Abstract

An experiment was conducted to determine the effect of complete replacement of fishmeal using cottonseed meal fortified with lysine and methionine in the diet of snubnose pompano, Trachinotus blochii on growth, body indices and biochemical composition. A total of 180 Juveniles of snubnose pompano with the average weight of 12.5+ 0.5 g were distributed in five treatments each with triplicates. Five isonitrogenous and isolipidic experimental feeds were formulated with 0, 8.7, 17.4, 26.0 and 34.7% of cottonseed meal to replace fishmeal protein (0, 25, 50, 75, and 100%) and fed to respective treatments (0CSM, 25CSM, 50CSM, 75CSM and 100CSM). There was significant difference (P<0.05) in daily growth co-efficient (DGC), thermal growth co-efficient (TGC), biomass gain (BG) and geometric mean body weight (WG) among the treatments. Feed intake (FI), feed gain ratio (FGR), protein retention efficiency (PRE) and energy retention efficiency (ERE) of fish from different treatments showed significant difference (P<0.05) and better responses were noticed in 0CSM group followed by 100CSM group. Higher viscera-somatic index was recorded in 50CSM group and gastro-somatic index was observed in 0CSM group. Better condition factor and hepatosomatic index were observed in 100, 75 and 0CSM. The relative feed cost of 100CSM diet was 10.08% lower than 0CSM diet. Better relative feed cost savings of 10.79% was witnessed in 100CSM. Fishmeal can be completely replaced using cottonseed meal with lysine and methionine supplementation in the diet of snubnose pompano without adverse effect on growth, body indices and biochemical composition with adequate savings of production cost.
