Abstract
The physical features of the Crumlin catchment, a small sea-trout fishery in Co. Galway, are described. Its sea-trout stock is examined and found to be typical of others in the region: the fish are slow growing in the sea, poorly conditioned, mortality in the stock is high and the fish have a low weight at capture. Fishery statistics date from 1896. The main influence on the numbers taken by anglers appears to have been the two wars. Individual catch weights do not show any inverse relationship with catch numbers of the kind that has been reported already in the vicinity. Catch per effort has not altered in keeping with any identifiable long-term trend but is within the range recently reported elsewhere in the region. Regulations designed for the protection of smolts in past years also protect about 20% of post-smolts (finnock) currently captured. Yield from Crumlin has most in common with output from a small neighbouring fishery. It is tentatively suggested that sea-trout production from the Connemara catchments is dependent primarily on the physical features of the systems concerned.
