The shelf life of rockfish depends on the species, product form and harvest method. On average, fresh fillets have a shelf life of 5 to 7 days at 32°F with ice, with red rock fillets typically keeping better than brown rock fillets (due to lower oil content). Frozen fillets have a shelf life of 9 months at -5 to -15°F.

Rockfish has a sweet, mild flavor, with a flaky, medium-firm texture. It is best baked, sautéed, broiled or poached. Since the flesh tends to flake easily, it is not the best fish for grilling. Try it with a little lemon to bring out the sweet flavor without overpowering. Rockfish is also an excellent fish for use in ceviches.
