Norton Sound Red King Crab Stock Assessment for the fishing year 2012/13
1. Catches. This stock supports three main fisheries: summer commercial, winter commercial, and winter subsistence fisheries. Of those, the summer commercial fishery accounts for more than 90 % of total harvest. The summer commercial fishery retained catch reached a peak in the late 1970s at a littl...

The summer commercial fishery retained catch reached a peak in the late 1970s at a little over 2.9 million pounds. Since 1982, retained catches have been below 0.5 million pounds, averaging 275,000 pounds, including several low years in the 1990s.

Mature male biomass (MMB) is estimated to be on an upward trend following a recent low in 1997, and an historic low in 1982 following a crash from the peak in 1977. Uncertainty in biomass is driven in part by infrequent trawl surveys (every 3 to 5 years) and limited area of the winter pot survey. 3. Recruitment.
