　　选用初始体重为(2.15±0.10)g中华绒螯蟹(Eriocheir sinensis)雄性幼蟹,随机分为5组(每组12只幼蟹),饲喂100％鱼油组、100％豆油组、100％亚麻油组、50％鱼油-50％豆油组、50％鱼油-50％亚麻油组(各组分别用F1,F2,F3,F4,F5表示)不同脂肪源配制的五种等氮等能饲料.实验蟹单个体养殖,实验周期为112d.结果 表明,F5组体重、壳长、壳宽、增重率和特定生长率都显著高于其它饲料组(P＜0.05),各组的蜕壳间隔和肝胰腺指数没有显著差异(P＞0.05).

不同饵料对拟穴青蟹幼蟹生长性能及体色的影响

拟穴青蟹生产养殖中,其生长性能及存活率备受养殖户关注；市场上,消费者对拟穴青蟹体色也有一定需求,颜色接近野生拟穴青蟹的养殖拟穴青蟹更受欢迎.本实验为此分析了不同饵料对拟穴青蟹幼蟹增重率、存活率以及背甲、大螯颜色的影响,以期为拟穴青蟹人工配合颗粒饲料开发及生产养殖提供基础参考.实验分3组,依次为投喂小杂鱼组(D1组)、投喂淡水螺蛳肉组(D2组)和投喂自制人工配合颗粒饲料组(D3组).实验用拟穴青蟹幼
