Selected Current Projects

(1) Characterizing the blue crab spawning stock. Although much is known about the iconic blue crab, Callinectes sapidus, we know surprisingly little about the location and composition of the female spawning stock in most states. With this interdisciplinary project, I am working with a variety of colleagues to define what constitutes "spawning habitat", identifying spawning locations, characterizing the composition of the spawning stock, determining where spawners migrated from, and developing models to determine how the stock might respond to changes in management or environmental conditions.

(2) Establishing run counts for river herring in Chesapeake Bay. River herring, including the alewife Alosa pseudoharengus and blueback herring Alosa aestivalis, have declined dramatically in the last decade and are the focus of extensive conservation efforts. Spending much of their time in the ocean, they migrate back to freshwater streams on the Atlantic coast of North America to spawn. We are addressing a significant data gap, the lack of scientific spawning run counts in Chesapeake Bay, by developing methods to conduct counts using multi-beam imaging sonar.

(3) Use of acoustic telemetry to study fish behavior. With colleagues at NOAA's Gray's Reef National Marine Sactuary and Savannah State University, I am studying the behavior of gag grouper, scamp, and red snapper using acoustic telemetry. An important focus of this project is distinguishing behavior from the effects of the environment on sound transmission.
