In response to recommendations by the Atlantic States Marine Fisheries Commission, this rulemaking action proposes to cap and reduce individual and aggregate trap caps in the Offshore Area 3 lobster fishery and cap the number of permits a permit holder may have in nearshore Area 2. It also proposes to implement components of the Commission's Addendum XXVI to the American Lobster Management Plan. Among other things, the Addendum requires the lobster harvesting states to implement a trip-level reporting requirement with expanded data elements for all lobster fishermen in their respective jurisdictions, and recommends complementary action for Federal lobster permit holders. We propose to implement the mandatory trip-level harvester reporting requirement through this action. Finally, this action also proposes to make some minor administrative changes to the lobster trap transfer program, consider allowing the use of a substitute vessel to tend lobster gear in certain circumstances, and will remove some outdated text from the Federal lobster regulation at 50 CFR 697.
