Sammanfattning

From 475 eels individually marked with floy tags, of which 180 had an additional spot of alcian blue, 142 tags were recovered during a 2-year release-recapture programme, but alcian blue spots were not detected. The marked population declined by c. 95% per year (either through death or tag loss); tagged eels did not grow but lost weight; no trap avoidance could be detected. [t is concluded that these tagged eels in poor condition did not suffer from winter mortality, and that during summer they moved around very actively.
