海水池塘半滑舌鳎-日本对虾-菊黄东方鲀混养试验

Trial for polyculture of Cynoglossus semilaevis with Penaeus japonicus and Takifugu flavidus in seawater pond

为全面推广半滑舌鳎养殖技术,提高海水池塘养殖效益,进行了不同规格半滑舌鳎(Cynoglossus semilaevis)与日本对虾(Penaeus japonicus)和菊黄东方鲀(Takifugu flavidus)的池塘混养对比试验,其中半滑舌鳎放养密度2250尾/hm^(2),放养规格分别为150~250、5~10、20~50 g/尾,日本对虾放养密度6万尾/hm^(2),菊黄东方鲀放养密度6000尾/hm^(2),规格0.54~0.56 g/尾。结果显示,放养规格不小于150 g/尾的半滑舌鳎高雌苗种,当年可收获规格500 g/尾以上的商品鱼,实现综合产量2801.0 kg/hm^(2),综合效益99404元/hm^(2)。

To promote the technique for farming the tongue sole(Cynoglossus semilaevis),and improve economic efficiency in seawater pond farming,polyculture of tongue sole of different stocking size with the kuruma prawn Penaeus japonicus and tawny puffer Takifugu flavidus in pond were compared.The stocking density of the tongue sole was 2250 ind./hm^(2)with the size of 150~250、5~10、20~50 g/ind.,respectively.The stocking density of the kuruma prawn was 60000 ind./hm^(2),and that of tawny puffer was 6000 ind./hm^(2)with the size of 0.54~0.56 g/ind..The result showed that the harvest size of the tongue sole could reach 500 g/ind.with total output 2801.0 kg/hm^(2)and economic efficiency 99404 yuan/hm^(2)if the stocking size exceeds 150 g/ind.
