摘要

Despite the absence of rainfall or of any rise in river water level, the seaward migration of Japanese silver eels frequently occurs after the passage of a 'dry depression', suggesting that the migratory behavior of the eels is influenced by the atmospheric depression rather than by rainfall or elevated water level, as is usually thought. Our analyses showed that seaward migration of silver eels takes place mainly during the new moon in autumn to winter as water temperature decreases, sug- gesting the possibility that their migratory behavior depends on at least 3 independent environmen- tal factors: water temperature, lunar phase of an atmospheric depression.
