Environmental drivers of the abundance and distribution of forage fishes on the Northeast US shelf, with a particular emphasis on northern sand lance
Small pelagic fishes, also termed forage fishes, represent a critical link between secondary production and myriad top predators in marine ecosystems, including the Northeast US shelf. In this dissertation, I analyze the drivers of forage fish distribution throughout the Northeast US shelf and the …

Vertical Distributions of Zooplankton at the Mouth of Chesapeake Bay and Calibration of Backscatter From an Acoustic Doppler Current Profiler
<p>This study investigated the physical factors influencing the vertical distribution of zooplankton at the mouth of the Chesapeake Bay and attempted to derive biological data from acoustic Doppler current profiler (ADCP) backscatter. A single site was occupied in the North Channel at the mouth of …

Modeling Environmental Effects on MSX Prevalence and Intensity in Eastern Oyster (<i>Crassostrea virginica</i>) Populations
<p>An oyster population model coupled with a model for Haplosporidium nelsoni, the causative agent of the oyster disease MSX, was used with salinity time-series constructed from Delaware River flow measurements to study environmentally-induced variations in the annual cycle of this disease. …

A Model of the Population Dynamics of the Blue Crab in Chesapeake Bay
… has particular application to the blue crab fisheries in Chesapeake Bay, an economically important industry whose successful management has been hindered by relatively poor understanding of the population dynamics. Recent biological studies have indicated a systematic spawning behavior which …

Determinants for the Timing of Escapement From the Sockeye Salmon Fishery of the Copper River, Alaska: A Simulation Model
<p>A model to estimate determinants for migratory timing of catch and escapement in a terminal salmon fishery is presented. A method was developed to estimate average seasonal migration rates of salmon through a harvest area from catch and escapement data. The time series for the total population …

An Examination of the Variability of Migratory Timing Statistics Estimated From Catch and Effort Observations
<p>The estimate of the mean arrival time based on catch or CPUE of fishes migrating into a fixed harvest area is a function of the number of days fished. Simulation studies using chinook salmon catch and effort data from the Yukon River delta, Alaska indicate that fishing effort concentrated at the …

Growth Potential of Young Black Sea Bass, Centropristis Striata, in Artificial Environments
<p>The growth potential of the commercially important marine finfish, black sea bass (Centropristis striata), was examined for aquaculture under controlled conditions. The effect of food and body weight on growth was evaluated using juveniles and young black sea bass cultured with a natural diet …
