The Magnuson-Stevens Act was first enacted in 1996 and was revised and re-authorized in 2007. It was established to promote responsible conservation and management of fishery resources. Because a decrease in pH has been shown to impact both the growth and physiology of fishes, understanding and mitigating the impacts of ocean acidification is critical to one of the purposes outlined in this act which is to foster and maintain the diversity of fisheries in the United States.
