Zinc (Zn) is an essential micromineral for fishes and is closely related to many biochemical processes. This study was designed to determine the effects of dietary Zn supplied in practical diets on the pond-raised hybrid snakehead (Channa maculate ♀ × C. argus ♂). Five extruded diets were supplemented with different Zn sulfate levels (analysed Zn values: 42.33, 65.79, 82.27, 100.41, and 120.18 mg kg-1). A total of 900 fish (initial weight 3.33 g) were divided into three net cages per treatment and fed twice daily to apparent satiety. The results indicated that dietary Zn influenced growth parameters, antioxidant capacity and innate immunity. The moisture and crude lipid contents of the whole body were significantly affected by dietary Zn concentration (P 0.05). However, copper (Cu) content in the whole body, vertebrae, and liver increased and then decreased as dietary Zn increased (P |
