after decades of hatchery management, our wild coho stocks are still larger than hatchery runs in puget sound and the coast (check the 2013 forecasts). the same goes for pinks and chums. chinook are a different matter. it also looks like the wild winter steelhead runs are producing more fish than the hatchery system in puget sound and the coast. hatchery fish do not reduce impacts on wild fish, as most saltwater and commercial fisheries are mixed-stock and non-selective. ask early-run wild winter steelhead runs how hatcheries have reduced the impact on them. harvest is based on the number of fish available to harvest, not a fixed number. wild fish cannot be harvested at the same % rate as hatchery fish so when fisheries are targeting hatchery fish the rate is higher for the co-mingled stocks as well. over-harvest is tied to hatcheries.
