Last weekend I went out halibut fishing, it turned into rockfish and red snapper fishing because we couldnt keep them off the blasted halibut hooks.
At least the snapper were tasty...
I've tried big circle hooks that I thought would be too big for them, the rockfish ate them anyway.
I tried keeping it 2-6 feet off the bottom, they hit it anyway.
I tried fishing in the level sand/mud spots a little bit away from the rock piles, they chased after it anyway.
The typical halibut rig I use is a spreader bar with a 1-3lb weight on the bottom and a 650 net cord leader going to a circle hook. Basically a standard halibut rig.
For fun I might put a tampon soaked in herring oil and a light on the spreader bar now and then.
