为了探索低盐度地区南美白对虾无公害池塘养殖技术,2004年,博兴县水产局进行了低盐度池塘无公害养殖南美白对虾试验。试验池塘106.7 hm2(1 600亩),投放虾苗9 625万尾,5月15日开始投苗,至9月底收获, 生长期135天,成虾平均规格11.8 cm,共收获成虾32.5 万kg,共获收益498万元,投入产出比1:2.2,获得了低盐度池塘无公害养殖南美白对虾的成功。现将试验的主要技术措施报告如下:
In order to explore the pollution-free pond culture technology of Penaeus vannamei in low-salinity area, in 2004, Boxing County Fishery Bureau conducted the experiment of pollution-free culture of P. vannamei in low salinity ponds. The test ponds were 106.7 hm2 (1 600 mu) with 9.25 million shrimp feedings. Seedlings were planted on May 15 and harvested at the end of September. The growing period was 135 days. The average shrimp size was 11.8 cm, and a total of 325 000 kg shrimp , A total profit of 4.98 million yuan, input-output ratio of 1: 2.2, access to low-salinity pond pollution-free culture of P. vannamei success. Now test the main technical measures are reported as follows:
