Making sure to avoid halibut (yes they do roam down in 2-250fa's now and then) and anything like the other Red Rockfish mentioned that can be found down deep.
We can't retain any of those but the Thornyheads so, I work to keep it clean.
So maybe that has something to do with it. I'd say the largest I've seen is a 10 lber now and then, the avg being .75 lbs for the season
Do you guys in the Sound run into the other Reds, Shortraker, Rougheye's?
When I fished more up on the Albatross bank south of Kodiak those were much more common, but not much out west.
We do get into the other rockfish, but not much when targeting sablefish. We primarily fish sablefish from 280-320 fathoms, and in those areas we tend to get into more thornyheads than the others. When targeting a mix of halibut and sablefish we might get as shallow as 200-250 fathoms, and there we get far more shortrakers and some rougheye. And yep, the halibut do range deep. We still pull in decent numbers of halibut under 300 fathoms or deeper. Since my brother, father, and mother are all IFQ holders, though, we can retain them.
As for numbers, we'll only get 5-10 thornyheads per 3 mile set, so though our size appears to be larger, your numbers are significantly higher.
