn impact populations and ecosystems. In regards to the prey, consumptive and non-consumptive effects have not yet been thoroughly examined in a fishing context, particularly on fishing grounds where predator habituation to fishing gear occurs and the implications may be extended to the prey population. In this thesis, the interaction between the Maori octopus (Pinnoctopus cordiformis) and the southern rock lobster (Jasus Edwardsii) is used as a predator–prey case study, with particular emphasis on octopus depredation within the southern rock lobster fishery (SRLF) in Australia. A multi-level approach examines predation risk at the population level from fishery-dependent information on fishing grounds, and at the individual level from laboratory experiments designed to elucidate the physiological responses of lobsters under predation risk. In-pot lobster mortality is used as a proxy of predation risk for the fishery (i.e., ‘in-pot predation risk’), and its examination across spatial and temporal scales and with a range of life history traits forms the basic understanding of this case study. At a finer-scale individual level, information from experiments provides new insights on prey decision-making processes under predation risk, elucidating the non-consumptive effects of octopus predation on lobster. Specifically, this study comprises four linked, but stand-alone, chapters addressing the following: understanding spatio-temporal patterns of octopus predation in the SRLF (Chapter 2) and the identification of lobster life history traits associated with octopus depredation in the SRLF (Chapter 3); and the examination of physiological responses of adult J. Edwardsii under predation risk (Chapter 4); and how such…

▼ The American lobster (Homarus americanus) support one of the most valuable fisheries in the United States. A growing body of literature recognizes the importance of environmental variables in regulating this species’ biogeography and population dynamics. However, the current lobster stock assessment and management do not explicitly consider the impact of environmental variables such as water temperature and assumes spatiotemporal variabilities in the lobster environment as random background noises. Furthermore, while climate-induced changes in marine ecosystems continue to impact the productivity of lobster fisheries, studies that model lobster response to altered environmental conditions associated with climate change are lacking. As such, evaluating changes in lobster biogeography and population dynamics, as well as explicitly incorporating quantified lobster response to altered environmental conditions into the specie’s stock assessment will be critical for effective lobster fisheries management in a changing environment. This dissertation research developed a modeling framework to assess and incorporate environmental variability in assessment and management of American lobster stocks in the Gulf of Maine, Georges Bank, and southern New England. This modeling framework consists of: 1) a qualitative bioclimate envelope model to quantify the spatiotemporal variability in availability of suitable lobster habitat; 2) a statistical climate-niche model to quantify spatiotemporal variability of lobster distribution; and 3) a process-based population size-structured assessment model to incorporate the effect of environmental variable such as water temperature in lobster population dynamics. The developed modeling framework was used to predict climate-driven changes in lobster habitat suitability and distribution, as well as to determine whether incorporating the environmental effects can better inform historical recruitment especially for years when recruitment was very low or very high. The first component of the framework provides a qualitative bioclimate envelope model to evaluate the spatiotemporal variability of suitable lobster habitat based on four environmental variables (bottom temperature, bottom salinity, depth, and bottom substrate type. The bioclimate envelope model was applied to lobsters in Long Island Sound and inshore Gulf of Maine waters. In the Long Island Sound, an examination of the temporal change in annual median habitat suitability values identified possible time blocks when habitat conditions were extremely poor and revealed a statistically significant decreasing trend in availability of suitable habitat for juveniles during spring from 1978 to 2012. In the Gulf of Maine, a statistically significant increasing trend in habitat suitability was observed for both sexes and stages (juvenile and adult) during the spring (April–June), but not during the fall (September–November). The second component of the framework provides a statistical niche model to quantify the… Advisors/Committee Members: Yong Chen, Richard Wahle, Damian Brady.

1. Introduction – 2. Status of the Sydney rock oyster in a disease-afflicted estuary: persistence of wild populations despite severe impacts on culture counterparts – 3. Are native Saccostrea glomerata and invasive Crassostrea gigas oysters habitat equivalents for epibenthic communities in south-eastern Australia? – 4. Substrate or sink? Differences in settlement of Saccostrea glomerata larvae on non-native Crassostrea gigas and conspecifics is determined by spatial arrangement – 5. Differences in the shell strength of native and non-native oysters do not influence their susceptibility to a generalist predator – 6. General conclusions.

