生态混养是一种模仿生物生态系统的科学水产养殖模式。在同一海水池塘中养殖蟹、虾与贝类,可以充分利用养殖水域空间与池塘滩面,实现水中有虾、水底有蟹与泥中有贝类的全方位、立体化养殖模式。蟹虾贝混养,还可实现残饵与粪便肥水、有机碎屑与肥水培养的单细胞藻类供贝类滤食,? Ecological polyculture is a scientific aquaculture model that mimics a biological ecosystem. Breeding crab, shrimp and shellfish in the same seawater pond can make full use of the aquaculture water space and the pond beach surface to realize shrimp in the water and a full-scale and three-dimensional breeding mode in the bottom of the pond. Crab shrimp mixed breeding, but also to achieve bait and faeces fertilizer, organic detritus and fertilizer cultured single-cell algae for shellfish filter food?
