Pangasius hypophthalmus (Sauvage, 1878) is an omnivorous fresh water fish originating from the Mekong River in Vietnam (Rodríguez et al., 2018). Panga has several names as sutchi catfish, striped catfish, iridescent shark-catfish, or tra fish, it has high acceptability by consumers due to its low price, good taste and white meat that can replace cod or other expensive white fishes (Little et al., 2012 ; Guimarães et al., 2016). Recently, Pangasius become one of the best aquaculture candidates in several countries as it can be cultured easily in ponds, concrete tanks or fish cages, it has the ability to survive at high stocking density, poor water quality, low oxygen levels and can easily accept external feeding. Moreover, it considered as a fast growing fish with high yield production and disease resistant that meet up the farmer"s demand. (Hill and Hill, 1994; Ali and Haque, 2011; Vaishnav et al., 2017).
