You wouldn't have remove ALL the fish, Aunty.

There's still a quota. X fish is X fish. If there is not a quota, one can easily be made. One can also and easily manage how many fish are taken and when. IE, if the runs don't meet for the expected forecast, don't take all the fish at once. Spread it out over time and if the numbers do add up, STOP taking fish out of the ladder.

Instead of killing the X fish in a gillnet + the Y ESA fish and the Z other fish, the harvesters just take their marked X fish and call it good.

Of course, I don't think there's a commercial or tribal person out there willing to just show up with a tote to collect their permitted fish. There's something about the "killing a fish" factor that everyone seems to like.
