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

A growth trial was conducted to determine the effects of the dietary protein level on growth, feed utilization and survival of Babylonia spirata. The triplicate groups of 50 animals (with an initial average weight of 49.24 +0.8 g) were stocked in 50-l 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. The growth of snails that were fed with natural food was not significantly (P0.05) in growth and FCR between snails that were fed with experimental diets. The result of the present study indicates that a diet containing 30% and 40% of protein content may be recommended for the growth of B. spirata.
