摘要
1988年8月至1989年7月在大亚湾鱼礁区进行附着生物调查研究,记录79种生物,大约有82.7％的生物种类是鱼礁区鱼虾的饵料生物(包括35种不带壳和32种带壳的饵料生物),有17.3％的生物种类为非饵料生物。礁区附着生物种类多,附着量大,生长迅速,投礁半年后100％被生物覆盖,附着厚度30mm,附着量达17.487kg/m^2。礁区生物一年四季都能繁殖附着,主要附着期4—10月,高峰期7、8、9三个月,是投礁的最佳时间。
From August 1988 tc July 1989, attaching organisms in the fish reef area of Daya Bay were investigated. 79 species were recorded. About 82.7% of these are bait organisms of fish and shrimps in the fish reef area, including 35 species of nonshelled and 32 species of shelled bait organisms. 17.3% of the species are not bait organisms. The attaching organisms in the fish reef area were numerous in species, large in biomass and grew rapidly. Half a year after the reefs were cast, they were 100% covered by the organisms, with the thickness 30mm and the biomass reaching 17.487 kg/m^2, The reproduction and attachment of attaching organisms in the reef area occurred all the four seasons of the year. The major attaching period was July, August and September, which can be selected as the best period for the cast of the reefs.
