Life cycle and fecundity of freshwater snail (Viviparus bengalensis) were studied for a period of three months in nine integrated multi-trophic aquaculture (IMTA) ponds. Average size and depth of the ponds were 40 m2 and 1 m, respectively. The experiment consisted of three treatments in triplicate. Snail was sampled at 7-day intervals using Ekman Dredge. An adult snail carried approximately 30-40 juveniles. Fecundity of a snail was found 37±2.0 and 39±1.0 in T2 and T3, respectively, and life cycle completed within 40-42 days. The physico-chemical parameters were found more or less similar in the treatments and were within the suitable ranges for snail culture. The findings of the experiment indicate that IMTA pond is a suitable habitat for snail culture.
