Epidemiology of emerging diseases and disorders in cage cultured Pangasius spp. in Pahang, Malaysia

Pangasius hypophthalmus or famously known by local Malaysians as Patin Hitam is one of the most important sources of food in Malaysia. It is widely cultured in the Peninsular Malaysia especially in Pahang as Patin is a popularly consumed freshwater fish. Global economic interest in the fish has incr...
