Description:
The overall objective of the proposed research is to understand the endocrine mechanism regulating the onset of puberty in fish, using striped bass as a model, with a view towards developing techniques for accelerating or inhibiting puberty in farmed fish. This objective will be obtained through the following steps: study the ontogeny of the brain-pituitary gonadal (BPG) function prior to and throughout puberty study the ontogeny of the responsiveness of BPG axis to exogenous hormones induction of advanced (precocious) complete gametogenesis leading to spawning of good-quality eggs.

Featured Fellow
Nina Santos is a Ph.D. student at the Chesapeake Biological Laboratory at the University of Maryland Center for Environmental Science. For her dissertation, she is focused on small shrimp-like crustaceans called mysids – an understudied yet important part of many estuarine and coastal food webs.

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.
