Read the regs and know the rules, there is no first two rule in grays ahrbor anywhere, yet.

As for releasin fish, don't handle them, don't let them flop on the bank and release them fast and they survive, I would bet that at least 50% survive to make it to where they are going IF they are not bruised and abused before being let go.

gill hooking a salmon???? I have seen it, 3 times in the last 3 years out of probably 1000 fish. So those 3 fish if released are likely to die if you land them, rip the hook out and release them instead of seeing it can't be kept and cutting the leader; Then maybe 1 of them dies.

As for unmarked hatchery fish, I'd like to know where your info comes from. I have worked 3 different hatcheries in Grays harbor marking Coho and we never released one that was not marked. If they have wild fish in their holding pens they need to let them go unless they keep a certain % to diversify the stock. If they are letting go a certain number of hatchery fish to diversify the gene pool then they are. But I would bet it is a very small % of the total fish released.
