江苏沿海渔场辽阔,沿岸水域生物种类众多,生物量十分丰富。然而,长期以来部分附着性生物给该区定置张网生产带来了影响,增加了诸多不利因素。在历年气温较高的夏季,网线表面作为大型生物附着基质的微生物膜形成迅速,不同种类的大型附着生物个体对有限的网衣面积反复占有,相互重 There is a vast coastal fishery in Jiangsu Province. There are many biological species in coastal waters, and the biomass is very rich. However, for a long time some of the adhering organisms have had an impact on the setting of netting in this area, adding many unfavorable factors. In the summer with a high temperature over the years, the microbial membrane formed on the surface of the network as a large-scale biological attachment substrate is rapidly formed. Individuals of different types of large-sized attached organisms repeatedly occupy a limited area of ​​the mesh,
