[quote=JoJo]Would be interesting to see what would happen if a river with decent habitat and a wild fish population still somewhat making escapement was no longer planted with hatchery fish as a test case. More than likely it would take years to get any results. But I think we would have a better understanding of what affects they have.[quote]


Unfortunately, the net and troll fisheries in the bay just outside the mouth of whatever river you tried it in would skew the real results...
