Comparative Study on Growth, Feed Consumption and Survival of Spiral babylon Babylonia spirata Linnaeus, 1758 (Mollusca: Gastropoda) Fed with Formulated Diets

摘要

A growth trial was conducted to determine the effects of the dietary protein level on growth, feed utilization and survival of Babylonia spirata. Triplicate groups of 50 animals (with an initial average weight of 49.24 +/- 0.8 g) were stocked in 50-1 tanks and fed to apparent satiation twice daily for three months with two experimental diets of 30% and 40% protein content and control diet of fresh meat clam. Growth of snails that were fed with natural food was not significantly (P<0.05) higher than those fed with the experimental diets. There was no significant difference (P>0.05) in growth and Feed Conversion Ratio between snails that were fed with experimental diets. Present study infers that a diet containing 30% and 40% of protein content may be recommended for the growth of B. spirata.
