    Abstract


    To determine the infection of fishborne zoonotic trematodes (FZT), metacercariae stage, in juveniles and grow-out Sutchi catfish in Tiengiang province,aresearch was conducded from April 2017 to April 2018 with a total of 272 grow-out fish (at 48 ponds) and 3320 fingerling fish (at 64 ponds). Fishsampleswere tested with the parasite method and metacercariae genus were identified by morphology method. It was found that fish were infected with Haplorchis pumilio metacercariae and the prevalences in the fish were higher during the rainy season compared to the dry season (the prevalence of fingerling pond was from 12.5 to 37.5% andgrow-out fish was from 12.1 to 30.0%for the rainy season; the respective figure were from 0.0 to 13.3% and from 0.0 to 25.0%for the dry season). Drying the pond bottom (<2 days), home made food, a snail's presence in ponds and dog/catpresence ) in the farming area were found to be the risk factors of FZT in the fish (P <0.05). Therefore, technical controls should be done to prevent and decrease the FZT prevalence in figerling and grow - out Pangasianodon catfish to contribute to the food safety and human health.
