▼ Rockfish (genus Sebastes) are ovoviviparous with pelagic larvae that may travel great distances before settling on shallow reefs where they become substrate-dependent juveniles. Artificial reefs can be used to monitor juvenile recruitment by providing settlement habitat. Juvenile recruitment in this context refers to the onshore delivery of juveniles from pelagic larval habitats to nearshore reefs. In this study, submerged artificial reefs, Standard Monitoring Units for the Recruitment of Fishes, SMURFS, were used to examine juvenile rockfish recruitment in northern California. Two SMURFs were deployed in Trinidad Bay, California, between June and September of 2010 and 2011. SMURFs were fished on a weekly basis. The objectives of the study were to 1) determine the effectiveness of using SMURFs to examine juvenile rockfish recruitment in northern California, 2) provide a baseline description of the abundance, diversity and succession of all species sampled, 3) compare the physical oceanographic conditions between 2010 and 2011, and 4) analyze the relationships between rockfish abundance and physical parameters within and between each field season. The SMURFs deployed in Trinidad Bay, California, provided suitable settlement habitat for juvenile fish. In total, nine species of fish, representing five families, recruited to SMURFs over the duration of the study. Species sampled included: northern clingfish (Gobiesox maeandricus), black rockfish (Sebastes melanops), copper rockfish (Sebastes caurinus), redbanded rockfish (Sebastes babcocki), bocaccio (Sebastes paucispinis), kelp greenling (Hexagrammos decagrammus), cabezon (Scorpaenicthyes marmoratus), fluffy sculpin (Oligocottus snyderi), and penpoint gunnel (Apodicthyes falvidus). In addition to these species, it is possible small numbers of gopher rockfish (Sebastes carnatus), and black-and-yellow rockfish (Sebastes chrysomelas), were also sampled. Due to similar juvenile morphologies, these two species were grouped together with copper rockfish and considered the CGBY rockfish complex. The abundance of fish varied between the years with 3,657 fish sampled during 2010, and 471 fish sampled during 2011. The majority of fish collected, 87%, were either CGBY or black rockfish. Fish moved onshore in relation to their parturition date. Inter-annual comparisons were limited due to the short duration of the study. However, 2010 was characterized by having cooler sea surface temperatures. This implies that cooler water temperatures may promote stronger recruitment years. At the same time, no physical parameters were able to describe the within year variation of weekly abundance. Based on this study, it is recommended that Trinidad Bay, California, be used as a site for monitoring juvenile rockfish via SMURFs. Continuing to collect data regarding the recruitment of juveniles to nearshore reefs may improve the accuracy of predicting future adult stock sizes. This could lead to proactive management strategies that can be tailored to local populations. Furthermore,… Advisors/Committee Members: Mulligan, Timothy James.

▼ Processes that regulate common carp (Cyprinus carpio) recruitment (i.e. survival of eggs, larvae and juveniles) are largely unknown. In interconnected lake-marsh systems of Minnesota, young of year (YOY) carp are generally found in marshes that winterkill and lack bluegill sunfish (Lepomis macrochirus), an abundant native predator. This suggests that bluegills might function as a biocontrol agent for carp. Further, whereas YOY carp are commonly found in winterkill marshes of south-central Minnesota, they are not found in similar systems in northern Minnesota where lake productivity is much lower, suggesting an aquatic productivity bottleneck on carp recruitment. Finally, in marshes where carp recruit (productive and bluegill-free), YOY must disperse into adjacent lakes to drive high population abundance. In this study, I conducted three experiments to test 1) the effect of bluegills on carp recruitment; 2) the effect of aquatic productivity on larval carp survival, growth and diet; 3) natural dispersal tendencies of YOY carp from a marsh into an adjacent lake. The first experiment employed four (20 m diameter) impermeable enclosures from 2011-2014. Each year, enclosures were stocked with carp eggs and every other one was stocked with bluegills. Backpack electrofishing surveys conducted five weeks later showed that carp catch per unit of effort (CPUE) was over 10-fold lower in the enclosures stocked with bluegills than in the controls. The second experiment, conducted in 2014 and 2015 used aquaria stocked with carp larvae and supplied with zooplankton densities and community structures from lakes of three different trophic states (oligo-, meso-, and eutrophic). It showed that carp larvae selectively consumed macrozooplankton (> 200 μm) and their growth rates were highest in the eutrophic lake and lowest in the oligotrophic lake. Survival, however, was high in all treatments. The third study was conducted in a natural lake-marsh system and utilized passive integrated transponder (PIT) tags to quantify the outmigration of YOY carp from the marsh to the lake. It showed that < 6% YOY carp outmigrated to the lake, supporting previous indirect estimates. The results of these three studies are important to understanding recruitment dynamics of carp in lake-marsh systems in Minnesota.