As a consequence of rising global consumption of seafood and over-extraction of wild finand shell-fisheries, aquaculture is the fastest growing food production method in the world. Although in some instances aquaculture may benefit wild populations by deflecting harvest pressure away from these, in others it may have negative impacts as a consequence of facilitation of disease or biological invasion or where it results in genetic pollution of wild populations with selectively-bred genotypes. The oyster industry of New South Wales (NSW), Australia, is presently entirely dependent on aquaculture. Although the NSW industry historically cultured wild-caught native Sydney rock oysters (Saccostrea glomerata), in recent years high mortality of cultured oysters from QX disease has led to a shift towards culture of Sydney rock oysters selectively bred for disease resistance and non-native Pacific oysters (Crassostrea gigas) that are unaffected by the disease. It is unknown how QX disease or the resulting strategies of management that have been applied to the aquaculture industry (culture of disease resistant Sydney rock or Pacific oysters) may impact wild populations of Sydney rock oysters, and their important ecosystem services, which include provision of habitat and food for associated communities of fish and invertebrates. This thesis determined: (1) how QX disease has impacted wild populations of Sydney rock oysters, both directly and indirectly as a result of any facilitation of Pacific oysters, and (2) whether wild-stock Sydney rock oysters, disease resistant Sydney rock oysters, and Pacific oysters are functionally equivalent in their provision of habitat and food to associated communities of invertebrates. – Sampling in the Hawkesbury River, NSW, where QX disease has produced aquaculture mortality of Sydney rock oysters of up to 90%, revealed only a low (<14%) prevalence of the disease-causing parasite among wild Sydney rock oysters on rocky shores. Consequently, mortality rates of wild Sydney rock oysters remained low and there was no evidence of replacement of populations of Sydney rock oysters with disease-resistant Pacific oysters. Field and laboratory experiments showed that even under the scenario that aquaculture facilitates invasion of Pacific oysters or causes genetic modification of wild Sydney rock oyster populations, little change…

▼ By permitting the integration of multiple forms of knowledge through joint fact-finding, it is suggested that collaborative governance approaches can produce more holistic and place-based understandings of environmental problems and help to alleviate conflict among stakeholders over the knowledge that is used to make decisions. Despite the central role of knowledge in collaborative processes, research in the collaborative environmental governance field to-date has provided limited practical insight into what they can and cannot achieve or how processes should be structured and run to produce successful outcomes related to knowledge production and use. This study seeks to address this gap in the literature through three specific research objectives: (1) to develop a theoretical framework for analyzing knowledge production and use in collaborative environmental governance; (2) to use the framework to analyze knowledge production and use in a real-world collaborative environmental governance process; and (3) to offer recommendations for designing or adapting collaborative environmental governance processes to better achieve the goals of collaboration related to knowledge production and use. A multiple case study approach was used to analyze knowledge production and use in a collaborative water allocation planning process in South Australia. The findings affirm that a number of theorized process and outcome criteria associated with successful knowledge production and use are achievable in practice. Despite limited evidence that local actors were involved directly in producing knowledge within the processes that were examined, the findings showed that participants in at least one of the cases were able to achieve a high level of understanding and acceptance of the knowledge used to base policy decisions, as well as to build social capital among scientists and local participants. This paradox draws attention to limits of current theories in the collaborative environmental governance literature for designing and implementing successful collaboration and offers important insights for evaluating collaborative processes. The study also provides a preliminary set of recommendations for structuring and executing collaborative processes to achieve successful outcomes related to knowledge production and use. While the findings of this study relate most directly to the water allocation planning system in South Australia, they are also transferable to other collaborative institutions, particularly those that are nested within a more traditional top-down system of governance.

