Evaluate photothermal manipulation and hormonal stimulation to induce off-season spawning of Morone sp. Evaluate the effects of stocking density, feeds and feeding strategies, and environmental conditions on survival and growth of hybrid striped bass and fingerlings in tanks/ponds. Characterize the physiological stress response to production practices with respect to environmental, nutritional, and genetic factors. Characterize gender-related production characteristics and develop methods of sex reversal to produce monosex populations. Determine conditions that increase growth-promoting actions of growth factors such as growth hormone, and insulin-like growth factors. Determine the nutrient digestibility of traditional and alternative feed ingredients to replace fish meal. Determine or refine nutrient requirements for different life stages and production systems. Use phenotypic and genotypic characters to evaluate new strains for economically revelant traits. Identify phenotypic and molecular differences among stocks of white/striped bass. Implement a selective breeding program to produce progeny with desired traits. Develop molecular markers for economically relevant traits to aid selective breeding efforts.
