Acceptable Biological Catch (ABC) Control Rule

Allowable Biological Catch (ABC) Control Rule

In December 2016, the Council directed staff to start work on a plan amendment that would modify the ABC Control Rule to address flexibility allowed under the MSA and revise how uncertainty and risk tolerance are addressed in setting ABCs.  The Amendment includes actions to: 1) revise how the SSC evaluates assessment uncertainty; 2) revise how the risk tolerance is specified; and 3) allow phase-in and carry-over of ABCs. An IPT was formed to develop actions and alternatives, and the SSC and Council have regularly reviewed progress and provided guidance during 2017 and 2018. Scoping was held in January 2019 and comments from those meetings were reviewed by the Council in March 2019.