▼ The recruitment, growth rate and survival of every juvenile corals on artificial substrates, deployed every 2 months since September 1998, for a total of 6 times, were investigated every 2 months, from November 1998 to September 2000, at Nanwan, southern Taiwan. The influence of season and habitat (e.g., new vs. old substrate and different positions etc.) on the above life history characteristics were the foci of this study. Coral recruitment during the 2-year period was low, averaging 1.3 recruits per 15x15 cm PVC plate; it was dominated by Pocilloporidae (50.7%) and Poritidae (31.9%), with Stylocoeniella guentheri (6.2%), Anthelia flava (5.1%) and Acropora sp. (2.4%) and others as minor constituents. Seasonal variations of new recruit densities were significant on new substrates of 2-months old, but not on old substrates of 14-month old. Pocilloporidae, for example, had the highest new recruit densities in May 1999; although the survival rate in this period, cumulative survivorship and growth rate were lower than those settled in other times. New recruit densities on new substrates were significantly higher than that on old substrates, but the survival rates of new recruits in the first 2 months were not significantly different between new and old substrates. The cumulative suvivorship and the initial juvenile growth rate of Pocilloporidae were higher on new than on old substrates. New recruit density of Pocilloporidae was higher in 1999 than in 2000, with an opposite pattern found in Poritidae. Juveniles prefer to settle on new substrates higher than old substrates and recruit densities decrease as plate age in Pocilloporidae, but an opposite pattern was found in Poritidae. The Pocilloporidae had relatively higher recruit densities but lower cumulative survivorship than Acropora sp. and Stylocoeniella. guentheri. A margin effect on the PVC plates was found, with higher new recruit densities and growth rates in the margin than in the intermediate and the inner region. The survival rate and the cumulative survivorship of recruits, however, were similar among the 3 regions on the plates. Thus the pattern of margin effect on the plate is unlikely a result of active larva preference. Among the scleractinian recruits, Acropora sp. had the highest growth rate, averaging 1.8 mm/month in maximum diameter. Within Pocilloporidae, the maximum diameters of juvenile Seriatopora hystrix was significant smaller than Pocillopora damicornis from 2-12 month. Some recruits of Seriatopora hystrix did not grow for more than a year. The overall cumulative survivorship of coral recruits was low at Nanwan, with 29.2% surviving the first year, and 0.7% surviving 2 years. Within dead juveniles, 65.7% was caused by disappearance and 34.3% was caused by algae, sediment and others organism etc. The relationship between size and mortality on juvenile Pocilloporidae is significant, implying that larger colony corals have higher survivor chance than smaller colony corals.

▼ Over the past three decades recruitment of European eel (Anguilla anguilla L.) to inland waters has declined by more than 95%. The causes of this decline are still unclear although a number of factors are thought to have a contributory effect including pollution, habitat loss, climatic changes in the ocean, overfishing and the spread of non-indigenous parasites and disease. In this study, undertaken from 2008 to 2010, the abundance, timing and seasonal duration of eel recruitment was investigated on the Shannon, Erne and Lee river systems, where the natural connectivity of these rivers is interrupted by hydroelectric dams and regulating weirs. Catches of juvenile eels at fixed traps downstream of these structures were monitored and the length, weight and age of eels sampled were analysed. Total catch varied between years at each site and were generally low. The timing of the migration showed considerable interannual variability as well as differences between sites. Mean eel length was greater for eels trapped further upstream from the tidal limit of estuaries. At the Parteen regulating weir on the River Shannon variation in the juvenile eel catch was analysed in relation to environmental factors using multiple regression appropriate to time series data. Factors included in the regression model which explained a statistically significant portion of the variation in juvenile eel catch were: day length, flow, water temperature, moon fullness and year. An exceptional peak in the eel catch was recorded in August 2008 following very heavy rainfall. The catch recorded during August 2008 accounted for 51% of the total catch for the period 2008 to 2010. Juvenile eels sampled at fixed traps were examined for the presence of Anguillicoloides crassus, an introduced Asian parasitic nematode of eels that can affect swimbladder function. Investigations on the infection levels in yellow and silver eels are frequently reported but there is a paucity of information regarding infection of juvenile eels. Prevalence and intensity of infection was determined. Relationships between host length and condition and the infection intensity were also investigated. Juvenile eels sampled from the River Lee (N = 73) were found to be uninfected. Prevalence recorded for a sample from the Erne (N = 44) was 14% and mean intensity of infection was 1.0. On the River Shannon, samples (N = 498) were collected at the Ardnacrusha dam and Parteen regulating weir during 2008, 2009 and 2010. At Ardnacrusha elvers were more frequent in the trap catch and mean prevalence ranged from 23-66% with mean intensity ranging from 1.35 to 1.94. At Parteen, where larger juvenile eels are predominant in the trap catch, mean prevalence ranged from 59-66% and mean intensity ranged from 1.90 to 2.00. There was no significant correlation between the number of Anguillicoloides present and the condition factor of the eels sampled. Anguillicoloides infection of migrating juvenile eels used for stocking represents a mechanism of dispersal for the parasite to… Advisors/Committee Members: McCarthy, Thomas K (advisor).

