摘要
为了解饥饿状态下奥尼罗非鱼(体重80～100g)肌肉和全鱼能量物质消耗的变化过程,分别在饥饿1、4、8、16、24、32、40、48d后进行取样,测定肌肉和全鱼的水分、粗脂肪、粗蛋白和灰分含量。结果表明,全鱼、肌肉水分和灰分含量随饥饿时间延长而递增,粗蛋白和粗脂肪含量随饥饿时间延长而递减。在48d的饥饿过程中,肌肉粗蛋白含量由18.82%下降到16.42%,蛋白质消耗率为-12.66,粗脂肪含量由1.79%下降到1.03%,粗脂肪消耗率为-44.62。全鱼粗蛋白含量由17.43%下降到15.85%,蛋白质消耗率为-9.84,粗脂肪含量由2.98%下降到2.11%,粗脂肪消耗率为-31.05。饥饿期间试验鱼的丰满度相对稳定。
The metabolic course of energy substance in the muscle during starvation period was studied.Samples were picked up in the 1st,4th,8th,16th,24th,32nd,40th,48th day during starvation period and the chemical composition (moisture,lipid,protein and ash) in the whole fish and the muscle were detected.The results showed that content of moisture and ash decreased,while the content of lipid and protein increased.During the starvation period,the protein compostion in the muscle decreased from 18.82% to 16.42%.The rate of protein consumption was -12.66.The lipid composion in the muscle decreased from 1.79% to 1.03% while the rate of lipid comsumption was -44.62.At the sametime,the protein compostion in the whole fish decreased from 17.43% to 15.85%.And the rate of protein consumption was -9.84 while the lipid compositon in the whole fish decreased from 2.98% to 2.11%.The rate of lipid consumption was -31.05.