▼ Assessment of trophic interactions between increasing populations of New Zealand fur seals (Arctocephalus forsteri) and fisheries in southern Australia is limited due to a lack of species specific demographic data and an understanding of the factors influencing population growth. To establish species specific demographic parameters a cross-sectional sample of New Zealand fur seal females (330) and males (100) were caught and individually-marked on Kangaroo Island, South Australia between 2000 and 2003. The seals were aged through examination of a postcanine tooth, which was removed from each animal to investigate age-specific life-history parameters. Annual formation of cementum layers was confirmed and accuracy in age estimation was determined by examination of teeth removed from individuals of known-age. Indirect methods of assessing reproductive maturity based on mammary teat characteristics indicated that females first gave birth between 4-8 years of age, with an average age at reproductive maturity of 5 years. Among reproductively mature females, age-specific reproductive rates increased rapidly between 4-7 years of age, reaching maximum rates of 70-81% between 8-13 years, and gradually decreased in older females. No females older than 22 years were recorded to pup. Age of first territory tenure in males ranged from 8-10 years. The oldest female and male were 25 and 19 years old, respectively. Post-weaning growth in females was monophasic, characterised by high growth rates in length and mass during the juvenile growth stage, followed by a gradual decline in growth rates after reproductive maturity. In contrast, growth in males was biphasic and displayed a secondary growth spurt in both length and mass, which coincided with sexual and social maturation, followed by a rapid decline in growth rates. Age-specific survival rates were high (0.823-0.953) among prime-age females (8-13 yrs of age) and declined in older females. Relative change in annual pup production was strongly correlated with reproductive rates of prime-age females and adult female survival between breeding seasons.

▼ After more than a decade of environmental impact assessment ( EIA ) provisions within South Australian Planning Act, 1982 it is appropriate to examine the role of the environmental impact statement ( EIS ) as a major element of EIA and an important decision making tool for major projects over this period. The thesis first provides a review of EIA from its overseas origins to its development at the Commonwealth level in Australia. This provides the context within which to examine the system of EIA for major developments or projects in South Australia, which are dealt with largely through the EIS process. The thesis examines the type of projects which, according to the discretionary criteria in the Planning Act, have attracted EIS requirements between 1982 - 1993 and uses this to determine generic groupings of projects. It is noted that marinas represent the largest group of projects with EIS requirements, although EISs have been called for power generation related projects, electricity transmission line projects, tourist related projects, industrial projects, mining projects, water management projects, transport projects and a number of other projects. The thesis examines the number of EISs that have been completed, whether or not the projects have been approved or rejected and to what extent any patterns have emerged. The thesis then focuses on all the completed EISs in terms of their content, timing of preparation, public involvement and response, associated legislative requirements, type and role of developer, type and role of EIS consultant, the assessment of the EIS, and the decision making process. The thesis notes the high approval rate for projects with completed EISs suggesting most of the environmental problems have been resolved or are capable of being resolved. It is also noted that a number of projects are abandoned before the EIS is ever completed and that the few rejected EIS proposals are associated with high numbers of public submissions. Although each of the rejected proposals has a complex history of project development, environmental assessment and negotiations, it is noted that the decision to reject the proposals was ultimately a political decision. The thesis comments on the limited role of the South Australian Planning Commission ( SAPC ) in EIS project decision making in South Australia and the increasing use of the Governor as a decision maker. Although the SAPC is the statutory planning authority it is constrained by having to have regard to the principles in the Development Plan which is geared toward development control rather than for the extraordinary major projects which become subject to EIS requirements. The thesis then examines proposed changes to EIA in the context of early attempts to initiate EIA reform in South Australia through to the current Development Bill. These proposals are placed in context with changes to EIA procedures that have taken place at the Commonwealth level, the proposed development of a national agreement on EIA, and also the implications for EIA which are… Advisors/Committee Members: Radford, Tony (advisor), Bunker, Ray (advisor), Department of Architecture (school).

