Fish 4 all, but if you contain the geneticts on your end to one system, and mother nature takes care of the rest with stray rate ranging from minimal to 30%, then an inbred condition should never be reached, and we should never see genitic failure. Our finned fish of today resemble our hatchery turds moreso then the Wild Native fish of the past, Sure some are still carrying the majority of the genes of there wild ancestors, But most appear to be severly diluted. As was stated before if they hit the gravel they become hatchery wild, there returning offspring are Native wild, and the delution has begun. So i think the majority would fall under Hatchery wild opposed to an other .
