Foraging specialisms influence space use and movement patterns of the European eel Anguilla anguilla.
A fixed receiver array was used to examine the movement patterns and space use of the European eel Anguilla anguilla in an oligotrophic Irish lake between July and September. We assessed home range size, temporal change in spatial behaviour and activity patterns of broad-headed (n = 11) and narrow-h...
