ON THE POTENTIAL RELATIONSHIP OF FISHING GROUND POSITION SHIFT WITH THE VARIABILITY OF SEA SURFACE TEMPERATURE IN THE TAIWAN STRAIT IN SUMMERS OF 1997 AND 1998

针对台湾海峡中上层鱼类中心渔场的变动问题 ,通过对1997～1998年夏汛期间AVHRR遥感表层水温 (SST)的分析 ,发现相应于北部和西南部中心渔场在1998年范围缩小、南界大幅北移0.5个纬度的现象 ,1997年渔场南界一线的SST ,在1998年升高可达1℃。推测SST的这种变化 ,是中心渔场出现明显位移的原因之一 ,并且与此期间发生的ElNino事件可能存在着某种关联。The areas of fishing grounds for the upper water species located in the northern and southwestern of the Taiwan Strait were found much smaller in summer of 1998 than in 1997. From 1997 to 1998, the southern borders of them shifted northward as far as 0.5 degree latitude. AVHRR SST in this region was observed, showing that mean SST along the southern borders of 1997 grounds increased in 1998. Mean SST could be 1 ℃ higher in 1998 than in 1997 at most. Thus warming of water was suggested to be one of the reasons resulting of the shift of fishing ground positions. The El Nino of 1997 to 1998 was suspected to be somewhat responsible for this phenomenon.
