摘　　要：本文以 2 0 0 2年东海区渔业资源监测调查资料为依据 ,研究分析了黄的洄游分布、渔业生物学特征和资源量状况。结果表明 ,东海区黄主要分布在黄海南部和东海北部海域 ,高资源密度主要分布在水深 4 0～ 10 0m海域 ,但各调查月份有差异 ;9月份黄个体平均体长为 2 15 .35mm ,优势体长组为 14 0～180mm ,占 5 3% ;平均体重为 397.83g ,优势体重组为 70～ 14 0g ,占 4 5 % ;现存资源量评估结果为 2 0 15t,但实际资源量估计约在 1× 10 4t以上 ,属于有潜在价值渔业。Based on the data obtained from the fishery resource monitoring in the East China Sea in 2002, migration distribution , fishery biology and stock status of yellow goosefish Lophius litulon were analyzed. The results indicated that in 2002,the species distributed mainly in the south of the Yellow Sea and north of the East China Sea, the index of high biomass density occurred chiefly in the sea area at depth of 40 100m, but there were differences in the months of investigation ; in September the average length was 215.35mm, its predominant body length was from 140mm to 180mm, which accounted for 53% and the average weight was 397.83g, with predominant weight from 70g to 140g, representing 45%. The assessment showed that the abundance was 2,015 tons, but the real abundauce was about over 10,000 tons, which will have potential for exploitation.