▼ During the period April 1994 and February 1996 as part of an investigation into the national Iinefishery, the east coast shore fishery and the recreational and commercial ski-boat fisheries were surveyed, at eight sites between Kei Mouth in the East and Stil Bay in the West. Roving creel, access point and aerial surveys were used. A questionnaire was developed for each sector to gather data on catch and effort, fisher demographics, economics, fisher attitudes towards, and knowledge of, the current management regulations and assess the efficacy of the fisheries inspectorate. During the access point survey the catch of 3273 fishers was inspected and 1556 interviews were conducted. Questionnaires were conducted on 118 recreational ski-boaters and the catch of 165 boats was inspected. 96 commercial skippers were interviewed and 230 had their catch inspected. Three aerial surveys of the entire area were conducted during which a total of 1067 shore fishers were counted giving a shore fisher density of 0.39 fishers.km⁻¹. The majority (99%) of participants in all sectors of the linefishery were male. The greatest number of participants were white, shore fishery 77% recreational ski-boat 98% commercial skiboat 89%, followed by coloured, asian and black people. To a large extent this reflects the income of various racial groups. Most fishers supported the current linefish management plan. However, when tested on their knowledge of the size limits, bag limits and closed seasons of their target species many shore fishers (59%) did not know them and a high proportion of fishers in all sectors had disobeyed at least one of the regulations (shore 50%, recreational ski-boat 70%, commercial ski-boat 56%). When compared to historical data the present catch per unit effort (CPUE) in all sectors has decreased. Most interviewees in the various sectors did not accept responsibility for the decline in CPUE, but attributed it to three principal reasons vis their perceived direct competitors, trawling and pollution. Analysis of the catch revealed that all sectors were multispecies fisheries, with each sector being characterised by a small number of target species. Catch composition differed significantly between the shore and ski-boat sectors, but there was significant overlap between the two skiboat sectors. Analysis of the catch in comparison to that reported to the National Marine Linefish System (NMLS) revealed that there was a substantial degree of under-reporting. There was little seasonal difference in effort in the shore fishery while the recreational ski-boat effort was highest in the summer and the commercial ski-boat effort was high in the winter. Effort in the shore and recreational ski-boat fisheries was concentrated over weekends while the commercial ski-boat effort was highest during weekdays. Total effort for the entire area was estimated at 903 186 (±1913) fisher days per annum in the shore fishery, 24 357 (±685) recreational ski-boat fisher days and 64 266 (±1686) commercial ski-boat fisher days.

▼ Climate variability can affect fish populations and fisheries production in numerous ways, including inducing measurable fluctuations in fish growth, condition, and fisheries production. Unfortunately, mechanisms driving these linkages are poorly understood for most exploited species, which hinders effective management. The purpose of this study was to use the Gulf Corvina (Cynoscion othonopterus), a heavily exploited marine fish in the Gulf of California, Mexico, as a model to investigate relationships between El Niño Southern Oscillation (ENSO) as measured by the Multivariate ENSO Index (MEI), sea surface temperature (SST), precipitation, drought as measured by the Palmer Drought Severity Index (PDSI), and river flow from the Morelos Dam with three parameters: adult fish condition, growth rate, and fisheries production. Adult fish condition was assessed by comparing annual variations in weight-length relationships of fish captured by the commercial fishery to each climate and environmental variable using an exponential model. Fish growth rate was measured using otolith chronologies for juveniles (years 0-2) and adult (years 3-10). Lastly, annual catch data from the commercial fishery was compared to each climate and environmental variable to examine relationships between climate and fisheries production. Results indicate that adult condition, juvenile growth rate and fisheries production are enhanced during El Niño conditions and increased SST. El Niño conditions during the birth year showed a positive relationship with fisheries landings at peak age of capture five years later, suggesting a possible linkage between juvenile recruitment, survivorship and future fisheries production. A weak positive relationship between river flow and growth rate in juveniles and adults was also found, which indicated that growth rate of both life history stages may be enhanced during strong El Niño years with high river flow. However, no relationship was found between precipitation and our parameters. Lastly, a positive relationship between decreased drought during the birth year and fisheries landings five years later indicated a freshwater influence on fisheries production. Our results indicate climate variability acting through El Niño events has a positive effect on growth, condition, fisheries production, and potentially juvenile recruitment suggesting the importance of both ocean climate variability and freshwater input on the Gulf Corvina.

