Inland Fisheries Ireland (IFI) have advised that coarse fish and pike have been present in the Lough Corrib catchment for many years. IFI regularly monitor fish populations in several waterbodies in the Lough Corrib Catchment to assess their composition, abundance, age structure and ecological status. Lough Corrib, along with six other large freshwater lakes in the west of Ireland are currently being managed preferentially as recreational salmonid fisheries and the information gathered through IFI surveys is used as an ecological indicator and to inform fishery management decisions. Coarse fish and pike stocks are managed at some locations.
The conservation bye-laws referred to in the question, which currently underpin the protection and management of coarse fish in Ireland, are currently under review. A public consultation process has recently closed and I look forward to the review process concluding in due course.
