摘要
在早春利用水泥池塑料大棚，采取控温控光，充气、移植水草（喜旱莲子草）、控制水质及合理投饵等强化培育技术，将长江水系中华绒整蟹大眼幼体培育成“早豆蟹”，使蟹苗当年养成商品蟹，改革河蟹两年养成的传统生产模式。经过两年的研究，在1287．2m2试验池中共培育出“早豆蟹”183万只，平均每平方米700多只。成活率达60％，投入产出比为1：2．5，经济效益显著。
The large-eye larvae of Eriocheir sinensis from the Yangtze River system werecultured into mini-crabs in early Spring in cement pools with plastic shed by theculture methods of coNtrolling temperature and Light, filling air, planting water-weeds, keeping water quaLity and putting in feeds, etc. The mini-crabs can becultured into commercial crabs. According to 2 year's researches, l .83 million mini-crabs were cultured in 1267.2 square meters in total, with an average of 70O cradsper m2. The survive rate of mini-crabs reached tO 6O%. It showed huge economicprofits with this culture technique for the ratio Of input to output is 1:25.
