Yellowtails from the genus Seriola are carnivorous
fish reared primarily in net cages and fed either fresh fish or pelleted
diets high in FM and FO (Nakada, 2008). Yellowtail culture would benefit
greatly from identification of alternative ingredients or ingredient
blends that can effectively spare or replace dietary FM and FO. Thus,
the aim of this study was to evaluate the use of soy protein concentrate
(SPC) and algalmeals to partially replace FMin low-FO diets for longfin
yellowtail in the context of fish growth, feed utilization, fillet fatty acid
composition, and intestinal cell and tissue integrity
