Blue King Crab (Paralithodes platypus)

Status: The two major populations of blue king crab in Alaska are in the Pribilof Islands and in St. Matthew Island areas. Since the early 1980s abundance of the Pribilof Island population has peaked during the early 1980s and the mid-1990s, but has been at a fairly low level ever since. This population is too low at present to support a directed commercial fishery. The St. Matthew Island population also experienced peaks in abundance during the early 1980s and mid-1990s, but is increasing at the present. Recent increases in this population have allowed for a directed commercial fishery in 2009 and again in 2010.

Trends: The Pribilof Island population is currently experiencing low abundance relative to peaks in abundance in the early 1980s and mid-1990s. The St. Matthew Island population is currently trending upwards after ten years of low abundance.

Threats: No known threats at this time although there is concern for the continued low abundance of Pribilof Island blue king crab, despite no directed commercial harvest since 1999.
