Alaska is famed for its rich marine life, especially its diverse crab populations. This guide covers five common crab species found in Alaska’s cold waters, perfect for seafood lovers, fishers, and anyone curious about these fascinating crustaceans. Each species has unique traits and culinary value, making them worth knowing whether you’re planning a catch or a feast.
Red King Crab (Paralithodes camtschaticus)
Red King Crab is arguably the most iconic and commercially valuable crab species in Alaska. Known for its large size—legs can span up to 6 feet—the Red King Crab boasts sweet, tender meat prized in fine dining. It inhabits deep, cold waters and is mainly harvested in the Bering Sea. Its high market demand has led to regulated fishing seasons to maintain sustainability.
Blue King Crab (Paralithodes platypus)
Blue King Crabs are less abundant than Red Kings but still significant in Alaska’s crab fisheries. They are typically smaller, with a bluish shell that turns reddish when cooked. Blue Kings prefer colder, shallower waters near the Pribilof and St. Matthew Islands. Their meat is firm and flavorful, making them a sought-after delicacy despite a more limited fishery.
Snow Crab (Chionoecetes opilio)
Snow Crabs, also called opilio crabs, have a thinner shell and longer legs compared to king crabs. They are widespread in Alaska’s northern waters and are especially abundant in the Bering Sea. Snow Crab meat is sweet and delicate, often used in crab legs and crab cakes. The species supports one of Alaska’s largest crab fisheries, with strict quotas to prevent overharvesting.
Tanner Crab (Chionoecetes bairdi)
Tanner Crabs are closely related to Snow Crabs but tend to have a rougher shell and a more oval shape. Found primarily in the Gulf of Alaska and the Bering Sea, they are smaller and less commercially valuable but still popular among local fishers. Their meat is sweet and flaky, commonly harvested for both commercial and sport fishing.
Dungeness Crab (Metacarcinus magister)
Dungeness Crabs are more commonly associated with the Pacific Northwest but also inhabit southern Alaska coastal waters. They have a reddish-brown shell and are prized for their tender, sweet meat. Although not as abundant in Alaska as king or snow crabs, Dungeness crabs are a staple for coastal communities and recreational crabbers due to their accessibility and taste.
How to Choose
Choosing between these crab species depends on your priorities: size, flavor, availability, and price. Red King Crabs offer the largest size and luxurious meat but come at a premium cost due to their limited fishery. Snow and Tanner Crabs provide a balance of sweet flavor and more affordable pricing with abundant availability. Blue King Crabs are rarer and can be a specialty item, while Dungeness Crabs are ideal for those near southern coastal areas seeking a sweet, accessible option. Consider the crab’s intended use—whether for a special meal or regular consumption—and local availability when making your choice.
