红鳍东方鲀、硬壳蛤与中国对虾池塘混养时生长效果及养殖效益分析

Analysis of growth effect and culture benefit of polyculture of Takifugurubripes, Mercenaria mercenarias and Fenneropenaeus chinensis in pond

不同的水产养殖品种混合养殖可以充分利用海水池塘内的物质资源、改善养殖水质、提高养殖效益,促进养殖水域环境健康可持续发展。本文以红鳍东方鲀(Takifugu rubripes)、硬壳蛤(Mercenaria mercenaria)和中国对虾(Fenneropenaeus chinensis)为研究对象,研究分析了红鳍东方鲀与中国对虾、硬壳蛤与中国对虾、红鳍东方鲀和硬壳蛤与中国对虾三种养殖模式下红鳍东方鲀与硬壳蛤的生长效果,并分别计算了其养殖效益。三种养殖模式下中国对虾的放养量是固定的,均为初始规格20 000尾/kg,放养密度6 kg/hm^(2)。同时,该试验也分别选出了三种养殖模式下养殖效益最高时红鳍东方鲀与硬壳蛤的放养密度。

Polyculture of different aquaculture species can make full use of material resources in seawater ponds,improve aquaculture water quality,increase aquaculture benefits,and promote the healthy and sustainable development of aquaculture waters.Takifugu rubripes,Mercenaria mercenarias and Fenneropenaeus chinensis were studied under the following three culture modes,including:T.rubripes with F.chinensis,M.mercenarias with F.chinensis,T.rubripes and M.mercenarias with F.chinensis.The growth effects of T.rubripes with M.mercenarias were analyzed,and the culture benefits were calculated respectively.The stocking quantity of F.chinensis under the three modes was fixed,with the initial specification of 20000 ind./kg and the stocking density of 6 kg/hm^(2).At the same time,the stocking density of T.rubripes and M.mercenarias was also selected under the three modes with the highest efficiency.