▼ Predictive modeling can inform natural resource management by demonstrating stressor-response pathways and quantifying the effects on selected endpoints. This study develops a risk assessment model using the Bayesian network-relative risk model (BN-RRM) approach, and, for the first time, incorporates eukaryote environmental DNA data as a measure of benthic community structure into an ecological risk assessment context. Environmental DNA sampling is a relatively new technique for biodiversity measurements that involves extracting DNA from environmental samples, sequencing a region of the 18s rDNA gene, and matching the sequences to organisms. Using a network of probability distributions, the BN-RRM model predicts risk to water quality objectives and also the richness of benthic taxa in the Noosa, Pine, and Logan Estuaries in South East Queensland (SEQ), Australia. The model is more accurate at predicting Dissolved Oxygen than it is the Chlorophyll-a water quality endpoint, and it predicts photosynthesizing benthos more accurately than heterotrophs. Results of BN-RRM modeling indicate that the water quality and benthic assemblages of the Noosa are relatively homogenous across all sub risk regions, and that the Noosa has a high probability (73 - 92% probability) of achieving water quality objectives, which indicates low relative risk. On the other hand, the Middle Logan, Middle Pine, and Lower Pine regions are much less likely to meet objectives (15 – 55% probability), indicating a relatively high risk to water quality in those regions. The benthic community richness patterns associated with low relative risk in the Noosa are high Diatom relative richness and low Green Algae richness. The only benthic pattern consistently associated with high relative risk to water quality is the high Fungi richness state. The BN-RRM predicts current conditions in SEQ based on available monitoring data, and provides a basis for future predictions and adaptive management at the direction of resource managers. As new data are made available or more questions are asked, this BN-RRM model can be updated and improved.

▼ The Amazon, as the world's largest rainforest region, is important for global carbon cycle, climate change, and ecosystem. This dissertation aims to investigate rainfall variability and the related atmospheric and land processes in tropical South America using both observations and climate models. The first two studies concern the changes and variability of the dry season over the southern Amazon, a domain with vulnerable tropical rainforest. Ground-based observation from 1979 to 2011 indicates the dry season length (DSL) has increased at a rate of 6.5 ± 2.5 days per decade, mainly caused by a delay of the dry season ending (DSE). A delay of the DSE has a clear impact on fire counts in austral spring. Moreover, the DSE also has large interannual variation and thus has a strong impact on drought and flood. Three dry season conditions are crucial for determining its trend and interannual variation. (i) A poleward shift of the subtropical jet over South America (SJ[subscript SA]) can prevent cold frontal systems from moving northward into the Amazon. This delays cold air incursion and results in late DSE over. (ii) An anomalous anticyclonic center, which enhances westerly wind at 850 hPa (U850) and the South American Low Level Jets (SALLJs), leads to moisture export from the southern Amazon to La Plata basin and reduces convective systems that provide elevated diabatic heating. (iii) Smaller convective available potential energy (CAPE) and larger convective inhibition energy (CIN) limit local thermodynamically driven convection. However, global climate models can capture neither the drying trend nor the variability of the DSL and DSE. Thus, the third and fourth studies deal with understanding the reported systematic dry bias over the Amazon in climate models. Our evaluation of the Coupled Model Intercomparison Project phase 5 (CMIP5) models indicates the positive feedback between reduced cloudiness, too much surface solar radiation, high Bowen ratio, and suppression of rainfall appears to cause the dry bias. A further investigation on Geophysical Fluid Dynamics Laboratory (GFDL) models demonstrates the Amazon dry season dry bias origins from biases in complicated processes, highlights the importance of the northern Andes on moisture flux convergence over the Amazon in the dry season, and suggests using at least 1° atmosphere-only model to understand the remaining dry season dry bias. The fifth study proposed a new method to assess CMIP5 climate projections for rainfall extremes. The results indicate future heavy rainfall changes in the Amazon due to anthropogenic forcing may be underestimated by multi-model ensemble mean.

