Catch-and-release methods ensure that trout stock have a greater chance of survival within the freshwater lake.
Dr Cathal Gallagher, Head of Research and Development at IFI, commented: “The trends, over the four decades studied in the research, were mostly positive regarding the abundance and size of trout in the lake and its ecosystem.
“Respondents commented they now believe the lake is currently fishing well.
“However, some expressed concerns about threats to Lough Sheelin’s trout stocks, including pollution, pressure from angling activity, poor water quality, and protection of fish.
“This research highlights the growth in awareness of fish conservation among anglers.
“Seasoned fishers on Lough Sheelin have a deep understanding of the lake’s surrounding ecology that’s been developed through long-term interactions with the natural environment.”
