I've caught several ling cod from the south jetty using 1-2oz jigheads with pearl or olive 5" swimbaits. Cast, fall, drag along the bottom. The north jetty is dangerous by foot and better with a boat.
I've also caught black rockfish from the south jetty via boat. A boat is much easier so you can cover more ground, cast easier, use your electronics, and is safer.
I wanted to go on the opener this year but the weather was not the best so I stayed home. I would like to try a swimbait with a weedless hook, size 0 spin-n-glo, and a 1oz weight about 2 foot above the bait. Basically, trying to keep the lure slightly off the bottom to avoid all the snags in the area.
A steelhead or salmon rod will be fine. I usually use a 8' 12-20# rated rod. But I spool up with 50# braid main and 40-50# floro leader. Mostly due to the abrasion resistance and if I get snagged, I can usually pull it free. Several of my snags have actually just been hooking starfish and they hold on to the rocks surprisingly well.
