中国龙虾人工养殖饵料的初步研究

Studies on the rearing effects of various diets for the spiny lobster, Panulirus stimpsoni

本文研究了贻贝、牡蛎、杂虾、杂蟹、杂鱼和配合饲料 6种饵料对中国龙虾的饲养效果。结果表明 :饵料对中国龙虾的蜕壳率、蜕壳后体重增长率、生长率和饵料转换效率都有显著的影响 ,而对中国龙虾蜕壳后体长增长率和存活率影响并不明显。各种试验饵料中翡翠贻贝是饲养中国龙虾的最好饵料 ,其次是牡蛎、杂虾、杂蟹 ,杂鱼只能作为辅助性饵料 ,配合饲料的某些成分及其适口性。

Six diets: mussel, oyster, trash shrimp, trash crab, trash fish and formula diet were fed the spiny lobster, Panulirus stimpsoni, for 104 days. And the effects of various diets on growth (molt increment, intermolt period) and survival for rearing the spiny lobster, Panulirus stimpsoni were determined. The results showed there were difference in growth rates, molt body weight growth rates, intermolt periods and food coefficients significantly along the various diets, and no significant difference in the molt body length growth rates and survival rates. The mussel was the best food for the culture of the spiny lobster, follows were the trash shrimp, trash crab and the oyster. The trash fish had to be fed for the spiny lobster in combination with some other kinds of diets. To improve the rearing effect is requirement for the artificial formula diet to add some components and feeding activators.