▼ The hydrothermal vent environment, in its extreme spatial and temporal variability, offers the opportunity to study habitats that are naturally fragmented and unstable. The vestimentiferan tubeworm Ridgeia piscesae is a foundation species inhabiting hydrothermal vent habitat in the Northeast Pacific Ocean. R. piscesae is a phenotypically plastic species and is arranged in a metapopulation spatial structure, with each local population displaying one of a range of morphotypes. Ridgeia piscesae participates in an obligate symbiosis that is dependent on hydrogen sulphide in the hydrothermal vent fluid that supplies each local population. Hydrothermal fluid flow is highly variable in the hydrothermal vent environment and hydrogen sulphide flux is a limiting nutrient for R. piscesae; this variability may create differences in habitat quality. The objective of this study is to determine whether local populations of R. piscesae centered on high and low flux hydrothermal fluid outputs are similar in body condition, reproductive condition, and juvenile recruitment. Using the submersibles ROPOS and Alvin, I collected high flux and low flux sample pairs from within meters of each other at multiple sample sites on Axial Seamount and the Endeavour segment of the Juan de Fuca Ridge. I used morphological measurements, histology and lipid analysis to assess physiological and reproductive condition. I also determined the relative abundances of new and older recruits in high and low flux local populations. I found that low flux habitat was inferior in its ability to support Ridgeia piscesae at all stages in the tubeworm’s life cycle. In terms of body condition, local populations in low flux habitat had lower body weight, greater body length, smaller anterior tube diameter, lower trophosome volume, lower total lipid volume, and lower branchial plume condition. With respect to reproductive condition, local populations in low flux habitat had lower proportions of reproductive individuals, less sperm transfer, lower gonad volume, and fewer mature oocytes; there was no difference in sperm development stages between high and low flux habitat. From the perspective of the individual, low flux tubeworms live longer, and lifetime reproductive output may be comparable to high flux tubeworms. However, turnover is higher in the high flux habitat, so reproductive output of high flux populations is greater than that of low flux populations. Juvenile recruitment was biased toward high flux habitat, although this trend was not significant and recruitment to low flux habitat was still notable. The differences between reproductive output and juvenile recruitment between these habitats support a source-sink model of population dynamics. From the perspective of the metapopulation, low flux habitat is inferior in its ability to support Ridgeia piscesae at all stages in the tubeworm’s life cycle. This distribution of relative contributions to the overall population of a key species in a Marine Protected Area (MPA) should factor into management decisions… Advisors/Committee Members: Tunnicliffe, Verena (supervisor).

