Description:

Through 2010, octopuses were managed as part of the BSAI “other species” complex, along with sharks, skates, and sculpins. Historically, catches of the other species complex were well below TAC and retention of other species was small. Due to increasing market values, retention of some of the other species complex members increased. Beginning in 2011, the BSAI fisheries management plan was amended to provide separate management for sharks, skates, sculpins, and octopus and set separate catch limits for each species group. Catch limits for octopus for 2011 were set using Tier 6 methods based on the maximum historical incidental catch rate. In 2012, a new methodology based on consumption of octopus by Pacific cod was introduced; this method has been in use since 2012 and is recommended for 2017 and 2018. The consumption estimates have been updated this year with additional diet data for 2007-2015. The new estimates show an increase in consumption of octopus in recent years, due to both an increasing cod population and increases in the proportion of octopus in cod diets.
