648.107 Conservation equivalent measures for the summer flounder party/charter and recreational fishery.
top (a) The Regional Administrator has determined that the recreational fishing measures proposed to be implemented by Massachusetts through North Carolina for 2011 are the conservation equivalent of the recreational fishing season, minimum fish size, and possession limit prescribed in §§648.104(b), 648.105, and 648.106(a), respectively. This determination is based on a recommendation from the Summer Flounder Board of the ASMFC.
(1) Federally permitted party and charter vessels subject to the recreational fishing measures of this part, and other recreational fishing vessels harvesting summer flounder in or from the EEZ and subject to the recreational fishing measures of this part, landing summer flounder in a state whose fishery management measures are determined by the Regional Administrator to be conservation equivalent shall not be subject to the more restrictive Federal measures, pursuant to the provisions of §648.4(b). Those vessels shall be subject to the recreational fishing measures implemented by the state in which they land.
