After the hatcheries have gotten their quota of returning fish and they 'close the doors' on the rest of 'em, do they spawn? I know some hatchery and native strains can get mixed but...given no real 'home' water, do they regularly spawn? I've recently debated with a friend about keeping hatchery fish, he felt guilty about keeping his 2nd of the year. I may be wrong (hence the posted Q)but I think it's my duty to keep them out of the way of the native spawners and hell..I pay for hatcheries so why not?! Thoughts, enlightenment? Thanks!!
