摘 要:为进一步加强对黄河口及其邻近海域渔业资源状况的认识并推动保护措施,通过2019年4月份、8月份和9月份在该海域开展的3航次渔业资源调查,鉴定渔获物79种、27.67万尾,渔业资源重量为2170.71 kg。结果显示,研究海域生物多样性相关指数均呈较大幅度波动状变化,生物种类数春季较往年偏高,夏季低于往年。分析结果可知,该海域生态状况有所恢复,生物多样性水平较往年有所提高,但关键种的缺位、高营养级生物的不足等问题依旧突出,夏季资源呈现下降趋势。In order to further strengthen the understanding of the fishery resource status of the Yellow River Estuary and its adjacent waters,and to promote protection measures,this article conducts three voyages of fishery resource surveys in the waters in April,August and September,2019.79 species and 276700 tails are caught,and the weight of fishery resources is 2170.71 kg.The biodiversity-related indices of the seas fluctuates greatly.Compared with the previous years,the number of the biological species is higher in spring and lower in summer.The analysis results show that the ecological conditions of the sea area have recovered and the level of biodiversity has increased,but the lack of key species and the shortage of high-trophic organisms are still prominent,and summer resources are showing a downward trend.
