A study on trematode obtained from freshwater snails in 30 grow-out giant gourami ponds supplied by well water was conducted Chau Thanh district, Tien Giang province, Vietnam.

Eight snail species belonging to 8 genera, 4 families found including Sermyla tornatella (48.6%), Sinotaia lithophaga (19.3%), Filopaludina sumatrensis (15.4%), Melanoides tuberculata (6.4%), Pomacea sp. (4.7%), Bithynia siamensis (4.2%), Thiara scabra (0.8%) Tarebia granifera (0.6%). Cercariae recovered only two of with Xiphidio cercariae Furcocercous a prevalence 7.4%, Pleurolophocercous infection rate 6.9%. trematodes (26.7%), 7 (23.3%), 3 (10.0%) season, respectively (P>0.05). More research epidemiology fishponds should be done contribute food safety sustainable aquaculture.
