چکیده انگلیسی


• Excessive Cu reduced growth performance of larger yellow croaker.
• Cu could accumulate to the higher concentration in whole-body, muscle and liver of fish.
• High Cu intake inhibited activities of antioxidant enzyme and lipid synthetase.

A study was carried out to test the responses of juvenile larger yellow croaker Larimichthys croceus to high Cu intake. Experimental diets were formulated containing three levels of Cu: low Cu (3.67 mg/kg), middle Cu (13.65 mg/kg) and high Cu (25.78 mg/kg), and each diet were fed to large yellow croaker in triplicate for 10 weeks. Final body weight, weight gain and feed intake were the lowest in high Cu group, but hepatosomatic index was the highest; Cu concentrations in the whole-body, muscle and liver of fish fed low Cu diet was the lowest; Liver superoxide dismutase, catalase and glutathione peroxidase activities in fish fed high Cu diet were lower than those in fish fed other diets; The higher content of liver thiobarbituric acid reactive substance content was found in high Cu group, followed by middle Cu group, and the lowest in low Cu group; Liver 6-phosphogluconate dehydrogenase, glucose-6-phosphate dehydrogenase, malic enzyme, isocitrate dehydrogenase and fatty acid synthase activities were the lowest in high Cu group, but lipoprotein lipase activity was the highest. This study indicated that high copper intake reduced growth of juvenile larger yellow croaker, inhibited activities of antioxidant enzymes and lipid synthetases, and led to energy mobilization.
