浙江路桥附近海域春秋季渔业资源调查

目的]调查浙江路桥附近海域春秋季渔业资源。方法]基于2016年11月路桥附近海域渔业资源调查资料,研究路桥附近海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]春季渔业资源生物共4类35种。调查海域的渔业资源重量和尾数密度最大种类分别为鱼类和虾类。调查海域优势种均为东海沿岸常见种类。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。结论]研究结果可为浙江路桥附近海域的生态监测、评价提供依据,也为该海域海洋资源的可持续开发与利用提供科学依据。

Investigation on Fishery Resources in the Adjacent Sea Area of Luqiao in Zhejiang Province

Objective] To investigate the fishery resources in spring and autumn in the adjacent sea area of Luqiao in Zhejiang Province. Method]Based on the survey data of fishery resources in the adjacent sea area of Luqiao in November of 2016,the spatial-temporal distribu-tion of fish density in the adjacent sea area of Luqiao was studied,and the effects of dominant species, bio-diversity and other factors on the distribution of fishes were analyzed.Result]There were 35 kinds of 4 species of fishery resources in spring.Fishes and shrimps had maximum fishery resource weight and species density in survey sea area.The dominant species in survey sea area were common types in the coastal area of the East China Sea.The biodiversity, abundance and the evenness index distribution in survey sea area were all low.Conclusion]The re-search results can provide basis for the ecological monitoring and evaluation in the adjacent sea area of Luqiao in Zhejiang Province and provide scientific basis for the sustainable exploitation and utlization of fishery resources in this sea area .
