THE CURRENT STATUS OF THE FISHERIES FOR CHIONOECETES SPP. (DECAPODA,OREGONIIDAE) IN ALASKAN WATERS

摘要

An overview of commercial fisheries for Chionoecetes crabs in Alaskan waters is provided, including stock assessment, harvest strategies, and trends in harvest and population size. Although a sum of peak harvests for individual Chionoecetes fisheries total more than 200 000 metric tons (t), the harvest from these fisheries during the 2008/09 season was less than 30 000t. Most Alaskan Chionoecetes fisheries have stock assessment surveys that provide high quality data, although the data for some stocks is available for only short time periods. There is a need for improvements to habitat mapping and estimation of stock assessment model parameters, as well as a review of the effectiveness of proxy thresholds.
