An electrofishing survey of Lough Erne spawning streams indicates a continued decline in the populations of juvenile salmonids. This is particularly the case with salmon stocks, which are now seriously depleted or absent from the sampled areas. This finding complies with the recorded decline in the adult salmon escapement to the Erne system. Stocking operations of both salmon and trout appear to have been successful in boosting recruitment only on a localised basis.
