Then you understand that it is not very likely for a composite population made up of 90% hatchery fish being fished at a rate that can't be sustained by the natural population to actually show any increase in productivity. Abundance, of course, can be increased by the contribution of the hatchery component of the population. What is being accomplished by managing overall PS fisheries based on exploitation rate limitations on this particular population? I suggest again, that this entire approach is a sham.
