Abstract

Growth ecology of Pila globosa was studied in the simulated habitat with reference to its natural food habit. Growth rate and obesity index value for the snail population reared on natural aquatic food plants were higher than those, reared on cultivated food, Puni Basela rubra.
For natural food, the minimum and maximum mortality rates at age intervals of 224-238 days and 0-14 days were calculated as 0.00 and 16.00 while, on supplied cultivated vegetable food, B. rubra at 252-266 days and 0-14 days age intervals, were obtained as 0.00 and 18.00 respectively. The life table was constructed on 266 days study of snails, reared on both types of food plants. The findings indicate the possibility of snail culture on large scale, in simulated habitats provided with physico-chemical parameters, like water temperature, pH, turbidity and dissolve oxygen of water, strictly maintained.
