Rockfish comes primarily from the Pacific Ocean, harvested along the western coast of North America from Alaska down through California. If you bought rockfish at a grocery store or ordered it at a restaurant in the United States, it almost certainly came from Pacific waters, where more than 50 species in the genus Sebastes are commercially fished. A single Atlantic species also exists, but it’s typically sold under different names.
Pacific Coast: The Heart of Rockfish Territory
The northeast Pacific Ocean is rockfish territory. The genus Sebastes includes over 50 species in Pacific waters, making it one of the most species-rich groups of fish along the West Coast. These fish range from the shallow rocky reefs of Southern California to the deep, cold waters off Alaska. Oregon and Washington account for the majority of commercial landings for popular species like yellowtail rockfish, which brought in 6.7 million pounds in 2023 alone, valued at $1.7 million.
Alaska is another major source. NOAA maintains a dedicated field guide just for Alaskan rockfish species because there are so many of them in those waters. California also has a long history of rockfish harvesting, particularly for species that live around nearshore reefs and kelp forests. If your fish label says “Pacific rockfish” or simply “rockfish,” it was pulled from somewhere along this coastline.
The Atlantic’s Lone Rockfish
The Atlantic Ocean has just one species in the rockfish family: Acadian redfish, also called ocean perch. It’s found from the coast of Norway across to Georges Bank off New England, most commonly in the deep waters of the Gulf of Maine at depths reaching 975 feet. In New England and Canada, this fish is sold as “redfish” or “ocean perch” rather than rockfish, so you’re unlikely to see Atlantic-caught fish labeled as rockfish at the store.
This creates a simple rule of thumb: if you’re buying something called rockfish in the U.S., it’s a Pacific fish. If you see ocean perch or redfish from the Atlantic, that’s the lone East Coast cousin.
Where Rockfish Live in the Ocean
Rockfish are bottom-dwellers and mid-water fish, depending on the species. Many live around rocky reefs, underwater boulders, and other hard structures on the ocean floor, which is where their common name comes from. Some species hover in schools above these structures, while others tuck themselves into crevices and stay close to the bottom.
Depth ranges vary enormously across species. Some nearshore rockfish live in relatively shallow water around kelp beds, while deep-water species like the Acadian redfish in the Atlantic inhabit waters nearly 1,000 feet deep. Pacific species span a similarly wide range, with some of the deepest-dwelling varieties found in Alaskan waters.
How Rockfish Are Caught
Commercial fishers use several methods to bring in rockfish along the West Coast. Bottom trawling is one of the most common, dragging a weighted net along the ocean floor to scoop up groundfish including rockfish. Midwater trawls target species that school higher in the water column, like yellowtail rockfish.
Hook-and-line methods are also widely used. Bottom longlines stretch along the seafloor with baited hooks at intervals, while vertical longlines (also called droplines) suspend a weighted line vertically from a surface buoy with hooks attached at various depths. Fishers in Washington, Oregon, and California also use pole-and-line setups, traps, and troll gear. Recreational anglers catch rockfish too, particularly from party boats off the California and Oregon coasts using similar vertical hook-and-line techniques.
What “Rockfish” Means at the Store
The FDA’s official acceptable market name for Sebastes species is simply “rockfish.” You may also see it labeled as “Pacific snapper” or “Pacific red snapper,” but those are vernacular names that can be misleading. The FDA notes that using names like “Pacific Red Snapper” for interstate commerce may constitute misbranding, since it can confuse consumers who associate “snapper” with the true red snapper found in the Gulf of Mexico, which is a completely different fish.
If you see rockfish at the counter, it’s worth asking which species it is. With more than 50 Pacific species, the flavor, texture, and price can vary. Popular market species include yelloweye, black rockfish, canary, and vermilion, each with slightly different characteristics. The fish is generally mild, lean, and white-fleshed regardless of species.
Why Rockfish Are Slow to Recover
One remarkable fact about rockfish is their extraordinary lifespan. Pacific rockfish species range from 11 years to over 200 years in maximum lifespan, making some of them among the longest-lived vertebrates on Earth. The rougheye rockfish, found in deep Alaskan waters, holds records well past the 200-year mark.
This extreme longevity comes with slow growth and late reproduction, which means overfished populations take decades to bounce back. Several West Coast rockfish species were declared overfished in the early 2000s, and strict catch limits have been in place since. Some populations have recovered enough for restrictions to ease, while others remain protected. This is why sustainable sourcing matters more for rockfish than for faster-reproducing species, and why your rockfish fillet represents a fish that may have been alive for decades before it reached your plate.
