为了全面掌握外伶仃人工鱼礁区礁体投放前后人工鱼礁对礁区水环境理化要素、海底表层沉积物、环境生物及渔业资源的影响状况,评价人工鱼礁的生态与环境功能,评估人工鱼礁的集鱼效果,对该人工鱼礁区进行了投礁后综合调查。结果显示:投礁后礁区渔业资源种类明显比投礁前丰富;投礁后礁区各类渔业资源的资源密度明显比投礁前高;礁体附着生物更加多样化,礁区资源养护、增殖效果日趋明显。
In order to fully understand the influence of artificial reefs before and after the artificial reefs of artificial reefs in Lingdingding on the physical and chemical elements of water environment, the surface sediments, environmental organisms and fishery resources in reefs, evaluate the ecological and environmental functions of artificial reefs, Fish reef fishing effect, the reef artificial reef area after reef survey. The results showed that the species of fishery resources in the reef-reef area after reef-reefing were significantly more abundant than those before reef-reefing. The resource density of all kinds of fishery resources in Reef reef area after reef-reefing was obviously higher than that before reef reef. The reef attachment organisms were more diversified, Increasing effect of proliferation is obvious.
