CORRECTION: The first edition of this report, published in September 2018, had an incorrect value for North Atlantic right whale Potential Biological Removal (PBR). The PBR was reported as 1.4, but should have been reported as 0.9. In addition, a typographical error referencing the wrong stock name on page 149 in the Central Florida Coastal stock of bottlenose dolphins report was corrected.
