Plant protein sources in the diets of the sciaenids red drum (Sciaenops ocellatus) and shortfin corvina (Cynoscion parvipinnis): A comparative study

The present manuscript provided an excellent opportunity to conduct comparative nutrition research and advance the development of more sustainable diets for the aquaculture of sciaenid species. For red drum, Sciaenops ocellatus, it was observed that Soybean meal (SBM) and soybean protein concentrate (Soy-PC) can replace up to 75% of fishmeal protein in the diet; while corn protein concentrate (Corn-PC) can successfully replace up to 50% of fishmeal protein, without compromising fish growth performance. For shortfin corvina, Cynoscion parvipinnis, Soy-PC and Corn-PC can replace up to 75% of fishmeal protein in the diet, while SBM successfully replaced up to 50% of fishmeal protein.
