摘    要:2003和2007年分别对澄海莱芜人工鱼礁区进行了投礁前的本底调查和投礁后的跟踪调查。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,其中,蟹类种数增加最多,增加了1.75倍;在本底调查中没有出现的经济种类龙头鱼Harpodon nehereus和红星梭子蟹Portunus sanguinolentus在跟踪调查中已成为主要优势种;Shannon—Wienver多样性指数(H’)在礁区和对比区均比投礁前有所增加。表明鱼礁投放后,鱼礁区集鱼效果和群落结构明显改善,人工鱼礁建设取得了明显的生态效益和经济效益。

关 键 词:澄海莱芜  人工鱼礁  集鱼效果

Abstract:The background survey and tracking survey of artificial reefs area in Chenghai Laiwu were carried out in 2003 and 2007,respectively.The results indicated that after the deployment of artificial reefs,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.The crab resources sharply increased by 1.75 times after artificial reefs were deployed.Harpodon nehereus and Portunus sanguinolentus,which did not appear in background survey,now became the dominant species in tracking survey.There were high diversity indexes in artificial reefs area and control area in tracking survey.In conclusion,the results indicated that the fish-aggregating effect of artificial reef site has improved a lot,and the community structure and the habitat environment have been significantly improved.The ecological and economical effects of artificial reef have been proved to be good in its first beginning.
Keywords:Chenghai Laiwu  artificial reef  fish-aggregating effect
