Growth performance and gonad maturation of amur catfish, silurus asotus in captivity

This study was aimed to determine the growth performance and gonad maturation of Amur catfish, Silurus asotus reared in captivity. A total of 600 juvenile Amur catfish were reared in a 20-tonne aerated fibreglass tank for 3 months. The changes to body weight (mean ± SD) of Amur catfish at day 14 was...
