Wild fish crossing with hatchery fish in the wild is never a good thing especially in terms of increasing the wild fitness.
IT is however commonly used to improve the fitness of hatchery strains. Several of the steelhead and salmon hatcheries infuse wild genes into thier hatchery stock to improve them. When used this way I support it as it reduces the impact hatchery fish have on wild strains if/when hatchery x wild crosses occur.
