Description:
We propose to examine how dissolved oxygen concentrations and the spatial patterning of dissolved oxygen, water temperature and predation and prey abundances interact to affect the consumption, growth, production and recruitment of important fishes in the Chesapeake Bay. Research will focus on key piscivores (striped bass, bluefish, weakfish) and planktivores (Atlantic menhaden, bay anchovy). Spatially-explicit models will be used to compare patterns of growth and consumption relative to changes in habitat structure, prey abundances and spatial heterogeneity in the environment. Model simulations will address specific management questions dealing with the interrelationships of fish production and water quality.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
