Sebastes norvegicus, commonly known as the golden redfish, Norwegian redfish, Atlantic ocean perch, Norway haddock or Uer, is a slow-growing, long-lived marine teleost fish in the family Sebastidae. It is native to the cold, deep waters of the North Atlantic, ranging from the coast of Norway and the Barents Sea across to Greenland, Iceland, and the Gulf of Maine. The genus name Sebastes is derived from the Greek sebastos, meaning "magnificent" or "venerable," while the species epithet norvegicus denotes its strong historical association with the Norwegian fishing industry. Historically, this species has been a cornerstone of Atlantic fisheries, valued for its striking coloration and firm, succulent flesh.

The fish is easily identified by its vibrant, brilliant orange-to-red coloration, which serves as camouflage in the deep-water environments where it resides. It features a robust, spiny-rayed body, large eyes adapted for low-light conditions, and a heavily armored head with sharp spines. Sebastes norvegicus is a deep-sea inhabitant, typically found at depths ranging from 100 to 1,000 meters, preferring rocky, uneven substrates. Uniquely, unlike most marine fish that spawn by releasing eggs into the water column, this species is viviparous; it gives birth to live, developed larvae. Because they grow very slowly and have a late age of maturity, their populations are highly sensitive to overfishing.

Golden Redfish is celebrated in Northern European and North American coastal gastronomy for its mild, sweet, and delicate flavor profile, often compared to cod but with a slightly firmer texture and higher oil content. The meat is exceptionally white, lean, and flaky, making it ideal for a wide variety of preparation methods. In Norway, it is known as uer and is traditionally pan-seared or baked with aromatic herbs, while in North American commercial markets, it is frequently served as a premium fried fish fillet or featured in refined soups and stews. Because it is caught in deep, cold waters, the quality of the flesh is consistently high, retaining moisture during various cooking processes.

Nutritionally, Sebastes norvegicus is an outstanding source of high-quality, complete protein and is particularly noted for its rich content of long-chain omega-3 polyunsaturated fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It is also an excellent source of essential micronutrients, including Vitamin B12, Vitamin D, selenium, and iodine, which are critical for metabolic and cognitive health. The fish’s lipid profile supports cardiovascular function by helping to maintain healthy cholesterol levels and reducing systemic inflammation. As with many deep-sea species, it is a dense source of high-value essential amino acids, including leucine, lysine, and arginine.
