摘要
为了解如东大竹蛏西施舌国家级水产种质资源保护区渔业资源现状,于2020年4—10月采用底拖网方式开展了调查,分析保护区内渔业资源的种类组成、优势种、物种多样性及其季节变化特征。结果表明,保护区春、夏、秋季共采集渔业资源70种,其中鱼类39种、虾类16种、蟹类11种、头足类3种、其他1种;三疣梭子蟹(Portugal trituberculate)和?(Miichthys miiuy)是3个季节的共同优势种,夏、秋季优势种较为丰富,有小黄鱼(Larimichthys polyactis)、棘头梅童鱼(Collichthys lucidus)和哈氏仿对虾(Parapenaeopsis hardwickii)等经济鱼虾类;夏、秋季物种多样性指数高于春季,各季节渔业资源群落组成较为稳定;保护区的资源量优于邻近海域和南黄海。
The National Aquatic Germplasm Resources of Solen grandis and Coelomactra antiquate in Rudong is located at the South Yellow Sea, with a favorable ecological environment. To understand the fishery resources,an inves-tigation based on bottom trawl was conducted from April to October 2020. The species composition,dominant species composition, species diversity and seasonal changes of fishery resources were investigated, and the status of the community structure of fishery resources are understanded. A total of 70 species of nekton were found, including 39 species of fishes, 16 species of shrimps, 11 species of crabs, 10 species of cephalopods and 1species of other, with the common dominant species of Portugal trituberculate and Miichthys miiuy in the three seasons. There was more abundant dominant species in summer and autumn than that in other seasons and there were many economic fishes and shrimps, including Larimichthys polyactis, Collichthys lucidus and Parapenaeopsis hardwickii. There was higher species diversity index in summer and autumn than that in spring, with stable composition of community in three seasons. There were rich resources in the Reserve than that in the adjacent sea areas and South Yellow Sea.
