Variability in red snapper otolith microchemistry among Gulf of Mexico regions
… The two objectives of this study were to apply otolith nursery chemical signatures to estimate red snapper mixing dynamics in the western Gulf, and to determine if signatures based upon trace metals associated with oil and gas platforms could discriminate between region and habitat of origin to …

Relating Water and Otolith Chemistry in Chesapeake Bay, and Their Potential to Identify Essential Seagrass Habitats for Juveniles of an Estuarine-Dependent Fish, Spotted Seatrout (<i>Cynoscion nebulosus</i>)
… the habitat-specific natural tags contained in otoliths. To this aim I investigated the variability in the chemistry of surface waters and otoliths of juvenile spotted seatrout, <em>Cynoscion nebulosus</em>, in five seagrass habitats of Chesapeake Bay, namely: Potomac, Rappahannock, York, …

The Importance of Thermal Habitat Quality for Pumpkinseed (Centrarchidae: Lepomis gibbosus) in Small and Constructed Coastal Embayments Along the Northwest Shoreline of Lake Ontario
… movement from warmer to cooler embayments. Using otolith microchemistry to identify natal embayments of fish, I confirm that age-0 and age-1 pumpkinseed, as well as age-0 largemouth bass (Micropterus salmoides) and age-0 yellow perch (Perca flavescens), exist in metapopulations. Embayment …

Maturation, Fecundity, and Spawning Frequency of the Albemarle/Roanoke Striped Bass Stock
… since their study and in recent years, otolith microchemistry with concentrations of elements such as strontium (⁸⁸Sr) has been used to determine movement and migration of different species to delineate movement from freshwater to more saline environments. The objectives of this study …

Survival, Abundance, and Relative Predation of Wild Rainbow Trout in the Deerfield Reservoir System, South Dakota
… evaluate the use of stable isotope analysis and otolith microchemistry for the classification of wild and hatchery Rainbow Trout origins. Juvenile Rainbow Trout were not found in the diets of Rock Bass Ambloplites rupestris, Yellow Perch Perca flavescens, and adult (>200 mm) Rainbow Trout in …

Ecology, Growth, and Migration of Pseudoplatystoma fasciatum in the Amazon Basin
… of the catfish P. fasciatum. Finally, I used otolith microchemistry to understand the migration ecology of P. fasciatum in the Amazon Basin. I found an inverse relationship between increment width in fish hard parts and hydrological indices. I also found that growth of P. fasciatum was no …

The Contribution of Missouri River Reservoir Side-Channel and Floodplain Habitats to Mainstem Fish Populations: The Effects of Losing Connectivity Between Hipple Lake and Lake Sharpe
… and adult contribution to Lake Sharpe’s fishery, otolith microchemistry was used to quantify fish movement and natal origins. This data will be used to inform management decisions regarding restoring Hipple Lake’s connectivity to the main channel. Water trace element chemistry (e.g., Sr:Ca, Ba:Ca) …

Spatial structuring and patterns of connectivity among Antarctic toothfish (Dissostichus mawsoni) stocks in the Southern Ocean: a view through otolith chemistry
… populations. To that end, this study used fish otoliths (ear bones) and laser ablation inductively coupled mass spectrometry (LA-ICP-MS) to determine life history aspects of Antarctic toothfish. The first research chapter (Chapter 2) tests the efficacy of otolith microchemistry techniques by …
