Omega Protein – a reduction fishery company with operations in the northwest Atlantic and the Gulf of Mexico – takes 90% of the total menhaden harvest in the United States. In October 2005, the Atlantic States Marine Fisheries Commission (ASMFC) approved an addendum to Amendment 1 of the Interstate Fishery Management Plan for Atlantic Menhaden, which "established a five-year annual cap on reduction fishery landings in the Chesapeake Bay", imposing a limit on reduction fishery operations for 2006–2010. In November 2006, that cap was established at 109,020 metric tons; this cap remained in place until 2013.
