摘要
根据渐江南麂以南海区大面本底调查和上马鞍人工鱼礁试验区投礁前一年四季基础调查资料分析研究,确认渐江南部海域可以进行人工鱼礁建设。同时重点论述了上马鞍人工鱼礁试验区的自然条件,认为可以增殖石斑鱼等名贵鱼类资源。
Before the artificial reefs were placed on the sea bottom, the background in the sea area to the south of Nanji Island and in the experimental region of Shangmaan was investigated seasonally from November 1984 to January 1986.According to data on transparency, deposition, bearing capacity of the mud, feeding organisms and commercial fishes, we divide the sea area to the south of Nanji Island into three regions of 10m, 10-30m and over 30m dep-ths respectively. We have also set forth the feasibility, purpose, and reef type recommended for constructing the artificial fish reefs in each of the three regions.The natural conditions and various environmental factors, and seasonal changes, in the experimental region of Shangmaan are also discussed. It is deemed feasible to establish the reef area mainly for the purpose of propaga-ting famous precious fishes such as groupers. Finally, the reef design, reef type, reef placing and the layout of reefs in the Shangmaan region for testing the artificial fish reef are also discussed in this paper.
