[Abstract]:The effects of different storage methods on fish meal quality were studied, and the culture effects of Penaeus vannamei and Grouper obliquus were evaluated. The results were as follows: 1. The effects of different storage methods (temperature, antioxidant dosage and storage time) on the quality of fish meal were studied. The changes of volatile base nitrogen, histamine, acid value and thiobarbituric acid value of fish meal were studied under the condition of 0,300,800 mg/kg of antioxidant (ethoxyquinoline) and room temperature, respectively. The acid value and thiobarbituric acid value of 4oC stored fish meal were lower than those of room temperature stored fish meal at the same storage time. Histamine increased first and then decreased with the storage time prolonging. Adding antioxidants was beneficial to the quality of fish meal. The growth and physiological effects of Penaeus vannamei were studied in a two-factor experimental design. The storage time of fish meal was 45 days, 90 days and 135 days, the antioxidant level was 0,300,800 mg/kg, and the fresh fish meal was stored at 4oC and room temperature, respectively, as the control group. 19 kinds of feeds were prepared and fed to the juvenile Penaeus vannamei shrimp with the initial weight of (0.40+0.02) g for 8 W. 2 280 healthy and uniform shrimps were randomly divided into 19 experimental groups with 3 replicates in each group and 40 shrimps in each replicate. The specific growth rate and protein efficiency were the highest in group A, and the feed coefficient was the lowest in group B. The feed coefficient and protein efficiency were the lowest in group B at 135 D and the highest in group B at 800 mg/kg. Fish meal storage time, antioxidant levels had significant effects on total antioxidant capacity and activities of superoxide dismutase, catalase and glutathione peroxidase (P 0.05). Fish meal storage time, antioxidant levels and interaction between them had significant effects on liver and pancreas of Penaeus vannamei. Trypsin activity and TRS mRNA expression in glands were significantly affected (P 0.05). Under the condition of this experiment, the high antioxidant level of fish meal stored at 4oC for a short time was not conducive to the growth of Penaeus vannamei. Storage time at room temperature was the primary factor affecting the culture effect of Penaeus vannamei. Penaeus nabinensis can resist the damage of fish meal with poor freshness by improving its antioxidant capacity. 3. The effects of different storage methods of fish meal on the growth and physiological effects of grouper were studied. Under warm conditions, 19 kinds of diets were prepared with fresh fish meal as the control group and fed 8 W juvenile grouper with the initial weight of 18.75 (+0.05) G. There was no significant effect on survival rate, feed coefficient and protein efficiency (P 0.05). Storage time at room temperature had significant effect on weight gain and specific growth rate (P 0.05). The weight gain rate and specific growth rate of 45 D storage group were significantly higher than those of 135 D storage group (P 0.05). Fish meal storage time, antioxidant levels and their interaction had significant effects on total antioxidant capacity and superoxide dismutase, catalase and glutathione peroxidase activities in the liver (P 0.05). Fish meal storage time, antioxidant levels and both had significant effects (P 0.05). Interaction between the two groups had significant effects on the activity of trypsin and the expression of TRS mRNA in the liver of grouper (P 0.05). The harm of fish meal.
