The Eel Monitoring Programme (EMP) at Inland Fisheries Ireland uses fyke net surveys to assess yellow eel populations in lakes, main channel rivers, canals, transitional waters and lagoons. For further information on the methodology used in the surveys please contact IFI, methodology includes the use of chains of 5 nets, along with repeating historical surveys with chains of 10 nets. This dataset contains data including year of sampling, waterbody name and type, catchment name and river basin district (RBD). The Erne catchment is monitored as part of the North West International River Basin District (NWIRBD) as an eel management unit under Irelands Eel Management Plan in collaboration with agencies in Northern Ireland.Catch data on yellow eels for surveys are presented, including, numbers of eels captured/measured and summarised length and weight results for summer fyke netting European Eel surveys (yellow eel life stage) along with length frequency breakdowns of catches. Net*Nights are calculated by multiplying the number of nets set by the number of night that the nets were allowed to fish. The European Eel Fyke Net dataset can be viewed and downloaded here: European Eel Fyke Net DataMap contains data produced by the Environmental Protection Agency.
