NMFS announces that the spiny dogfish commercial quota available to the coastal states from Maine through Florida for the 2010 fishing year (FY), May 1, 2010-April 30, 2011, has been harvested. Therefore, effective 0001 hours, April 1, 2011, federally permitted spiny dogfish vessels may not fish for, possess, transfer, or land spiny dogfish until May 1, 2011, when the quota for FY 2011 becomes available. Regulations governing the spiny dogfish fishery require publication of this notification to advise the coastal states from Maine through Florida that the quota has been harvested and to advise vessel permit holders and dealer permit holders that no Federal commercial quota is available for landing spiny dogfish in these states. This action is necessary to prevent the fishery from exceeding its annual quota and to allow for effective management of this stock.
