浙江省朱家尖附近海域渔业资源调查研究

Survey on Fishery Resources Near Zhujiajian Island in Zhejiang Province

依据2016年3月朱家尖水域渔业资源调查资料,研究朱家尖水域鱼类密度的时空分布,分析优势种、生物多样性等因素对鱼类分布的影响。结果表明,春季渔业资源生物4类33种。调查海域的渔业资源重量和尾数密度最大种类分别是鱼类和虾类。调查海域优势种均是东海沿岸常见种类。调查海域渔业资源生物多样性指数、丰度指数和均匀度分布水平偏低。

Based on the survey data of fishery resources in Zhujiajian island in March 2016,the spatial and temporal distribution offish density in Zhujiajian island was studied. The effecls of dominant species,biodiversity and other factors on the distribution offish species were analyzed.The results showed lhal there were 33 species of 4 species in spring fishery resources.The species with the largest weight and mantissa density in the survey area were fish and shrimp, respeclively. The dominant species in the survey area were all common species along the coast of East China Sea.The biodiversity index,abundance index and evenness distribution of fishery resources in the surveyed waters were low.
