I've been catching and freezing sockeye for several years with good results. Basically, and i'm sure it's like everyone else, I catch, fillet, rinse, vac-pack and freeze.
My question is can i add anything to the raw salmon in the vac bag before i seal and freeze? What i was thinking about doing is adding teriyaki sauce, hot sauce, salad dressing or even a dry rub. Has anyone tried this? Seems like it should work, but i'm concerned about food safety (duh) and that perhaps the added ingredients will degrade the fish.
