Inland Fisheries Ireland is today re-opening the Galway Fishery in Galway city and the Erriff and Moy fisheries in Co. Mayo.
The three State-owned fisheries had been closed since Tuesday of last week due to high water temperatures.
IFI closed the fisheries so that cold water fish species did not suffer potentially lethal angling-related stress, in addition to stress caused by water temperatures above 20 degrees.
Multiple temperature readings below 18 degrees have since been recorded at the three fisheries