▼ Australian rivers are generally considered to have high flow variability with large differences between baseflow and flood flows as well as large differences in the volume of floods of various return periods. This comparative study systematically assesses the hydrology of Snowy Mountain rivers to determine whether snowmelt rivers demonstrate similar discharge characteristics to their non-snowmelt counterparts. Historical and current gauging data was used to investigate flood frequency and flow scaling relationships for unregulated alluvial and semi-alluvial rivers in eighteen Snowy Mountain rivers and fifteen temperate east coast and semi-arid non-snowmelt rivers. The results demonstrate that Snowy Mountain rivers do not exhibit the same hydrological variability as non-snowmelt rivers. By comparison, snowmelt rivers were found to have a strong seasonal discharge pattern and a higher baseflow index. The flash flood magnitude index for the snowmelt rivers (0.27) was lower than the global mean (0.28) and lower than the comparison east coast (0.74) and semi-arid (0.62) rivers. Snowy Mountain rivers demonstrated low inter-annual flow variability through low coefficient of variation values (0.38) that contrasted with those of the east coast (1.19) and semi-arid (1.41) rivers. These results were reflected by Snowy Mountain rivers having the flattest flood frequency ratio curves, the least vertical spread between predicted flow levels of varying average recurrence intervals within a given cross-section and less variability in event-based runoff coefficients. This has implications for unit-discharge relationships, which in turn affects the magnitude of flow scaling by catchment area. Floods were found to become proportionally larger (scaled to catchment area) at all recurrence intervals in Snowy Mountain rivers, but not to the extent that they did in comparison rivers. The drivers of the low inter-annual hydrological variability include a regular, seasonal climate with local conditions that keep the ground moist for months at a time. The baseflows in the Snowy Mountain rivers are higher than in the non-snowmelt settings which works to decrease the difference between mean daily and flood flow rates and volumes.

▼ The objective of this project was to determine if Galaxiella nigrostriata populations could belong to a metapopulation. Metapopulation theory describes how multiple populations with occasional connectivity are a ‘population of populations’. Some populations’ habitats have optimal conditions (source habitats), others experience regular extinctions (sink habitats). Connectivity allows repopulation of extinct or uninhabited habitats. Galaxiella nigrostriata occurred randomly in 11 seasonal wetlands in the Kemerton wetland complex in south-west Western Australia over a 16 year period. The wetlands did not appear to be connected. Around 70% of wetlands on the Swan Coastal Plain in south-west WA have been filled or degraded since European settlement around 180 years ago. Of those, seasonal wetlands are at most risk from degradation. Galaxiella nigrostriata mainly live in seasonal wetlands between Augusta and Albany and in three remnant populations on the Swan Coastal Plain. They are small freshwater fish (length), aestivate in moist wetland sediments when wetlands dry and live for about one year. Seasonal wetlands and G. nigrostriata are threatened by nutrient enrichment, salinity, introduced fish, landscape modification and changes to hydroperiod by groundwater abstraction and declining rainfall. Inundated wetlands that previously contained G. nigrostriata, and wetlands where they had not been recorded, were sampled throughout south-west WA. Fish and crayfish abundance was surveyed and water samples analysed on site and in a laboratory. Physical characteristics of each wetland and surrounding landscape were also recorded. Information about wetlands was analysed to determine if physico-chemical characteristics accounted for G. nigrostriata abundance or distribution between wetlands. Lentocorrals were then established in two Kemerton wetlands prior to inundation. They were sampled following inundation to determine how and where within a wetland G. nigrostriata entered the sediment to aestivate. Aestivation was examined to determine whether any physical features may be lacking which could inhibit population persistence. Galaxiella nigrostriata specimens from each population had morphological measurements and counts taken prior to tissue being removed for genetic analyses. Two mitochondrial DNA markers were used to investigate divergence and connectivity within and between populations and catchments. Most wetlands were small (mean 0.6 ha), had tannin-stained water and 41% vegetation cover. All wetlands exceeded guideline values for Fe and Zn and those near agricultural land exceeded guideline values for TN and TP. However, no physico-chemical water properties or habitat features impeded G. nigrostriata abundance or distribution between wetlands. Additionally, it was thought there may be a commensal relationship between G. nigrostriata and burrowing crayfish, with G. nigrostriata using burrows to enter the sediment. No relationship was found between G. nigrostriata, crayfish or their burrows, indicating an alternative way for…

