Nutritional condition is a valuable metric in ecosystem-based fisheries management. However, the need for lethal sampling for the most accurate indicators ethically and logistically limits sample sizes. Percent moisture has been recommended for management of Striped Bass Morone saxatilis. We sought to develop bioelectrical impedance analysis (BIA) models for five size-classes of Striped Bass across three temperatures in a controlled laboratory setting. Results suggest that BIA is an accurate and robust method for estimating percent dry weight in Striped Bass, with model adjusted R-2 values in the range of 0.70-0.89. Temperature correction models successfully removed a significant relationship (P < 0.0001) between temperature and BIA model residuals (P = 0.48). We recommend that these models be tested with independent data collected in a field setting.

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.
