摘  要：
本文以东海区 2 0 0 0～ 2 0 0 2连续 3年 4个季节的底拖网渔业资源调查资料为依据 ,分析研究了黄鲫资源数量的时空分布特征及其与水深和水温的关系 ,在此基础上进一步推测了东海区北部海域与中南部海域黄鲫的洄游规律差异。结果表明 ,东海区黄鲫的数量分布不仅有明显的季节差异 ,而且以长江口渔场的南端为界 ,东海区北部海域和中南部海域的黄鲫群体之间存在显著的生态差异。夏季 ,两个群体在吕四、长江口和舟山渔场 2 0～ 95m水深的近海海域集中产卵 ,产卵适温为 19.5～ 2 5 .5℃ ,并有混栖现象。秋季 ,东海北部群体沿东西向作近外海索饵洄游 (水深 :2 5～ 10 0m ,适温 :2 2 .5～ 2 3.5℃ ) ;而中南部群体沿西北向东南海域进行索饵洄游 (水深 :6 0～ 15 0m ,适温 :2 6～ 2 7.5℃ )。冬季 ,北部群体越冬现象不明显 ,适温为 10～ 12℃ ;中南部群体存在明显的越冬行为 ,越冬场主要分布在鱼山、鱼外和舟外渔场。至春季两个群体又均表现出向产卵场聚集的洄游趋势

摘  要：
Based on the data from the bottom trawl surveys in the East China Sea in four seasons from 2000 to 2002, the spatial distribution of Setipinna taty and its relationship between depth and surface water temperature were analyzed, on which the differences of migration between the north and the south central groups were studied. It was found that not only the seasonal distributions of Setipinna taty had great changes, but the ecological characters of the two groups can be partitioned from the north of Changjiang Estuary fishing area. In summer the two groups centered on the Lusi, Changjiang estuary and Zhoushan fishing grounds and mixed in part for spawning where the depth was from 20 to 95m and the proper temperature was 19.5～25.5℃. In autumn the north group migrated for feed from west to east where the depth was from 25～100m and the proper temperature 22.5～23.5℃, but the south central group moved for feed from northwest to southeast where the depth was from 60～150m and the proper temperature 26～27.5℃. In winter the north group did not show apparent overwintering, and the proper temperature was 10～12℃,whereas the south central group had apparent overwintering which mostly centered on the Yushan, Yuwai and Zhouwai fishing grounds. In spring both the two groups had the trend to return to spawing areas.
