Meat and Bone Meal as an Alternative for Fish Meal in Soybean Meal-Based Diets for Florida Pompano, Trachinotus carolinus L.

Alternative protein feedstuffs are potential surrogates for fish meal in the diet of Florida pompano. This study was designed to evaluate the replacement of fish meal with meat and bone meal in a soybean meal-based diet for Florida pompano. In Trial I (10 wk), the basal diet ( FM15, formulated to contain 40% crude protein and 10% lipid) containing 15% fish meal was modified by the isonitrogenous replacement of fish meal with meat and bone meal producing diets with 10 ( FM10), 5 ( FM05), and 0% ( FM0) fish meal. In Trial II (8 wk), the FM0 served as the basal diet (Tau 0) and was modified by the additive supplementation of taurine to produce three test diets containing 0.25 (Tau 0.25), 0.5 (Tau 0.50), and 0.75% (Tau 0.75) taurine. In Trial I, reduced weight gain (220.1%), feed efficiency (0.31), and survival (84.5%) were observed in fish fed the FM0 diet ( P < 0.05). In Trial II, the supplementation of taurine improved the growth performance, survival, and protein and energy retention efficiencies of Florida pompano ( P < 0.05). These results indicate that the supplementation of taurine was required in these feed formulations and that meat and bone meal is a good alternative ingredient for fish meal in soybean meal-based diets for Florida pompano.
