| Abstract |
A 120-day feeding trial was designed to determine the effects of different dietary protein and lipid levels and protein to energy ratio (P:E) on growth performance and feed utilization of hatchery-reared juvenile spotted babylon, Babylonia areolata, cultured under a flow-through seawater system. Six diets were formulated to contain three protein levels (18, 28, and 36%) and two lipid levels (10 and 15%) in a 3 × 2 factorial design with three replicates to provide six different dietary P:E ratios (50.17, 49.09, 68.50, 65.85, 88.66, and 85.36 mg protein/kcal). Each replicate was stocked with 50 snails (0.12 + 0.01 g, initial weight) and fed to satiation once daily. The results showed that survival was above 96% at the end of the feeding trial in all groups and was not affected by either dietary protein level or dietary lipid level. The highest significant (P < 0.05) growth and feed utilization were observed for juveniles fed diet with a P:E ratio of 88.66 kcal g−1 diet. With respect to dietary protein and lipid levels, the highest (P < 0.05) values for growth and feed efficiency were observed for snails fed a diet containing 36% protein level and the same trend was observed for snails fed a diet with 10% lipid level. This results indicated that the diet containing 36% protein and 10% lipid level with a dietary P:E ratio of 88.66 mg protein/kcal would be suitable for optimum growth and feed utilization of B. areolata juveniles. |
