| 摘要: |
| 为了解石臼港近岸海域游泳动物的种类组成及变化情况，探明该海域游泳动物群落结构及季节变化，本研究根据2016年11月（春季）在石臼港区近岸海域进行的游泳动物拖网调查资料，分析了该海域的游泳动物资源群落结构特征，并结合2016年5月调查数据分析该海域游泳动物的季节变化。本次调查在该海域共捕获渔业资源种类64种，尾数资源密度为118.22×103 ind./km2，质量资源密度为447.56 kg/km2。优势种为戴氏赤虾（Metapenaeopsis dalei）、尖海龙（Syngnathus acus）、短蛸（Octopus minor）、口虾蛄（Enedrias fangi）。该海域秋季游泳动物种类数量明显高于春季，但资源尾数密度和资源质量密度远低于春季。 |

| Abstract: |
| In order to understand the species composition and changes of nekton in the coastal waters of Shijiu Port,and to explore the community structure and seasonal changes of nekton in this area,the situation of fishery resources in the sea area was analyzed by the data of bottom trawl surveys in Shijiu Port in November 2016,and the seasonal changes nekton in the sea area were analyzed in the survey data in May 2016.In this survey,64 species of fishery resources were captured in the sea area.The individual density was 118.22×103 ind./km2,and the weight density was 447.56 kg/km2.The dominant species in this survey were mainly Metapenaeopsis dalei,Syngnathus acus,Octopus minor and Enedrias fangi.It shows that the number of species of nekton in this sea area in autumn is significantly higher than that in spring,but the individual density and weight density of resources are much lower than that in spring. |
