摘要
以 1990～ 2 0 0 3年东海区渔业资源动态监测资料为依据 ,分析了东海北部、黄海南部水母资源的动态及其与渔业产量的关系。结果表明 ,近年来 ,水母数量一直维持很高水平的大型水母为霞水母和口冠水母 ,远高于 2 0世纪 90年代初期的水平 ;这些水母分布在 2 8°30′～ 34°N、江浙沿海至 12 7°E ,以 7～ 9月份的相对资源密度指数为高 ;东。
Based on the survey data conducted by Fishery Resources Dynamic and Monitor Net of the East China Sea Region during 1990 to 2003, the dynamics of macro-jellyfish resources and their relationship with fish catch in the northern East China Sea and southern Yellow Sea were analyzed. It showed that the biomass of macro-jellyfish in recent years was much greater than that in the early 1990s and the dominant species were Cyaneaspp. and Stomolophusspp.; they distributed in the sea area of 28°30′N-34°00′N, from the shore of Jiangsu and Zhejiang to 127°00′E; the comparative resource density index was high during July to September; the great increase of jellyfish was consistent with the decrease of fishery resource density in the East China Sea and the Yellow Sea.
