Maybe a saltwater fish bio could comment, but I think at least PS lingcod are doing fine.

I know the rockfish are in trouble, but I understand that the ling population is way up compared to ten or even twenty years ago.

I suspect part of the reason the rockfish are in such trouble is that the lings were protected (and allowed to prey on rockfish unmolested)for almost a decade, while rockfish were overharvested (that and the rockfish have much longer lifecycles).

It looks like it took about 1 lingcod generation (~15-20 years) to recover lings from the overfishing of the late 70s and early 80s. I suspect with the current regs, the rockfish will come back in about 1 generation as well. Unfortunately 1 rockfish generation is more like 50 years.

I think with the restrictive regs, the lings will be ok. Now if we could just get the divers to stop killing the oversize spawner females, I think PS ling managment would be quite good.
