Current Research Interests and Subject Areas Available for Graduate Research
My current research interests are in fish culture with particular emphasis on reproductive biology. Management of reproduction is an important aspect of aquaculture, as many fishes of economic importance do not reproduce away from their natural habitat; therefore, spawning must be accomplished through induced means. A related consideration for some fishes is that reproduction may be unwanted and control is desirable. Examples include introduction of exotic species or excessive recruitment in production ponds which adversely affects individual growth. These problems have been addressed through hormone-controlled spawning, steroid-induced sex reversal, interspecific hybridization, and chromosome manipulation at fertilization. These research activities have included four species of Chinese carps, several species of tilapia, and common carp, all of which are exotic fishes; native species include striped bass, channel catfish, largemouth bass, paddlefish, and sturgeon.
I have been active in more general fishery biology investigations, particularly reservoir and large river fisheries, including the evaluation of sampling techniques. Emphasis has been on predator/prey and growth relationships involving striped bass and largemouth bass with shads and bluegill.
