The Council reviewed a discussion paper to explore mechanisms to create a registry for motorized rental boats that are used by unguided anglers to harvest halibut in IPHC regulatory areas 2C and 3A, and initiated an analysis. The Council requested the discussion paper in December 2017, and stated that they were concerned that differences in harvest regulations between guided and unguided sport anglers, and the apparent growth of the rental boat segment of the unguided sector may negatively impact other halibut fishing sectors. The discussion paper provided an overview of existing vessel registration programs, examined patterns in halibut harvest in the unguided, guided, and commercial sectors in recent years, and addressed questions posed by the Council in their December 2017 motion. After review, the Council passed a motion initiating an analysis of alternatives to require registration for non-guided rental vessels in IPHC areas 2C and 3A, and align bag limits between charter anglers and anglers on non-guided rental vessels by applying the charter angler daily bag limit and size limit to recreational anglers.
