河蟹仔蟹管道式饲养初步研究

Preliminary Study on Pipeline Culture of Juvenile Crab, Eriocheir sinensis

采用封闭式的蜂窝状塑料管道作为蟹穴，对河蟹仔蟹进行两个月的饲养观察试验，每隔１５ｄ测定一次壳长、壳宽和体重，用数理统计方法分析了河蟹的个体生长特点，比较了蟹穴饲养和非蟹穴饲养以及不同形式的蟹穴饲养效果。结果表明，仔蟹的个体生长为跳跃式的非连续增长。蟹穴饲养对河蟹的壳长、壳宽和体重的生长无不利影响，而增重率明显优于散养。

Using closed honeycomb like pipeline as crab cave, an experiment on rearing of juvenile crab was carried out for two months. The carapace length, width and body weight of crab were periodically measured, and individual growth feature was aualysed by statistical methods. The results show that the individul growth of carb is jumping, not linear. The pipeline culture of crab is feasiable and the growth offeat of L typed crab cave is better than that of I typed one.
