三疣梭子蟹是目前虾池养殖的主要对象。但是传统的养殖方式不能克服梭子蟹同类相残的生产难题，也不能防止梭子蟹残杀同池对虾、蛤类等混养品种，因而造成地养产量、效益较低。1999年我们进行了三疣梭子蟹吊漂养殖300亩，总产量达48吨，亩产160公斤，亩产值艺1200元，亩净收益7 Portunus trituberculatus is currently the main target of breeding. However, the traditional farming methods can not overcome the production problems of the same type of crabs and can not prevent the crabs from killing the same types of polyculture products such as shrimp, clams and the like, thus resulting in low yield and low efficiency. In 1999, we conducted 300 mu of floating and breeding of Portunus trituberculatus, with a total output of 48 tons and a yield of 160 kilograms per mu, an output value of 1200 yuan per mu, a net profit of 7 mu
