Alaska’s cold, nutrient-rich waters harbor some of the most prized crab species in the world. Whether you’re a seafood lover, a commercial fisherman, or just curious about Alaskan marine life, this guide covers the five most common crabs found in Alaska. Learn to identify each species, understand what makes them unique, and why they’re valuable both ecologically and economically.
1. Red King Crab (Paralithodes camtschaticus)
The Red King Crab is Alaska’s most famous and commercially valuable crab, known for its large size and sweet, tender meat. It can weigh up to 24 pounds and has a distinctive bright red shell when cooked. Found primarily in the Bering Sea and around the Aleutian Islands, Red King Crabs support one of Alaska’s most lucrative fisheries, but strict regulations keep the population sustainable.
2. Blue King Crab (Paralithodes platypus)
Blue King Crabs are less common than their red counterparts and are mostly found in the colder waters around the Pribilof Islands and St. Matthew Island. They are smaller and have a bluish shell that turns purple-red when cooked. This species has a more limited commercial fishery due to lower population numbers and slower growth rates, making it a rarer delicacy.
3. Tanner Crab (Chionoecetes bairdi)
Also known as the Bairdi crab, the Tanner Crab is a mid-sized species with a reddish-brown shell and long, slender legs. It inhabits the continental shelf from the Gulf of Alaska to the Bering Sea. Tanner Crabs are prized for their sweet, delicate meat and are a staple in Alaskan crab fisheries, especially popular for soft-shell crab harvesting.
4. Snow Crab (Chionoecetes opilio)
Snow Crabs are widespread in Alaska’s northern waters, recognized by their long legs and pale, creamy white shells with a slight orange tint. They mature faster than King Crabs and have a sweeter, firmer meat texture. Snow Crabs are a cornerstone of the Alaskan crab industry, valued for their consistency and abundance across multiple fishing zones.
5. Dungeness Crab (Metacarcinus magister)
Dungeness Crabs are primarily found in the southeastern waters of Alaska, including the Inside Passage. They have a broad, hard, reddish-brown shell and are known for their sweet, nutty flavor. Though more common along the Pacific Northwest coast, Dungeness crabs contribute to Alaska’s diverse crab fishery and are popular in local markets and restaurants.
How to Choose
When selecting crab in Alaska, consider your intended use—whether for fresh eating, cooking style, or commercial purposes. Red and Blue King Crabs offer large, succulent meat perfect for steaming and special occasions, but Blue Kings are rarer and often pricier. Snow and Tanner Crabs provide more affordable options with sweet meat suitable for crab legs or soft-shell preparations. Dungeness Crabs are the go-to for those seeking a milder, nutty flavor and are ideal in recipes requiring whole crabs or crab cakes. Also, pay attention to the season and local regulations, as sustainable harvesting ensures continued availability. Freshness and size are practical factors: larger crabs generally yield more meat, but younger, smaller crabs may be more tender.
Frequently Asked Questions
Q: When is the best time to catch Alaskan crabs?
Most commercial crab seasons run from late fall to early spring, varying by species and region. For example, Red King Crab season typically opens in October and closes by January to protect spawning stocks.
Q: How do you identify a male versus a female crab?
Male crabs have a narrow, pointed apron on their underside, while females have a broader, rounded apron. Only male crabs are legally harvested in most Alaskan fisheries to protect breeding females.
Q: Are all Alaskan crabs safe to eat?
Yes, but it’s essential to buy from reputable sources and ensure the crab has been properly cooked and handled. Avoid consuming raw crab meat due to potential bacterial contamination.
Q: What is the difference between King and Snow crabs?
King crabs are larger with thicker legs and a richer flavor, while Snow crabs are smaller, with longer legs and a sweeter, more delicate taste. Both are popular but serve different culinary preferences.
Q: Can you eat the crab’s shell?
No, crab shells are hard and not edible. However, shells are often used to make flavorful broths or crab stock.
Q: How long can cooked crab be stored?
Cooked crab meat should be refrigerated and consumed within 3-5 days. For longer storage, freezing is recommended, but texture may be affected.
