摘　　要：利用闽南-台湾浅滩渔场1986-1997年遥感海表温度资料与同期灯光围网渔业信息船的渔捞日志,对该渔场海表温度与鲐鲹鱼类群聚资源年际变动之间的关系进行了初步的探讨。结果表明,沿着25.5℃等温线形成一个中心渔场,空间位置的年际摆动范围在纬向上小于0.5°;海表温度距平(SSTA)与鲐鲹鱼类资源指数的变动在年际尺度上没有关联,但在年代际尺度上存在一定关联,1988年起SSTA摆动的频度和幅度在正值态大于负值态,而资源指数则呈现逐步上升的趋势。Logbooks of light purse net fishing during the period from 1986 to 1997 in the Minnan-Taiwan Bank Fishing Ground along with the concurrent AVHRR remote sensing sea surface temperature （SST） were analyzed. The location of fishing ground center fluctuated from year to year, generally distributing along the 25.5 degree C isotherm. The SST anomaly （SSTA） data demonstrated the possibility that there was one shift from cold to warm regime occurring in 1988,while Catch Per Unit Effort （CPUE） of Chub Macherel and Round Scad was likely to show a tendency of gradual increase after 1988. However, the proportion of warm water species relative to warm temperate species changed only after 1992.
