Results of Magnetic Tag Recovery Programme in the Mayo Area in 1986

Young salmon are tagged at various locations throughout the country with coded wire tags. They are released at different times of the year, and in various river systems to establish the best time of year and the best locations for release. The majority of the tagged fish are hatchery reared, the only exception being in the Corrib and Blackwater rivers where wild smolts are tagged. All micro-tagged fish are adipose fin clipped. Some hatcheries also use an adipose fin clip to mark their reared fish. Twenty nine thousand net caught salmon were examined at a number of locations in Mayo. All fish with adipose fin clips were screened with a magnetic tag detector. A total of 736 tags were recovered from which it was estimated that rearing stations contributed over 1,300 fish to the north Mayo catch.
