THE COMPOSITION OF SNAIL SPECIES IN BA TY AND BA LAO CANALS IN BINH CHANH DISTRICT, HO CHI MINH CITY, VIETNAM
Main Article Content
Abstract
A study on the snail composition in Ba Ty and Ba Lao canals in Binh Chanh district, Ho Chi Minh City, was conducted in March and May 2022. A total of 486 samples of snails including 10 species, 10 genera, and 5 families was collected and identified by the morphological method. It includes Tarebia granifera (25.9%), Melanoides tuberculata (25.5%), Sermyla tornatella (18.5%), Pomacea canaliculata (12.6%), Filopaludina sumatrensis (4.3%), Pila polita (4.3%), Bithynia siamensis (4.3%), Thiara scabra (3.5%), Sinotaia lithophaga (0.6%), and Lymnaea viridis (0.4%). The total number of snail species in the rainy season (10 species) was higher than in the dry season (8 species). All sampled snails were cercariae free. The findings provided information about the diversity of snails in canals in Ho Chi Minh City. More research on the harm of snails to rice should be done to contribute to sustainable agriculture development.
