Partial fish meal replacement by soy protein concentrate, squid and algal meals in low fish-oil diets containing Schizochytrium limacinum for longfin yellowtail Seriola rivoliana

It is shown that FM can be substantially reduced using blends of SPC, squid and algal meals in diets for longfin yellowtail with no significant effect on fish growth and intestinal tissue integrity. The results contribute to the knowledge to improve the sustainability of aquafeeds by using blends of terrestrial and aquatic plant ingredients.
