摘要
分析了建设人工鱼礁对渔业资源增殖的影响,并以广东省汕头市人工礁区渔业资源调查情况为例,分析建礁前后人工鱼礁区渔业资源变动情况。结果表明,投礁后礁区海域游泳生物的资源密度明显比投礁前高,增加了25.63倍;礁区海域各类资源种类均比投礁前丰富,总种数由投礁前的23种增加至41种,比投礁前增加了0.78倍;表明人工鱼礁投放后,鱼礁区集鱼效果明显提高、群落结构明显改善,人工鱼礁建设取得了明显的增殖效果。并对我国工人鱼礁事业的发展提出建议。
The paper analysed the effect on fishery resources multiplication of artificial reefs. The background survey and tracking survey of artificial reef area in Shantou city were carried out in 2003 and 2007, respectively. The results indicated that after the deployment of artificial reef, the biomass density of fishery resources increased by 25.63 times, which were much higher than before. The resources species was much more abundant, total number increased from 23 to 41, which increased by 0.78 times. In conclusion, the results indicated that the fishery resources of artificial reef site had been improved, and the community structure and habitat environment had been significantly improved. The ecological and economical effects of artificial reef had been proved to be good in its beginning. Finally, the paper provided some constructive suggestions to the artificial reef development in China.
