Quote from Smalma:
"The reason that hatchery fish don't bite is two fold. The first of course is that we exert a high selective pressure against the best biters (we kill them all before they spawn). The second is that the longer the fish is in the river the more likely it is that it will be caught and killed. Therefore the most successful spawners (those that get to the hatchery) are those that arrive at the river in an advance state of sexually maturity (not likely to bite) and zoom up the river.

Simple solution - Release Hatchery Fish, only wild fish may be retained. J/K

Perhaps a user controlled system that selects towards the better biting hatchery spawners would work.

Simply ask anglers to tag or mark the hatchery fish they C&R and reward them with two bright fish from the collection traps for each fish released.

Might be some who cheat but handing them some surplus fish beats having them poach or snag and this seems to be a better use for surplus fish than the catfood factory.
