摘　　要：选择草鱼主养池塘为研究池塘,分析架设生物浮床的池塘中草鱼(Ctenopharyngodon idellus)和团头鲂(Megalobrama amblycephala)的生长和肌肉品质特性。池塘养殖试验时间为180d,试验期间测定草鱼和团头鲂生长指标,并利用生化分析和物性分析方法测定肌肉营养成分、系水力和质构特性。试验结果表明:试验池塘的草鱼和团头鲂的终末体质量高于对照池塘的养殖鱼类;试验池塘2种鱼的肥满度都显著高于对照池塘;试验池塘和对照池塘空壳体质量比没有显著差异。试验池塘草鱼和团头鲂的肌肉滴水损失和失水率均显著低于对照池塘,而熟肉率显著高于对照池塘。试验池塘的鱼类肌肉粗蛋白显著高于对照池塘;粗脂肪含量都高于对照池塘,在草鱼中差异显著,团头鲂差异不显著;试验池塘草鱼水分显著低于对照池塘,团头鲂水分和2种鱼灰分都没有显著差异。肌肉的质构特性分析表明,试验池塘草鱼的硬度、胶黏性、咀嚼性显著高于对照池塘;试验池塘草鱼回复性和凝聚性显著低于对照池塘,试验池塘团头鲂肌肉弹性显著高于对照池塘。In this study,we investigated the effect of bio-floating bed on growth and muscle quality of grass carp （Ctenopharyngodon idellus） and blunt snout bream（Megalobrama amblycephala） in ponds.Two modes of culture ponds were chosen：one equipped with bio-floating bed was the experimen- tal pond, and the other without beds was the control pond. At the end of the experiment, we measured the growth parameters, the muscle conventional nutrients, water holding capacity （WHC）, and texture char- acteristics using biochemical and physical methods.The results showed that the final weight of fish cul- tured in the experimental pond was higher than that in the control pond. The hepatic somatic index of grass carp （1.77%） in the experimental pond was significantly lower than that of the control （2.47%）. The condition factors of grass carp and blunt snout bream （1.73 and 2.56, respectively） were significant- ly higher than those of the control （1.64 and 2.40, respectively）. There was no significant difference in the eviscerated weight of both carp and bream between the experimental （91.06 and 88.28,respectively） and the control （89.22 and 88.49, respectively） ponds. The drop loss （14.49 % and 10.69, respectively） and water loss rate （17.52% and 10.34%,respectively） of the experimental grass carp and blunt snout bream were significantly lower than those of the control. The cooked rate of the experimental fish was significantly higher than the control. The muscle crude fat content （1.89%） and crude protein content （14.60%） of grass carp in the experimental ponds were significantly higher than those of the control （ 1.54 % and 13.46 %）, whereas muscle water content （81.68 % ） of the experimental fish was significantly lower than that （82.65 %） of the control.There is no significant difference in muscle ash content between the two groups. Unlike grass carp, only muscle crude protein content （17.23%） of the experimental bream was significantly higher than that （15.9
