A stock assessment survey well below the minimum threshold
has prompted closure of the Southeast Alaska commercial red king crab fishery
for 2013/2014, say biologists for the Alaska Department of Fish and Game.

The region’s golden king crab fishery, which is divided into
seven fishery management areas, has a regional guideline harvest level of
590,000 pounds for this season, down from the 625,000-pound guideline harvest
level for the last three-year period, he said. The regional GHL for golden king
crab can go up to 800,000 pounds.

Regionally, the biomass of mature male red king crab has
been declining since 2001, and is currently at its lowest level in 23 years,

Six of eight survey areas exhibited poor stock health in

The biomass estimates for legal and mature red king crab for
the Southeast region are 0.74 million pounds and 0.91 million pounds
respectively for the 2013/2014 season. This is virtually the same amount of
mature crab estimated in 2012.

These legal and mature biomass estimates have also been
adjusted to incorporate mark/recapture assessments for seven areas in total. Generally,
the regional biomass estimate did not increase or decrease significantly from
last season, with a less than 1 percent change in legal biomass region-wide,
and only a 6 percent decrease in mature biomass.
