Analysis of growth effect and culture benefit of polyculture of Takifugu rubripes,Mercenaria mercenarias and Fenneropenaeus chinensis in pond
Poly culture of different aquaculture species can make full use of material resources in seawa-ter 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.ru-bripes 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 bene-fits were calculated respectively.The stocking quantity of F.chinensis under the three modes was fixed,with the initial specification of 20 000 ind./kg and the stocking density of 6 kg/hm2.At the same time,the stocking density of T.rubripes and M.mercenarias was also selected under the three modes with the highest efficiency.
