The effects of diet treatment on fish growth, feed utilization, body proximate composition, nutrient
retention, fillet fatty composition, and intestinal integrity were evaluated. Growth rate and feed conversion ratio
of longfin yellowtail fed the SPC-algal diets were largely comparable to that of fish fed the FM100 diet. Small, but
significant differences in nitrogen retentionwere observed,with fish fed the FM100 diet outperforming those fed
the FM40 and FM 20 diets.
