摘 要: | 研究了大黄鱼与三疣梭子蟹的池塘混养技术。2011年4月初向池塘内投放80~100 g/尾的大黄鱼,混养池塘投放4 000~5 000尾/hm~2,共投放4 500尾/hm~2,5月下旬投放规格为150~200只/kg的三疣梭子蟹,混养池塘投放30 000只/hm~2,共投放33 000只/hm~2,梭子蟹单养池塘60 000只/hm~2,共投放66 000只/hm~2。大黄鱼单养池塘投放8 000~10 000尾/hm~2,共投放9 000尾/hm~2;当年11月中下旬收获商品大黄鱼,大黄鱼单养池塘平均单产2 118.7~2 238.7 kg/hm~2,混养池塘1 329.6~1 460.3 kg/hm~2,存活率分别为76.2%和85.3%;9~11月收获商品梭子蟹,梭子蟹单养池塘的平均单产1 701.8~1 747.1 kg/hm~2,混养池塘的平均单产为1 253.5~1 314.3kg/hm~2,存活率分别为17.8%和21.3%。混养、大黄鱼单养、梭子蟹单养投入产出比分别为1∶1.83~1∶1.96、1∶1.69~1∶1.81、1∶1.57~1∶1.76。由此可见,大黄鱼与三疣梭子蟹的混养有助于提高综合效益。

Abstract: | The pond mixed culture between P.crocea and P.trituberculatus was studied in this paper.In early April of 2011,80-100 g/ind.of P.crocea was put in the pond, and there were 4 000-5 000 ind./hm2 of P.crocea in polycultive pond, a total of 4 500 ind./hm2 .In last dekad of May, 150-200 ind./kg of P.trituberculatus was put in the pond, and there were 30 000 ind./hm2 of P.trituberculatus in polycultive pond, a total of 33 000 ind./hm2 .There were 60 000 ind./hm2 of P.trituberculatus in monocultive pond, a total of 66 000 ind./hm2 , while there were 8 000-10 000 ind./hm2 of P.crocea in monocultive pond, a total of 9 000 ind./hm2 .In late November of the same year, the adult fish was har-vested, the monocultive production reached 2 118.7-2 238.7 kg/hm2 and the polycultive production was 1 329.6-1 460.3 kg/hm2 for adult P. crocea.Their survival rates were 76.2% and 85.3% respectively.From September to November, the adult crab was harvested, the monocultive production reached 1 701.8-1 747.1 kg/hm2 and the polycultive production was 1 253.5-1 314.3 kg/hm2 for adult P.trituberculatus.Their survival rates were 17.8% and 21.3%respectively.The input-output ratios were 1∶1.83-1∶1.96 of polyculture, 1∶1.69-1∶1.81 of P.cro-cea monoculture and 1∶1.57-1∶1.76 of P.trituberculatus monoculture.It was clear that polyculture of P.crocea and P.trituberculatus was con-ducive to improving integrated benefit. |
