利用小型水库的 10 6 .6 7hm2 进行了中华绒螯蟹的增养殖试验 ,放养 70万只 ,密度约为6 5 0 0只 /hm2 。在整个养殖过程中 ,中华绒螯蟹的生长完全依靠天然饵料。当年收获的蟹规格为 15 0g/只 ,回捕率在 12 %左右 ,实现产值近 10 0万元。
Eriocheir sinensis was cultured by using 10 6. 7hm 2 of small reservoirs with stocking of 700,000 and a density of about 6500 / hm2. Throughout the breeding process, the growth of Eriocheir sinensis depends entirely on natural feed. The crabs that were harvested in the year were 15 0 g / bird and the recovery rate was about 12%, with a production value of nearly 10 million.
