Abstract

A feeding trial was undertaken to develop a low fishmeal practical diet for mangrove red snapper (Lutjanus argentimaculatus) by replacing 60% fishmeal (FM) protein with either soybean meal (SM) or peanut meal (PM) and 10% fish solubles (FS) or krill solubles (KS) supplementation. Seven isonitrogenous (crude protein: 40% dry matter) and isolipidic (crude lipid: 9% dry matter) diets were prepared [Diet 1 / FM100, Diet 2 / (FM40+SM), Diet 3 / (FM40+SM+FS), Diet 4 / (FM40+SM+ KS), Diet 5 / (FM40+PM), Diet 6 / (FM40+PM+FS), Diet 7 / (FM40+PM+ KS)]. Triplicate groups of fish (initial body weigh: 1.46±0.02 g, mean ± S.D.) were stocked in 150-l circular fiberglass tanks at a density of 18 fish per tank. Fish were hand fed the respective experiment diets to satiation twice a day for 56 days. Results showed that there were no significant (p>0.05) differences in values of final body weight (FBW) or weight gain (WG) among the fish fed with the FM100 diet and those fed with (FM40+SM), (FM40+SM+FS) and (FM40+SM+ KS) diets. For fish fed with the (FM40+PM) diet, WG were significantly lower when compared to fish fed with the other experiment diets.
