An 11-week feeding trial was conducted to assess the dietary lysine requirement for juvenile Hemibagrus wyckioides. Six isoproteic and isoenergetic diets (41.66% crude protein, 20.56 kJ/g gross energy) containing 1.1%, 1.5%, 1.9%, 2.3%, 2.7%, 3.1% were prepared feed juveniles (average initial body weights of 1.25 g), respectively. The weight gain, specific growth rate (SGR), conversion ratio (F...