▼ Since the study on the Port Alfred/Kenton-on-Sea/Boknes linefishery by Hecht and Tilney (1989) there have been substantive changes to the linefish management environment in South Africa. Using the Port Alfred linefishery as a model, the aim of this study was to evaluate the effectiveness of the linefish management regulations that were implemented by Marine and Coastal Management (MCM) since 1992, and to assess the behaviour and 'status' of the fishery in response to these changes. Changes to both the licensing structure and catch regulations have had a significant effect on the functioning of many aspects of the Port Alfred linefishery (fishing effort, catch composition, cpue) as well as on the structure of the fishery and its socio-economic profile. Overall commercial cpue decreased from 1985 to 1998. Since 1998 there has been a significant increase in cpue (from 2.3 Kg.fisher⁻¹ hour⁻¹ to a peak of 4.8 Kg.fisher⁻¹.hour⁻¹ in 2005. This was attributed to good catches of geelbek, particularly in 2005, 2007 and 2008 (during these years geelbek contributed an average of 35% to the total landings in comparison to a mean contribution of II % between 1985 and 2004). However, size spectra analysis suggests that the increase in overall cpue since 1998 misrepresents the actual status of the fishery. If geelbek is excluded from the analysis on the grounds that it is the only species in the fishery that is highly migratory, susceptible to recruitment fluctuations and it does not contribute to the catches on a year round basis, then the results suggest that the fishery is still in a declining phase despite the 80% reduction in commercial effort and numerous stricter catch regulations (e.g. size/bag limits). Furthermore, the cpue of silver kob, which has been the "mainstay" species of the fishery, has consistently declined over the last 23 year period (from 1.69 Kg.fisher⁻1 .hour1 in 1986 to 0.86 Kg.fisher⁻1.hour⁻1in 2007). The substantial reduction in commercial effort in the fishery from 33 vessels in 2001 to 13 in 2002 resulted in a shift from commercial to recreational fishing. The number of active commercial vessels in Port Alfred alone decreased from 29 in 1989 (Hecht 1993) to four in 2008. During the same timeframe, the number of regularly active recreational vessels had almost doubled (16 in 1989 to 26 in 2008). Despite the greater number of recreational boats in the fishery they only landed approximately half the average yearly tonnage of the commercial vessels (21,5 and 44,7 tonnes,annum-I , respectively) between 2006 and 2008, This was ascribed to the differences in catch regulations for the two sectors, Furthermore, it was speculated that increasing operating costs and narrowing profit margins have contributed to lower levels of compliance in both the commercial and recreational sectors since 2006, For example, 16% of silver kob landed during 2006-08 were under the minimum size, Despite the changes made to the regulations since 1998 and the 60,6% reduction In legislated commercial effort in the fishery between 2001…

