Ocean Perch
The skin is the reason to buy it.
Ocean perch is not a perch. It is Sebastes norvegicus, a North Atlantic rockfish, sold as small skin-on fillets with vivid red-orange skin. The flesh is mild, lean and fine-flaked, and the fillets are thin enough to cook through from the skin side alone.

A North Atlantic rockfish sold in thin, skin-on fillets — mild flesh under skin that crisps hard.
Buy it if
You want crisp fish skin without paying for a premium fillet, and you have one pan and five minutes.
It is a rockfish. Sebastes norvegicus — golden redfish — from the cold North Atlantic, most of it landed by Iceland. Perch proper are freshwater fish in a different order. The name is a market convenience, and it is a shared one: in the US, "ocean perch" also gets applied to Pacific ocean perch, Sebastes alutus, a different rockfish from the other side of the continent.
The skin does the work. Ocean perch skin is thin and a startling red-orange, and it crisps faster and harder than cod's or halibut's. Cook it skin-down in a hot pan and leave it alone — the fillets are thin enough that they are nearly done from the skin side before you would think to turn them.
Thin is the whole design. These are small fish and small fillets. That makes them fast, cheap and forgiving of a weeknight, and it also rules out anything slow: a braise or a stew dissolves them.
Targeted, not bycatch. In the North Atlantic ocean perch is fished on purpose rather than landed alongside something else, which is why the handling is careful; a full Icelandic trip runs one to two days, so the fish is filleted and packed within about a day of the water. The Icelandic fishery is MSC-certified.
Slow-growing fish, hard quotas. Sebastes mature late and live for decades, which is why the North Atlantic fisheries that manage them well run on tight catch limits — and why the ones that did not have taken a very long time to recover.

Ocean Perch vs Sea Bream
Both are small, thin, crisp-skin fillets that want the same hot pan and a single turn. Ocean perch is the cheaper of the two and has the more dramatic skin; bream is finer in the flake and a little richer.

Common questions
Is ocean perch actually a perch?
No. It is a rockfish, genus Sebastes, from saltwater. Real perch are freshwater fish and not close relatives. The name describes the shape and the market, not the biology.
What does ocean perch taste like?
Mild and slightly sweet, closer to snapper or bream than to cod. The flakes are small and fine rather than big and loose, and the flavour is clean enough to carry a bold rub or a sharp sauce without disappearing under it.
Atlantic or Pacific ocean perch — is there a difference?
Two different fish under one name. The Atlantic one is Sebastes norvegicus, mostly landed by Iceland; Pacific ocean perch is Sebastes alutus, from the North Pacific. Both are rockfish, and a recipe written for one works for the other.
How do you get the skin crisp?
Dry the skin properly, salt it, and put it into a hot pan skin-down with a little oil. Press it flat for the first few seconds so it does not curl, then leave it alone. Do not turn it until the flesh has gone opaque nearly to the top.
