Store whole rockfish in your freezer until you're ready to use them, then thaw as many as you need. We do not recommend thawing and refreezing raw fish.

Whole Pacific rockfish excel in whole-fish applications. They can be roasted whole in a salt crust, simply baked in the oven lightly seasoned with salt and lemon, or poached. They can also be cut into fillets, which will cook faster and are great for serving on individual plates rather than as a whole fish on a platter. Rockfish is also a good choice for making ceviche.
Prior to cooking, this fish should be cleaned and scaled.

Warning: Rockfish’s top fins have sharp spines. Care must be taken while cleaning this fish not to cut yourself. The safest way to do this is simply to take kitchen shears and clip the spines off the top of the fins before doing any other cleaning, but this will change the look of the fish if you are presenting it whole.