▼ Assessment of trophic interactions between increasing populations of New Zealand fur seals (Arctocephalus forsteri) and fisheries in southern Australia is limited due to a lack of species specific demographic data and an understanding of the factors influencing population growth. To establish species specific demographic parameters a cross-sectional sample of New Zealand fur seal females (330) and males (100) were caught and individually-marked on Kangaroo Island, South Australia between 2000 and 2003. The seals were aged through examination of a postcanine tooth, which was removed from each animal to investigate age-specific life-history parameters. Annual formation of cementum layers was confirmed and accuracy in age estimation was determined by examination of teeth removed from individuals of known-age.Indirect methods of assessing reproductive maturity based on mammary teat characteristics indicated that females first gave birth between 4-8 years of age, with an average age at reproductive maturity of 5 years. Among reproductively mature females, age-specific reproductive rates increased rapidly between 4-7 years of age, reaching maximum rates of 70-81% between 8-13 years, and gradually decreased in older females. No females older than 22 years were recorded to pup. Age of first territory tenure in males ranged from 8-10 years. The oldest female and male were 25 and 19 years old, respectively. Post-weaning growth in females was monophasic, characterised by high growth rates in length and mass during the juvenile growth stage, followed by a gradual decline in growth rates after reproductive maturity.In contrast, growth in males was biphasic and displayed a secondary growth spurt in both length and mass, which coincided with sexual and social maturation, followed by a rapid decline in growth rates. Age-specific survival rates were high (0.823-0.953) among prime-age females (8-13yrs of age) and declined in older females. Relative change in annual pup production was strongly correlated with reproductive rates of prime-age females and adult female survival between breeding seasons.

Relações entre a variabilidade ambiental do ambiente pelágico oceânico e a distribuição e abundância relativa dos principais recursos pesqueiros oceânicos, vêm sendo avaliadas em diversos estudos, principalmente com a intensificação dos processos de mudanças climáticas, ocorridos em décadas recentes. O objetivo principal deste estudo foi avaliar a relação entre a captura (CPUE) da albacora branca (Thunnus alalunga) e algumas variáveis ambientais, juntamente com dados espaço-temporais da atividade pesqueira, referentes ao período compreendido entre 1980 e 2007. Os dados de pesca utilizados, incluindo a distribuição espaço-temporal do esforço de pesca e das capturas, são referentes à operação da frota espinheleira do Brasil (Banco Nacional da Pesca de Atuns e Afins) e de China Taipei (International Comission for Conservation of Atlantic Tunas, em inglês). Os dados ambientais (TSM Temperatura da Superfície do Mar e PCM Profundidade da Camada Mistura) foram obtidos de bancos internacionais de dados oceanográficos. Modelos Aditivos Generalizados (GAMs) foram utilizados para averiguar as relações entre o rendimento pesqueiro, expresso através da CPUE (variável dependente), e à variabilidade ambiental. Além disto, aspectos espaço-temporais (latitude, longitude, mês e ano) foram incorporados, de modo a evidenciar a sazonalidade das capturas na área do estudo. Os resultados obtidos mostram que à variabilidade ambiental do ambiente oceanográfico influencia fortemente à distribuição e abundância da espécie e, consequentemente, das capturas. A TSM (correlação positiva com a latitude, para a área de estudo) foi o fator ambiental que mais influenciou a CPUE. Além disto, podemos inferir que as capturas sofrem influência positiva em áreas com a termoclina mais próxima da superfície aquática e que existe um padrão sazonal de distribuição e abundância bem marcado. Estes aspectos parecem estar relacionados com o padrão migratório da espécie no Atlântico sul, incluindo a concentração da mesma ao largo da costa brasileira para fins reprodutivos, durante o verão austral.

Analysis between the environmental variability in the pelagic ocean environment, distribution and abundance of the main oceanic fishing resources, have been evaluated in several studies, mainly with the intensification of global climate changes in the recent decades. The main objective of this study was to evaluate the relations between the catches (CPUE) of albacore(Thunnus alalunga) and some environmental parameters, together with spatio temporal data of fishing activities during the period between 1980 and 2007. The fishing data used, including the spatio temporal distribution of effort and catches are referred of long line fleet operations of Brazil (BNDA) and China Taipei (ICCAT). The environmental parameters (SST Sea Surface Temperature and DML Depth Mixed Layer) were obtained in international oceanographic data banks. Generalized Additive Models (GAMs) were used for analyses between CPUE (dependent variable) and the environmental variability. Furthermore, spatio…
