May 18, 2016 — The dangers for the world’s seas and oceans are many — from climate change and warming waters to overfishing related to the needs of growing world populations. As a major 2015 paper in the journal Science noted, extinction of many species is a looming reality, given the current decline in quality of aquatic ecosystems. The perils for large marine mammals, sharks and other large fish are well known to the public. But there are many other dangers. For example, the rapid rate of ocean acidification, which appears to be unprecedented in Earth’s history, threatens to decimate shellfish populations.
Of course, debates about overfishing and sustainable management practices rage in virtually every fishery across the world. These policy debates are seldom simple to resolve and involve complex tradeoffs: Traditional fishing rights versus government regulation; short-term profits versus longer-term sustainable growth; local population food needs versus larger ecological and stewardship concerns. Organizations such as the U.S. National Oceanic and Atmospheric Administration (NOAA) and the Food and Agriculture Organization (FAO) of the United Nations keep statistics on the state of fisheries and their relative health. The FAO’s annual The State of World Fisheries and Aquaculture provides a comprehensive overview. For U.S. reporters and editors covering these issues on the nation’s coasts, it is worth getting to know some of the long and complex policy and regulatory history in this area, which for nearly four decades has been governed by the Magnuson-Stevens Fishery Conservation and Management Act.
