Genetic introgression from stocked adult northern pike Esox lucius to a wild self‐recruiting population was detected in a large river system and some stocked E. lucius survived up to two spawning seasons and dispersed over several kilometres in the river. Moreover, the catch rate of stocked E. lucius by anglers was low (9.6%), hence suggesting that the efficiency of stocking activity is questionable.
