Aunty,

Do you honestly think it matters how a fish from an endangered run dies? It makes no difference whether its caught in a gill net, or a tangle net, or by a charter boat client, or of hooking mortality under CNR it is still dead.
There have been years of no fishing, but the fish didn't rebound. The reason is because overfishing isn't the problem habitat devastation is the problem.

Banning all netting tomorrow wouldn't solve the problems on the Columbia. Sombody else would step in to catch those fish by whatever means necessary.
However, removing dams might help quite a bit. Compare the fraser to the columbia. The big difference is the state of the habitat not fishing pressure.

Why focus on a solution that won't work?

Don't get me wrong, I think gillnets are terrible from the fishes standpoint, but not nearly so terrible as bonneville or grand coulee.

Like I've said before, Overfishing is a temporary problem. Habitat destruction is nearly permanent.
