人工鱼礁材料生物附着效果的初步研究

人工鱼礁材料的生物附着效果试验表明,投放3·5个月后,试验材料附着生物种类有17科20种,优势种为网纹藤壶;投放20·5个月后,其附着生物有31科36种,优势种为翡翠贻贝。比较不同试验材料的生物附着效果,混凝土板、木板、铁板和塑料板的附着效果较好。同种材料,表面粗糙的混凝土板、涂有红丹防锈漆的木板、涂有绿漆的铁板和灰色塑料板的附着效果最好。由于大多数废旧渔船为铁木或钢筋混凝土结构,这些废旧渔船均适宜用作人工鱼礁建造材料。

Preliminary study on effects of accrete organisms of artificial reef material

The experimental effects of accrete organisms of artificial reef material were put up. The results showed there were 20 species of 17 families with dominated by Balanus reticulates on the artificial reef material after 3.5 months of immersion, and 36 species of 31 families with dominated by Perna viridis after 20.5 months of immersion. The accrete effects of concrete slab, wood board, iron plate and plastic board were better than other material. The accrete effects of rough concrete slab, wood board with rustproof paint, iron plate with green paint and gray plastic board were the best among the same material.As being made from iron-wood or ferroconcrete, the most fishing vessels are suitable used for artificial reef material.
