I am advised by Inland Fisheries Ireland (IFI), which manages the Lough Aderra fishery, that the fishery there is a “put and take” fishery and reared rainbow trout are stocked periodically throughout the year. The fishery operates throughout the regular angling season up to the end of September each year when most trout fishing ceases. Put and take rainbow trout fisheries are among the few types of fishery with potential to operate through the winter. However, while the Aderra Fishery was previously operated through the winter, IFI advises that the use of the facility was limited. On that basis, extending opening beyond the traditional season was not economically viable due to the significant maintenance and stocking requirements and the lake is currently closed to angling.
