Abstract
Fyke net captures of both the shortfinned eel, Anguilla ausrralis Richardson, and the longfinned eel. A. dieffenbachü Gray, were recorded over a 4‐year period in Lake Pounui. New Zealand. Eel activity measured as catch per unit effort (CPUE) was correlated to 36 indices of water temperature water level, barometric pressure, amount of light at night and lunar period using multiple regression analysis. For longfinned eels, water temperature was the only individual parameter significantly related (P2= 0.29. P 2= 0.51. P<0.001.
