1995 - 1999

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.
