摘　　要：为了研究天然水体长成鳙鱼在不同月份暂养过程中鳙鱼体形、肌肉营养、滋味、免疫及抗氧化物质的变化,采集花亭湖5月、8月、11月和次年3月暂养鳙鱼进行系统研究。结果显示,从体形来看,暂养处理对鳙鱼有瘦身效果;不同月份鳙鱼肌肉基本营养成分含量有差别,暂养处理后,鳙鱼肌肉蛋白质和脂肪含量降低,水分和灰分含量升高;脂肪酸组成发生变化,主要表现在饱和脂肪酸(SFA)含量降低,多不饱和脂肪酸(PUFA)含量升高;肌肉免疫和抗氧化成分含量随着暂养时间的延长显著降低;游离氨基酸总量随着暂养时间的延长不断提高,呈现甜味氨基酸占比不断提高;呈味核苷酸总量提高。In order to study the changes in body shape,muscle nutrition,taste,immunity,and antioxidant substances of adult bighead carp in natural water bodies during temporary rearing in different months,a systematic study was conducted on the temporary cultivation of bighead carp in Huating Lake in May,August,November and March of the following year.The results showed that from the perspective of body shape,temporary feeding treatment had a slimming effect on bighead carp;The basic nutritional content of bighead carp muscle varies in different months.After temporary cultivation,the protein and fat content of bighead carp muscle decreases,while the water and ash content increases;The composition of fatty acids changes,mainly manifested in a decrease in saturated fatty acid(SFA)content and an increase in polyunsaturated fatty acid(PUFA)content;The content of muscle immunity and antioxidant components significantly decreases with the prolongation of temporary maintenance time;The total amount of free amino acids continues to increase with the extension of temporary incubation time,and the proportion of sweet amino acids continues to increase;The total amount of flavor nucleotides increased.
