About the Species

Sablefish. Credit: Rick Starr/CBNMS
U.S. wild-caught sablefish is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.

Population
Alaska and Pacific Coast sablefish are above target population levels.

Fishing Rate
At recommended levels.

Habitat Impacts
The trawl, longline, and pot gear used to harvest sablefish have minimal or temporary effects on habitat.

Bycatch
Regulations limit the amount of incidentally caught and discarded fish in the Alaska fishery. The catch shares program on the West Coast creates incentives to reduce bycatch.
Population Status
There are two stocks of sablefish: Eastern Bering Sea/Aleutian Islands/Gulf of Alaska and Pacific coast. According to the most recent stock assessments:
- The Eastern Bering Sea/Aleutian Islands/Gulf of Alaska stock is not overfished (2021 stock assessment) and not subject to overfishing based on 2021 catch data. Summary stock assessment information can be found on Stock SMART.
- The Pacific coast stock is not overfished (2021 stock assessment) and not subject to overfishing based on 2020 catch data. Summary stock assessment information can be found on Stock SMART.
Appearance
- Sablefish look much like cod. They are often referred to as black cod, even though they are not actually part of the cod family.
Biology
- Females can grow more than 3 feet in length.
- Females are able to reproduce at 6 ½ years old and more than 2 feet in length.
- Males are able to reproduce at age 5 and 1.9 feet in length.
- Sablefish spawn in deeper water along the continental slope from January to April in Alaska waters, and from January to March between California and British Columbia.
- Eggs develop in deep water for about 2 weeks until they hatch, then rise to the surface.
- Hatched larvae are moved by surface currents.
- Off southeast Alaska and British Columbia, juveniles appear in nearshore waters by fall.
- Juveniles have been found to migrate more than 2,000 miles in 6 or 7 years.
- Sablefish can live to be more than 90 years old.
Where They Live
Range
- Sablefish are found in the northeastern Pacific Ocean from northern Mexico to the Gulf of Alaska, westward to the Aleutian Islands and into the Bering Sea.
- There are two populations in the Pacific Ocean:
- Northern population inhabits Alaska and northern British Columbia waters.
- Southern population inhabits southern British Columbia, Washington, Oregon, and California waters.
- Both populations mix off southwest Vancouver Island and northwest Washington.
- They are most commonly found in Alaska waters.
Habitat
- Adults live on mud bottoms in waters deeper than 650 feet.
- Juveniles live throughout the water column in nearshore waters.
Fishery Management
- NOAA Fisheries and the North Pacific Fishery Management Council manage the sablefish fishery in Alaska.
- Managed under the Gulf of Alaska and Bering Sea/Aleutian Islands Groundfish Fishery Management Plans:
- Fishing season runs from approximately March 1 to November 15 (subject to change each year).
- Fixed gear (longlines and pots) harvests 90 percent of annual quota and trawl gear harvests about 10 percent.
- The majority of fixed gear is managed with an individual fishing quota (catch shares) program.
- The State of Alaska manages fisheries in state waters under a shared quota system and also manages separate state fisheries.
- NOAA Fisheries and the Pacific Fishery Management Council manage the sablefish fishery on the West Coast.
- Managed under the Pacific Coast Groundfish Fishery Management Plan:
- Coast-wide catch limits among different fishing groups and gear types.
- Daily trip limits for some vessels.
- Individual fishing quota (catch shares) for the trawl fishery and some of the fixed gear fishery. The West Coast groundfish trawl fishery is managed under a trawl rationalization catch share program.
- Full observer coverage in the trawl fishery, partial coverage in the fixed gear fishery.
Harvest
- Commercial fishery:
- In 2021, commercial landings of sablefish totaled 52 million pounds and were valued at $112 million, according to the NOAA Fisheries commercial fishing landings database.
- Sablefish are the highest valued finfish per pound in Alaska and West Coast commercial fisheries because of their rich oil content.
- Gear, habitat impacts, and bycatch:
- Longlines are used to harvest the majority of sablefish in Alaska.
- Increased catch efficiency, because of individual fishing quotas, reduces the number of hooks deployed and effects on bottom habitat.
- Individual fishing quotas reduce bycatch by allowing fishermen to operate at a slower pace and providing incentives to fish efficiently.
- Pot fishing has increased in the Bering Sea and Aleutian Islands, and the Gulf of Alaska, in response to killer whale interactions with fishing.
- West Coast fishermen harvest sablefish with trawls, longlines, and pots.
- Recreational fishery:
- Sablefish are occasionally caught in Alaska recreational fisheries during their summer migrations onto the continental shelf.
Scientific Classification
- Sablefish are found in the northeastern Pacific Ocean from northern Mexico to the Gulf of Alaska, westward to the Aleutian Islands and into the Bering Sea.

Taste
Sablefish have high oil content, making them exceptionally flavorful. They are often called butterfish because of their melt-in-your-mouth, oil-rich meat. Sablefish has a short shelf life and must be handled carefully.

Texture
Sablefish have soft, velvety texture. Their meat has large, white flakes.

Health Benefits
Very high in long-chain omega-3 fatty acids, EPA, and DHA.
