Effects of different diets on the survival rate and growth performance of mystery snail (Cipangopaludina chinensis) in culture tank

Abstract

This study was conducted to evaluate the effects of different diets on the survival and growth performance of snails. The experiment was conducted with 3 treatments and each with 3 replicates: 1) 100% tilapia pellets (N1F); 2) 50% fish pellets and 50% shrimp pellets (N2FS); 3) 100% Whiteleg shrimp pellets (N3S). Adult snails with initial weight and height of 7.89g and 32.35mm, respectively were placed in a plastic tank with a volume of 250 L (80 cm × 60 cm) and stocked at a density of 24 individuals/tank . The results showed that after 90 days of rearing, the relative weight growth of snails in the FS treatment (0.26±0.01 %/day) was the highest compared with the S treatment (0.23±0.20 %/day) and treatment F (0.24±0.01 %/day.The survival rate was highest in treatment FS (66.66%) and lowest in treatment F (59.72%). The research results showed that the diets of 50% fish balls and 50% shrimp pellets are suitable for raising C. chinensis snails.
