A new analysis of population trends among coastal sharks of the southeast U.S. shows that all but one of the seven species studied are increasing in abundance. The gains follow enactment of fishing regulations in the early 1990s after decades of declining shark numbers.
Now, says lead scientist Cassidy Peterson, a graduate student at William & Mary’s Virginia Institute of Marine Science, “We’ve shown that after over two decades of management measures, coastal shark populations are finally starting to recover and reclaim their position as top predators, or regulators of their ecosystem. Our research suggests we can begin to shift away from the era of ‘doom and gloom’ regarding shark status in the United States.”
Joining Peterson in the study, published in the latest issue of Fish and Fisheries, were VIMS professor Rob Latour, Carolyn Belcher of the Georgia Department of Natural Resources, Dana Bethea and William Driggers III of NOAA’s Southeast Fisheries Science Center, and Bryan Frazier of the South Carolina Department of Natural Resources.
