King Crab 101 - Alaska King Crab Facts
The Different Types
I put together this page because I have perceived a great deal of confusion surrounding the different types of king crab - all three. Before I started crab fishing, I was not aware that there was any difference. Whether you are a buyer for a restaurant or just an individual crab enthusiast - I hope that this page sheds some light on an this subject.
There are three species of king crab in Alaska- red king crab, blue king crab, and brown king crab. They are found in different areas of Alaskan waters. Below is a detailed map of the main habitat areas. Most of the king crab harvested in Alaska comes from the Bering Sea. There are smaller fisheries to the north in Norton Sound and in the southeast.
Red King Crab
Caught in the waters of Bristol Bay and Norton Sound, the true red king crab is the most prized species of crab in the world, with strong demand from consumers in Japan, the US, and Europe. Alaska's largest harvest of red king crab takes place in the waters of Bristol Bay. Roughly 100 boats participate in the fishery and harvest millions of pounds over a period of 2 to 3 months. Alive, red king crab are actually a dark burgundy in color. When they are cooked they turn bright red- with scarlet-red highlights on the top part of the shell, and especially around the toes. Taste-wise, true red king crab is the best in the world. The meat is snow-white, with highlights of bright red. During the season, a growing number of white table cloth restaurants offer fresh red king crab- a sumptuous treat. Succulent, and served steaming-hot, there is no other meal I would rather have!
Blue King Crab
Caught in Alaska near St. Matthew Island and the Pribilof Islands, this species is known for its sweet meat and proportionally giant claws. Pribilof Island blue king crab are among the largest crab in the world. In Dutch Harbor in 1998 I saw blue king crab being unloaded at the dock weighing more than 18 lbs! When they are alive, blue king crab are brown with royal blue highlights. However, when they are cooked they turn a bright orange-red. This is why blue king crab is generally marketed in the United States as "red king crab". Taste-wise, blue king crab is similar to red king crab, typically sweeter, although slightly milder in flavor than red. When it is available in-season, I like serving blue king crab when I am entertaining guests. They are always amazed at the size of the claws.
Golden King Crab
Caught in the waters around the Aleutian chain islands, golden king crab are the smallest of the three main species. Their shells are golden-orange in color. They have the mildest flavor of the Alaska's three commercially-harvested types of king crab. Golden king crab generally have the lowest percentage of meat "infill" inside the shells, and sell for less than blue or red. Because they are one of the most abundant types of crab in Alaska, they are beginning to become available fresh as opposed to brine frozen. A growing number of chefs around the United States are beginning to request and serve fresh-cooked Alaska golden king crab legs.
Scarlet King Crab
Though not commercially marketed, the Bering Sea also holds a fourth type of king crab known as the Scarlet king crab. Though I have never tried this type of king crab, I have heard a tale or two that they have extremely sweet meat. Scarlet king crab have neither the size nor population to sustain a commercial harvest.
