近年来,由于海洋渔业资源结构的变化,三疣梭子蟹海捕资源急剧衰退,商品价值倍增,人工养殖迅速兴起。目前,三疣梭子蟹的苗源绝大部分依靠自然海区捕捞苗种,个体大小差异很大,相互残食现象十分明显,相应地加大了养殖难度。为了促进三疣梭子蟹养殖产业化发展,从2002年开始,我们在 In recent years, due to the changes in the structure of marine fishery resources, sea crab fishing Port Catfish crabs sharp decline in resources, double the value of commodities, the rapid rise of artificial breeding. At present, most of the seedlings of Portunus trituberculatus rely on the fishing of natural seafloor. The size of individual is quite different, and the phenomenon of mutual residual feeding is very obvious, which increases the difficulty of breeding accordingly. In order to promote the portunus crab breeding industrialization, since 2002, we are here
