Hormonal regulation of the onset of puberty in striped bass, Morone saxatilis

Principal Investigator:

Yonathan Zohar

Start/End Year:

1995 - 1999

Institution:

Center of Marine Biotechnology, University of Maryland Biotechnology Institute

Topic(s):

Aquaculture

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.

Exploring the Use of Benthic Microbial Fuel Cells to Remove Sulfide While Harvesting Energy from Oyster Aquaculture Biodeposits

Oyster aquaculture is a rapidly growing industry in Maryland’s Chesapeake waters which stimulates economic activity and may provide a host of ecosystem benefits. A potential concern associated with the intensification of the oyster aquaculture is the local production and accumulation of oyster biodeposits, which can lead to a porewater sulfide accumulation and declining bioturbation, symptoms of declining ecosystem function. Sulfide is naturally removed from the seafloor by the interactions between bioturbating infauna and sulfide oxidizing bacteria.
