I'll bite. It says returns have been lower and they risk not making egg take. Then it reopens to coho only once they go out a "broodstock" enough fish to make egg take. That seems to be an additional reason for additional closures. The fishery remained constrained by wild fish even after egg take was acheived, otherwise they would've open kings again.

And, on a typical year, WB has far more hatchery fish available harvest than there are wild impacts available to prosecute the fisheries. Where is my analysis off?
