Foraging specialisms influence space use and movement patterns of the European eel Anguilla anguilla

摘要: A fixed receiver array was used to examine the movement patterns and space use of European eel Anguilla anguilla in an oligotrophic Irish lake between July September. We assessed home range size, temporal change spatial behaviour activity broad-headed (n = 11) narrow-headed 8) morphotypes. Broad-headed individuals displayed a larger (mean KUD95 (km2):0.296 ± 0.04 S.E.) comparison (km2):0.143 0.02 S.E.). Eel strongly dependent on light conditions. Narrow-headed individuals’ peaks occurred at dawn dusk which exhibited more stable pattern throughout night into dawn, suggesting that eels are crepuscular nature whereas nocturnal. Lunar phase period also influenced within lake. These results provide valuable insights spatio-temporal distribution yellow system, demonstrating individuality foraging has direct influence patterns.