▼ Two closely-related, different-sized species of geese nest sympatrically south of the Queen Maud Gulf (QMG) in Canada’s central arctic. Following a period of high population growth rate in both species within the QMG, the population growth rate of larger-bodied lesser snow geese (Chen caerulescens caerulescens; hereafter snow geese) has slowed most recently to roughly half that observed in smaller-bodied Ross’s geese (Chen rossii). I focused on factors that influence productivity and recruitment in these two species, to improve our understanding of life history variation associated with interspecific differences in body size, and to test for density-dependent population responses. I used long-term data (1991 to 2008) to compare spring nutrient reserves, breeding strategies, clutch sizes, nest success, and juvenile survival in Ross’s and snow geese breeding at Karrak Lake, Nunavut; a large breeding colony located within the QMG. Long-term patterns of spring body condition (i.e., fat and protein reserves) diverged in prospective breeding female Ross’s and snow geese implying that differences in food acquisition ability had become more acute. Snow geese displayed larger reductions in protein and fat reserves through time compared to Ross’s geese thereby suggesting a differential density-dependent response in the ability to store nutrient reserves, a prerequisite for breeding in both species. Decreased per capita food availability influenced the timing of reproduction in both species. Nesting phenologies of Ross’s and snow geese, adjusted for variation in phenology of local spring climate, have become later by 6.5 and 5.0 days, respectively, since 1991. Nutritional strategies (i.e., reliance on reserves versus local food) used for clutch formation differed between species. Ross’s geese displayed greater reliance on stored reserves (i.e., capital breeding) than did snow geese, though both used endogenous reserves (> 62% of yolk protein, > 48% of albumen, and > 73% of yolk lipid) for clutch formation. Ross’s and snow geese experienced declines of 28% and 23% in body masses from arrival to post-laying and also until hatch demonstrating that endogenous reserves are the main nutrient sources for incubation. Still, constraints of small size forced Ross’s geese to use a mixture of local food plants and reserves for incubation metabolism. I then examined differences in clutch size, nest success, and juvenile survival to understand of the role of recruitment in the interspecific divergence of population trajectories. I did not find strong interspecific differences in clutch size and nest success. Overall, snow geese had a larger mean clutch size, which was expected based on benefits of a larger-body size. Clutch sizes decreased with delays in breeding and decreasing protein reserves of arriving females, although Ross’s geese displayed larger declines with decreasing protein reserves. Mean apparent nest success for Ross’s geese was 4.5% higher compared to snow geese. Nest success showed large declines (11%) in both species… Advisors/Committee Members: Alisauskas, Ray T., Schmutz, Joel A., Chivers, Douglas P., Messier, Francois, Machin, Karen L., Clark, Robert G..

▼ Genetic variation was examined in two endangered mussel species, Epioblasma brevidens and E. capsaeformis, and a common species Lampsilis fasciola, in the Clinch River, TN, by screening mitochondrial DNA (mtDNA) sequences and nuclear DNA microsatellites. These species use fish hosts with varying dispersal capabilities, ranging from low, moderate, and high, respectively. Patterns of mtDNA polymorphism exhibited different trends for long-term population sizes for each species during the Holocene (~10,000 ya to present); namely, E. brevidens has declined over time, E. capsaeformis has remained stable, and L. fasciola has expanded. Long-term effective population size (Ne) was smallest in E. brevidens, intermediate in E. capsaeformis, and highest in L. fasciola. Moderately diverged mtDNA lineages, perhaps indicative of secondary contact, were observed in E. brevidens and E. capsaeformis. High levels of gene flow (Nm) were estimated among demes of L. fasciola using traditional F-statistics and likelihood estimates of Nm, whereas such metrics were lower in E. brevidens and E. capsaeformis. Data are consistent with population dynamics and life history traits of each species and their fish hosts. Age, shell growth, and population demography of Epioblasma brevidens, E. capsaeformis, and Lampsilis fasciola were studied from 2004-2007 in a 32-km reach of the Clinch River, TN. Observed maximum age and length of E. brevidens was 28 y and 71.5 mm for males and 11 y and 56.6 mm for females; of E. capsaeformis, 12 y and 54.6 mm for males and 9 y and 48.6 mm for females; and of L. fasciola, 45 y and 91.3 mm for males and 13 y and 62.6 mm for females. For all three species, observed maximum age and length was greater among males than females. Estimated population size in this river reach was approximately 43,000 individuals for E. brevidens, 579,000 individuals for E. capsaeformis, and 30,000 individuals for L. fasciola. Mean recruitment y-1 of 1 y-old E. brevidens ranged from 7.1% to 20%, of E. capsaeformis from 4.0% to 32.4%, and of L. fasciola from 5.8% to 25.6%. Population growth rate y-1 was 24.9% for E. brevidens, 34.6% for E. capsaeformis, and -22.4% for L. fasciola. Mortality rates of females were higher than for males of E. capsaeformis and L. fasciola, but not E. brevidens. Juvenile mussels were collected but temporally and spatially variable in occurrence, and a significant component of the age-class structure of all three species. Recruitment was very high during 2006-2007 for E. capsaeformis and other species, likely due to low river discharges in the spring-summer of 2005-2007. Surplus individuals of E. brevidens and E. capsaeformis are currently available to conduct translocations for restoration purposes. Population modeling of Epioblasma brevidens and E. capsaeformis in the Clinch River was conducted to determine suitable harvest levels for translocation of sub-adults and adults, and to determine quantitative criteria for evaluating performance and recovery of extant and reintroduced populations.
