应用生物饲料饲养克氏原鳌虾并和普通饲料进行营养评价及养殖效果比较，通过对克氏原螯虾的生长速度和性腺发育指标的测定和观察，研究和评价生物饲料对克氏原螯虾的养殖效果。试验结果表明，生物饲料和普通饲料相比其氨基酸数量、种类更为齐全，尤其是必需氨基酸含量更为丰富、比例更为平衡，即两者的必需氨基酸指数EAAI有显著性差异（ P＜0．01）。生物饲料组和普通饲料组经2个月的比较饲喂养殖，平均生长速度（日均增重率）分别为1．75％，1．48％；性腺成熟系数、肝体比和相对怀卵量等指标经数理统计检验显示，在2种饲料之间均存在不同程度的差异性（P＜0．05），即生物饲料对克氏原螯虾的生长和性腺成熟发育和普通饲料相比具有显著性差异，表明生物饲料对克氏原螯等水产养殖有着较好的饲养效果，具有良好的推广价值。

Compare the effect of feeding biology feed and general feed to breed crayfish , to value the biology feed effect by observing and mensurating the crayfish ’ s growth rate and the gonad growth .The results show that the biology feed are excelled than the general feed on the amino acids kinds and the content of the EAA especially , namely the otherness on EAAI is prominent .The average growth rate of the biology feed and general feed are 1.75%and 1 .48%after two months feeding .There are some different degree otherness on the gonad growth coeffi-cients,the ratio of the livert to body and the comparative eggs quantity ,after math statistic checkout ,the otherness on body growth and gonad growth between biology feed and general feed to feed caryfish is prominent ,the study in-dicate that the biology feed have good value to crayfish and aquiculture .
