研究了网围无公害培育一龄蟹种和成蟹养殖技术,检测了试验区水质、底泥和成蟹品质。结果表明,网围河蟹养殖达到无公害标准。投草型、种草型和轮牧型养殖方式分别适合15亩左右、50亩左右和100亩以上规模的网围养殖,平均亩产达41.34～52.09kg,平均亩效益为1780.77～1988.89元。无公害养殖技术提高了河蟹品质,对维护浅水草型湖泊生态环境,促进经济循环和河蟹产业健康发展具有积极意义。

This paper studied the breeding of one-age-old crab species and crab breeding without pollution on the nets. The water quality, sediment and crab quality of the test area were tested. The results show that net Wai crab farming reached the standard of pollution-free. Grass, grass and round grazing methods are suitable for about 15 acres, about 50 acres and more than 100 acres of net fence farming, the average yield of 41.34 ~ 52.09kg, the average yield per acre 1780.77 ~ 1988.89 yuan. Pollution-free culture technology improves the quality of crabs and has positive significance for maintaining the ecological environment of shallow grass-lakes and promoting the economic cycle and the healthy development of crab industry.
