河蟹大眼幼体培育至期仔蟹的试验

Experiment on Culturing Crab from Megalopa to Ⅲ Stage Larval

利用网箱、水泥池和池塘分别培育人工半咸水繁殖的河蟹大眼幼体至 期仔蟹 ,以水草为隐蔽物 ,新鲜鱼、虾等肉糜为主要食物 ,保持良好水质 ;采取上述技术措施 ,网箱内培育的仔蟹成活率为 75%、水泥池达 86 %、池塘为 4 0 .5%。

Crab,reproduced in man made brackish water,camouflaged by aquatic weed,fed on meal made of crayfish and fresh fish and maintained in qualified water,are cultured seperataly from megalopa to Ⅲ stage larval in cage,cement pool and pond.The results show that the larval surviral rate are 75%(cage),86%(cement pool) and 40 5% (pond) respectively.
