摘要
半滑舌鳎肉质鲜美、营养丰富,具有较高的养殖空间及良好的经济效益,但其自然越冬成活率低的问题已严重制约了半滑舌鳎养殖产业的可持续发展。为此,在江苏连云港市开展了半滑舌鳎室外池塘自然越冬养殖试验,并进行半滑舌鳎混养试验。结果显示:通过池塘改造能够使半滑舌鳎顺利越冬,成活率高达71.7%,收获达到上市规格的半滑舌鳎(0.4 kg/尾左右)760.1 kg;此外通过混养中国对虾、三疣梭子蟹、美洲帘蛤经济品种,使得塘口整体利润达到93286.36元/hm^(2),产出投入比为1.67,池塘养殖效益处于全国前列。该研究解决了半滑舌鳎在江苏池塘中自然越冬成活率低的难题,最大化提高了池塘的经济效益,为半滑舌鳎在江苏地区池塘养殖的推广提供了技术参考。
Cynoglossus semilaevis meat is delicious and nutritious,with high economic value and good economic benefits.But the problem that C.semilaevis can’t overwinter naturally has seriously restricted the development of its breeding industry.Therefore,in this study,C.semilaevis outdoor pond natural overwintering culture experiment and C.semilaevis co-culture experiment were carried out in Lianyungang City,Jiangsu Province.The results showed that C.semilaevis could overwinter successfully through pond reconstruction,the survival rate was as high as 71.7%,and 760.1 kg C.semilaevis(about 0.4 kg/pcs)was harvested to meet the market specifications.In addition,through the co-culture of Penaeus chinensis,Portunus trituberculatus,Mercenaria mercenaria,the overall profit of the pond reached 93286.36 yuan/hm^(2),the output-input ratio was 1.67,and the benefit of pond aquaculture was in the forefront of China.This study solved the problem of low natural overwintering survival rate of C.semilaevis in ponds of Jiangsu Province,maximized the economic benefits of ponds,and provided techniques for the promotion of C.semilaevis in ponds of Jiangsu Province.
