Alaska’s icy waters harbor some of the world’s most sought-after crab species, contributing 29 percent of the world’s supply of crab. From the legendary Alaska king crabs to the abundant snow crab populations, these crustaceans support both commercial fisheries and coastal communities throughout the Last Frontier. With 18 species of crab inhabiting Alaskan waters, understanding each variety helps seafood enthusiasts, kayakers exploring coastal areas, and industry professionals navigate this diverse marine ecosystem.
The Big Picture: Alaska’s Commercial Crab Species
Ten species of crabs are caught in Alaskan crab fisheries, and seven of these have commercial importance. The commercially harvested species include:
- Red king crab (Paralithodes camtschaticus)
- Blue king crab (P. platypus)
- Golden king crab (Lithodes aequispinus)
- Tanner crab (Chionoecetes bairdi)
- Snow crab (C. opilio)
- Hair crab (Erimacrus isenbeckii)
- Dungeness crab (Cancer magister)
Three additional minor species are typically caught as incidental catch: scarlet king crab (L. couesi), grooved Tanner crab (C. tanneri), and Triangle Tanner crab (C. angulatus).
King Crab: Alaska’s Crown Jewel
Red King Crab – The Titan of Alaska Waters
The red king crab is the largest species of king crab. Red king crabs can reach a carapace width up to 28 cm (11 in), a leg span of 1.8 m (5.9 ft), and a weight of 12.7 kg (28 lb). Despite their impressive size potential, today, red king crabs infrequently surpass 17 cm (7 in) in carapace width and the average male landed in the Bering Sea weighs 2.9 kg (6.4 lb).
These magnificent crustaceans inhabit various regions across Alaska:
- Bristol Bay (primary fishing center)
- Norton Sound
- Pribilof Islands
- Kodiak Island
- Southeast Alaska
Red king crabs earned their name from the color it turns when it is cooked rather than the color of a living animal, which tends to be more burgundy. They’re harvested primarily from October through January, with only male crabs of a certain size being taken to ensure sustainable populations.
Blue King Crab – The Cold Water Giant
Blue king crabs are found as discrete small populations around St. Matthew Island, the Pribilof Islands, St. Lawrence Island, Nunivak Island, and in isolated cold water areas in the Gulf of Alaska. Known for their impressive size, these crabs prefer colder waters than their red cousins and are sometimes exceeding 18 pounds in weight.
Blue king crabs are particularly prized for their sweet meat and proportionally large claws. The limited distribution and careful management of these populations make them a special catch for commercial fishermen.
Golden King Crab – The Deep Sea Dweller
Golden (brown) king crabs primarily inhabit waters along continental slopes of the Aleutian Islands, Bering Sea, and Gulf of Alaska at depths greater than 180 m. These crabs are the smallest of the three main king crab species, typically weighing 5-8 pounds.
What makes golden king crabs unique:
- They live in deeper waters than other king crabs
- Have the mildest, sweetest flavor among Alaska king crabs
- Feature golden-orange shells
- Are becoming available fresh rather than just frozen
Scarlet King Crab – The Mysterious Deep Dweller
Scarlet king crabs are a deepwater species living in waters deeper than 600m. Though not commercially targeted, they’re occasionally caught as bycatch in golden king crab fisheries. These rare crabs are known for their extremely sweet meat and brilliant coloration.
Types of Alaskan King Crab: Understanding the Differences
When comparing types of alaskan king crab, each species offers unique characteristics:
Size Comparison:
- Blue king crab: Largest overall size
- Red king crab: Most abundant, medium-large size
- Golden king crab: Smallest of the three main species
Habitat Preferences:
- Red king crab: Shallow to moderate depths (up to 180m)
- Blue king crab: Cold, isolated areas
- Golden king crab: Deep continental slopes (180m+)
- Scarlet king crab: Extreme depths (600m+)
Flavor Profiles:
- Red king crab: Rich, sweet, distinctive flavor
- Blue king crab: Sweet with large, meaty claws
- Golden king crab: Mildest, sweetest taste
- Scarlet king crab: Extremely sweet (rarely available)
Snow and Tanner Crabs: The Versatile Alternatives
Snow Crab (Opilio) – Making a Comeback
After a devastating population collapse, the Bering Sea snow crab fishery reopened in mid-October 2024, marking the first harvest in nearly three years. Opilio, which are sometimes referred to as Opies or Queen crab, are the smaller, more readily available of the two species and typically weigh 1 ½-2 lbs.
Snow crabs are characterized by:
- Sweet, delicate white meat
- Long, easy-to-crack legs
- Smaller size compared to king crabs
- Year-round availability (when fishery is open)
Tanner Crab (Bairdi) – The Premium Snow Crab
Bairdi, also known as Tanner crab, can range in size from 3-5 lbs and command a higher price due to their size and restricted quotas. Many experienced crabbers consider Bairdi the best Alaska crab for its perfect combination of meat fill, sweet flavor, and thin shells that crack easily.
Key differences between snow crab varieties:
- Opilio: Smaller (1-2 lbs), more abundant
- Bairdi: Larger (3-5 lbs), sweeter meat, limited availability
Dungeness Crab vs Alaskan King: A Detailed Comparison
When considering dungeness crab vs alaskan king, these species serve different market niches:
Dungeness Crab:
- Size: Bodies up to 7-inches in width, smaller than other crabs in Alaska
- Habitat: Shallow bays and estuaries
- Weight: Approximately 2 pounds average
- Meat: Salty-sweet flavor, delicate texture
- Harvest: May through December (varies by location)
King Crab Advantages:
- Significantly larger size (up to 24 pounds)
- Meatier legs with more yield per crab
- Richer, more buttery flavor
- Higher market value
- Considered more prestigious
Dungeness Crab Advantages:
- More accessible for recreational crabbers
- Available in shallower waters near shore
- Longer harvest season
- Lower price point
- Excellent for kayak fishing expeditions
Crabs in Alaska Today: 2026 Fishery Status
The landscape of crabs in alaska today reflects both challenges and cautious optimism:
Current Fishery Updates (July 2026)
Snow Crab Recovery: Earlier this month, commercial snow crabs started hitting Unalaska’s docks again for the first time in nearly three years. The 2024-2025 season opened with a conservative harvest limit of 4.72 million pounds, the smallest in the fishery’s history.
Red King Crab Outlook: Bristol Bay red king crab fishery opened for the 2024-2025 season, though recruitment, a key to the stock’s future, has remained frustratingly low over the last decade. Scientists urge continued conservative management.
Golden King Crab Trends: A handful of crab boats continue to drop pots for 4.88 million pounds of golden king crab at the far-flung Aleutian Islands region in a fishery that ends in March.
Regional Developments:
- Southeast Alaska: New regulations allow smaller commercial harvests when stocks fall below traditional thresholds
- Bering Sea: Tanner crab fishery targeting 6.27 million pounds
- Market prices: Significant increases due to tightened supplies
