在室外养殖池塘中进行异育银鲫和网箱养草(菹草)的混养实验,旨在通过监测室外池塘养殖系统中水体主要理化因子,探讨网箱养草对养殖水体主要营养盐的去除效果。结果表明:在本次试验的鱼草共生系统中,网箱养草对水体具有明显的净化效果,能有效去除水体中的N、P等营养性物质。 The polyculture experiments of allogynogenetic crucian carp (Carassius auratus gibelio) and net cage (Agkistrodon acutus) in outdoor ponds are designed to monitor the main physical and chemical factors of the water in outdoor pond aquaculture system and to investigate the effects of cage culture on the main nutrients of aquaculture water Removal. The results showed that in this experiment, the net culture of aquaculture grass had obvious purifying effect on aquatic plants, which could effectively remove N, P and other nutrients in water.
