Abstract
This paper relates daily mean seawater temperature and daily rainfall in northern Taiwan to the catches of A. japonica elvers during a two-y ear period. The results indicate a positive (P<0.05) relationship betw een rainfall and elver catches and a negative (P<0.05) relationship be tween seawater temperature and elver catches. Peaks in elver catches g enerally coincided with peaks in rainfall and minimums of temperature. Rainfall is clearly as important in affecting elver catch as is seawa ter temperature, which was previously regarded as the key factor.
