人工鱼礁竖板不同方形孔径对黑鲷幼鱼诱集效果研究

Study on attraction effect of artificial reefs vertical plate with different square apertures on Sparus macrocephalus

  • 摘要: 建设人工鱼礁是修复海洋生境、养护渔业资源的重要措施。钢筋混凝土鱼礁是常用的人工鱼礁类型,鱼礁竖板 (侧板、内部间板) 方形开孔是钢筋混凝土鱼礁结构设计中主要设计参数,竖板方形孔径大小是影响鱼类诱集效果的重要因素。以人工鱼礁区常见的礁栖鱼类黑鲷 (Sparus macrocephalus) 幼鱼为研究对象,设计制作具有不同方形孔径 (8、16、24、32、40 cm) 的钢筋混凝土人工鱼礁竖板,在实验水池中研究了人工鱼礁竖板不同方形孔径对黑鲷幼鱼的诱集效果。结果表明,对照组空白礁区 (A1) 的黑鲷幼鱼平均出现率为2.56%,放置鱼礁竖板后,B1组 (孔径8 cm) 的平均出现率为9.89%,其次是B3组 (孔径24 m) 的9.01%、B2组 (孔径16 cm) 的7.65%、B5组 (孔径40 cm) 的6.80%、B4组 (孔径 32 cm)的5.25%,鱼礁竖板开孔孔径分别约为黑鲷幼鱼体高 (舒展鱼鳍) 的2、6、4、10、8倍。统计分析说明,5组方形孔径竖板均有一定的诱集效果,其中鱼礁竖板开孔孔径为8 cm的B1组效果最好,但不同孔径之间差异不明显,且无明显规律。

     

    Abstract: Construction of artificial reefs is an important measure to restore marine habitats and conserve fishery resources. Reinforced concrete reefs are commonly-used artificial reefs. The square apertures of the reef vertical plates (Side plates and spacer plate) are made of reinforced concrete reefs. The main structure, the square aperture of the vertical plate is an important factor that affects the fish trapping. In order to observe the attractive effects of different square apertures of reef vertical plates for juvenile black sea bream (Sparus macrocephalus), we used different square pore-size to study the attractive effect on the juveniles. The results show that the average occurrence rate of the juveniles was 2.56% in A1 area of blank reef area in the control group, and that of Group B1 (aperture 8 cm) was 9.89%, followed by 9.01% in B3 (aperture 24 m), 7.65% in B2 (aperture 16 cm), 6.80% in B5 (aperture 40 cm) and 5.25% in B4 (aperture 32 cm) after the reef vertical plate was placed. The fish fins were about 2, 6, 4, 10 and 8 times, respectively. Statistical analysis shows that five groups of square aperture vertical plates have certain trapping effect, among which Group B1 with 8 cm hole diameter of reef vertical plate has the best effect, but there is no obvious difference between the square hole diameters of reef vertical plate.
