The Shark Conservation Act of 2009 (SCA) (H.R. 81, S. 850) was passed by the 111th United States Congress that amended the High Seas Driftnet Fishing Moratorium Protection Act and the Magnuson–Stevens Fishery Conservation and Management Act to improve the conservation of sharks. The bill was approved by the House of Representatives on March 2, 2009 by voice vote. It was taken up by the Senate and amended to incorporate further changes to Magnuson-Stevens, known as the International Fisheries Agreement Clarification Act. The Senate passed the amended bill as the Shark Conservation Act of 2010 on December 20, 2010 by unanimous consent, and the next day the House accepted the amendment, again by voice vote. The bill was signed into law by President Barack Obama on January 4, 2011.
