Evaluating the Effects of Fermented and Non-Fermented Cottonseed Flour on Growth Performance of Juvenile Red Drum Sciaenops Ocellatus and Hybrid Striped Bass Morone Chrysops × M. Saxatilis
There continues to be a pressing need to develop alternative protein feedstuffs to reduce dependence on fishmeal (FM) and other costly ingredients and thereby increase the sustainability and potential expansion of global aquaculture. In this study, three feeding trials were conducted to evaluate the...

There continues to be a pressing need to develop alternative protein feedstuffs to reduce dependence on fishmeal (FM) and other costly ingredients and thereby increase the sustainability and potential expansion of global aquaculture.
