Omega Protein Corporation is a publicly traded US company founded in 1913 as a fishing operation. As of 2015 it still operated a fishing fleet, and produced food ingredients, dietary supplements and animal feed. Their products included fish oil, fish meal, and proteins. In the 2000s it expanded via acquisitions into ingredients produced from milk and plants. Omega Proteins fishing fleet takes about 90% of the menhaden harvested in US waters; the extent of its harvest has been a subject of controversy. In December 2012, in the face of the depletion of Atlantic menhaden, the Atlantic States Marine Fisheries Commission imposed a limit on Omegas operations, "capping the total annual commercial catch at 170,800 metric tons, about 80 percent of the average harvest from the last three years." In 2008 and 2009 Omega Protein received certification from Friend of the Sea, an international non-profit, non-governmental organization dedicated to the conservation of marine resources. Omega Protein’s operations in both the Gulf and along the Atlantic have been regularly recertified since their first certification, with the Gulf of Mexico fishery most recently being recertified in the fall of 2014.
