Rockfish is far better than halibut but after 6 months in the freezer it is garbage.
I wouldn't call it garbage, but I know what you're talking about. It gets a strong fishy taste to it after being in the freezer too long, and "too long" is pretty short, compared to salmon and halibut. Ling cod seems to deteriorate pretty quickly, too.
Our problem is that we are spoiled with fresh fish (and shrimp) all summer, and then we are disappointed when we have to slum the freezer the rest of the year.
Maggie, rockfish (especially the bigger ones) get really chewy when you overcook them. Cook them just long enough so that the top of filet just starts to flake apart under the broiler. That's it, no more!
