The changes, which were finalized at the group's December meeting and go into effect Feb. 1, 2018, include reducing the commercial bag limits for cobia in Gulf state waters. The commercial limit, currently two per person, will drop to one per person, the same as the recreational limit. Also being reduced is the recreational and commercial vessel limit for cobia, from six to two per day in Gulf state waters. The third major change is the creation of a Gulf/Atlantic management boundary, which defines all waters north of the Monroe-Collier county line as Gulf state waters.
