摘要
利用2019年8月—2020年4月的3个航次底拖网调查资料,对南黄海2个水产种质资源保护区大型底栖动物的种类组成、优势种组成、物种多样性及其季节变化进行研究,并分析了2个保护区大型底栖动物的群落结构现状。结果表明:2个保护区3个季节调查共获得大型底栖动物78种,其中甲壳动物最多(30种),其次是鱼类25种,软体动物12种,棘皮动物10种,多毛类1种;保护区的优势种较为丰富,对虾保护区优势种季节更替率较小,银鲳保护区优势种以甲壳类为主,经济种类较多;夏季2个保护区之间物种多样性指数差异显著(P<0.05),大型底栖动物群落总体上相对稳定。本研究为近岸水产种质资源保护区生物多样性研究提供了基础数据,为渔业资源保护及可持续利用提供技术支撑。
The community structure and species diversity of macrobenthos in two national aquatic germplasm reserves of South Yellow Sea were studied based on the trawling macrobenthos of three seasons from August 2019 to April 2020. A total of 78 macrofauna species were identified,including 30 species of crustaceans,25 species of fishes,12 species of mollusks,10 species of echinoderms and 1 species of polychaete. There was no seasonal variation in dominant species in the Reserve of Chinese Shrimp. Crustaceans were the dominant species in the Reserve of Silver Pomfret. Species diversity index differed between the two reserves only in summer( P < 0. 05). Our results provide basic data for the biodiversity research of reserves and technical support for the protection and sustainable utilization of fishery resources.
