This action corrects the SUPPLEMENTARY INFORMATION section to a final rule published in the Federal Register on April 20, 2010, which erroneously waived the 30 day delay in effective date. A 30-day delay in effectiveness will allow fishermen to come into compliance with the terms of the rule, as was originally intended, without compromising any other aspect of the fishery. NMFS will not enforce the requirement that owners be onboard vessels unless otherwise required by statute or regulation.
