【摘要】 2002年4月～12月,对浙江佛渡、象山和大陈海区进行了网箱网衣主要附着生物的定量、定性生物学测定。结果表明:三个试验海区网箱网衣附着生物的种类主要有水螅虫(包括枝螅、管状真枝螅、殖螅等)、海葵、麦杆虫、沟虾、藤壶、贻贝、牡蛎、多管藻、石莼、浒苔以及底栖硅藻类等,其中造成较大危害的主要附着生物种类是水螅虫和海葵。同时,试验基本摸清了三海区网箱网衣主要附着生物种类的季节变化和消长规律。更多还原

【Abstract】 A quantitative and qualitative biological determination of the main fou ling organisms attaching to net pieces was carried out in Fodu,Xi angshan and Dachen water areas durin g the period from April to December2002.The results showed that the main fouling organisms in the three testing areas were hydra(including Obelia sp,Eudendrium capillare,Gonothyrea sp and etc.),Actiniaria,Caprellidae,Gammarid,Barnacle,Mussel,Oys-ter,sea ageal and benthic diatom;am ong which hydra and Actiniaria cause d bigger problems.In addition,the seasonal change and its rule of the ma in fouling organisms were presented.更多还原
