The ultimate goal of the project will be to advance practical diet development for this white seabass (WSB). This is important for both the culture of this species for stock enhancement as well as the great potential to expand the culture of this species commercially. The specific objectives of this research will be to: 1) Evaluate the response of WSB to a modification of the existing commercial diet being feed to WSB, 2) Evaluate the response of WSB to a diet with increasing levels of soy protein concentrate, 3) Evaluate the response of WSB to a diet with increasing levels of soy oil as a fish oil replacement.
