2018年春季浙江梅山海域春季渔业资源调查研究

Status of Fishery Resources Near Meishan Island in Zhejiang Province

依据2018年4月梅山水域渔业资源调查资料,研究梅山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24种。调查海域的渔业资源重量和尾数密度最大种类都是虾类。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 data from one oceanographic censuses in the Meishan island waters in April of 2018, this paper discussed the spatial - temporal distribution of fish density involved in some impact factors such as advantages, as well as diversity. The results showed that there were 24 kinds of 4 species in Spring. The largest species of fishery resource weight and tail density in the surveyed sea area is shrimp. The dominant species in the survey sea area are common species along the East China Sea. The biodiversity, abundance and the evenness index distribution were all low.
