No abstracts are to be cited without prior reference to the author.

The aim of the present study was to analyse and compare the feeding behaviour of large eels Anguilla anguilla (> 30 cm total length) in two lakes of different environmental state and corresponding differences in food availability. Investigations were conducted in Lake Großer Vätersee, Germany (clear water, mesotrophic, submerged macrophytes present) and in Lake Vallum, Denmark (turbid, eutrophic, no submerged macrophytes). Fish were sampled regularly by electrofishing. We focused our study on diet patterns.
