摘要
采用四因子三水平的正交实验法,研究了河蟹蚤状幼体至大眼幼体阶段对饲料中蛋白质、脂肪、矿物盐及复合维生素的适宜需求量。结果表明,影响河蟹其成活率的因素主次顺序为:蛋白质>维生素>矿物盐>脂肪,其最优水平分别为:蛋白质55.28%;维生素2%;矿物盐6%;脂肪17.39%。
The appropriate requirements of Chinese mitten crab(Erioecheir sinesis) food from zoea to megalopa for protein,fat,mineral and compound vitamin were studied.Nine experimental diets used albumin and white fish meal as main protein sources,soybean oil and fish oil (1∶3) as fat sources, α-starch as sugar source,and supplemented with different levels of mineral and compound vitamin as the addition of enzyme,binder, and attractive. The cross tests method of four factors and three levels adopted, using survival rate as index.Results showed factors influencing on the survival rate of crab larvae were protein>vitamin>mineral>fat, and the optimum level was protein 55.28%, vitamin 2 %, mineral 6 %,fat 17.39 %.
