威海近岸人工鱼礁布设对生物资源恢复效果
发布时间：2018-09-04 15:11
【摘要】：为了解人工鱼礁投放对区域内海洋生物资源恢复效果,于2013年3月至2014年1月在北黄海近岸人工鱼礁投放区进行调查。结果显示,该海区发现浮游动物53种,其中优势种为浮游桡足类。夏秋季底栖生物幼体成为季节性优势种。游泳动物共发现14种,主要为常见的礁区鱼类。底栖动物共12种,其中棘皮动物海燕为绝对优势种,为近岸养殖生物的主要敌害生物,主要的底栖资源优势种为虾蟹类与软体动物。投礁区的浮游动物与游泳动物物种数明显多于未投礁区,表明人工投礁有助于生物群落的恢复,提高生物多样性,改善区域生态系统。但该海域大型底栖藻类较少,还应进一步对大型底栖藻类增殖以提高海域初级生产。
[Abstract]:In order to understand the effect of artificial reef on the restoration of marine living resources in the area, a survey was carried out in the coastal artificial reef area of North Huang Hai from March 2013 to January 2014. The results showed that 53 species of zooplankton were found in this area, among which the dominant species were planktonic copepods. Benthos larvae become seasonal dominant species in summer and autumn. A total of 14 species of swimming animals were found, mainly common reef fish. There are 12 species of benthos, of which echinoderm Haiyan is the dominant species, the main enemy and pest of coastal aquaculture, and the dominant species of benthic resources are shrimps, crabs and molluscs. The number of zooplankton and swimming animal species in the reef area is obviously more than that in the non-reef area, which indicates that artificial reef throwing is helpful to the restoration of biota, the improvement of biodiversity and the improvement of regional ecosystem. But there are few macrobenthos in this area, so it is necessary to increase the primary production of macrobenthic algae.
