These traps will raise some really tough questions if they are successful at releasing wilds/protected fish. The basic question will be why have a hatchery at all if the only harvester will be traps? Until the wild run gets large enough, even release mortality will be important. As the wild run grows, it would be a higher fraction of the run (assuming a rather constant hatchery run). So, to maintain a mixed stock rec fishery you would actually encounter more releasable fish, which would then lower the hatchery fish take when the impacts are reached.
