dc.description.abstractStriped catfish farming in the Mekong Delta have developed strongly. In recent years, the disease situation of striped catfish have increased sharply and it’s affecting the farming process negatively. Therefore, the aim of this study is to map diseases in two locations: An Giang and Can Tho, to provide the essential data for striped cafish farmers to help them in diseases management in the local areas. In the total of 65 ponds sampled (21 ponds in An Giang, 44 ponds in Can Tho), the highest incidence in both locations was bacillary necrosis disease with 43.1% and hemorrhagic disease at 36.9%. . In An Giang, the result recorded that the presence of bacillary necrosis disease and hemorhagic disease accounted for the majority, with the incidence of bacillary necrosis disease concentrated mainly in Chau Phu with 33.3% and Long Xuyen with 42.8%. For hemorrhagic disease, it occurred dispersively in Chau Thanh and Cho Moi with 14.2% and 4.7%, respectively. In Can Tho the presence of all 3 kinds of diseases. In which, the bacillary necrosis diease occurred mainly in Vinh Thanh and Co Do with 11.3% and 9.1%, respectively. The incedence of hemorrhagic diesease in Can Tho higher than An Giang and it concentrated in Vinh Thanh was 22.7% and Thot Not 13.6%. Particularly, the whitist gill and liver concentrated mainly in Binh Thuy with 15.9%. Fish samples were observed for clinical signs to dectect the bacteria by using the streak plate method and PCR technique. PCR results showed possitive results with E.ictaluri and A.hydrophilla. Moreover, this study detected 4 groups of parasites such as: Dactylogyrus sp.; Myxobolus sp.; Trichodina sp. and Epistilis sp.vi_VN
