My research primarily focuses on improving the culture of commercially important finfish species by understanding and ultimately controlling physiological processes. Much of my research has focused on understanding reproductive processes, as this is requisite for successful propagation of aquatic species and often limits production. Fishes exhibit an astonishing array of reproductive strategies and each species' unique strategy must be unraveled before successful culture can be realized. Some of the specific topics which are of interest to me include the endocrine control of sex differentiation, factors that influence egg development and quality, effects of social interaction and environmental conditions on sex change (sequential hermaphroditism) and environmental control of reproductive cycles. Study of the life cycles of wild fish is often necessary to understand these processes. My students and I are also studying environmental conditions that minimize stress and optimize growth of cultured fish, such as salinity levels, light intensity, tank densities and temperature. We utilize applied aspects of aquaculture, such as hormonal induction of spawning, as well as modern laboratory techniques to address these questions.

Some of the species I have worked with in the past include summer flounder, alewives, blueback herring and Atlantic cod. Currently, my colleagues and I are investigating the aquaculture potential of black sea bass, a highly sought species in the upscale restaurant trade. As this fish is a protogynous hermaphrodite, changing from female to male, and is extremely fragile during its larval stage, we have many interesting problems to address before widespread commercial production is realized.

Some additional research projects in my lab include the culture and conservation of rainbow smelt, strain evaluation of striped bass for growth stress responsiveness and assessing the northeastern stock structure of migratory striped bass.
