This dataset is used to examine a 35 year yellow eel survey to determine relative abundance trends while accounting for survey design, and important physical and operational covariates. Chains of ten, or sometimes 5, fyke nets were fished usually at fixed sites in four lakes on a catchment in the west of Ireland. Captured eels (10,474) were counted for each trap, and weight was recorded for each chain of nets (5,515 net nights fished). Surveys were carried out by Marine Institute staff, and in 2009 and 2010, in collaboration with Inland Fisheries Ireland. The survey was initiated in 1987 to establish a baseline for the eel stock in Burrishoole. The survey was continued as part of the core monitoring programme and has also been integrated into the National eel Monitoring Programme under the EU DCF. The data are in 3 sheets; Catch data for each net trap and chain of nets, eel measurement data, and survey net location and depth data. Suggested Citation: Poole, R. (2023).
