In late July, the attention of national news media turned briefly to a huge mako shark caught off the coast of New Jersey. The 12-foot-long, 926-pound shortfin mako outweighed the current state record by 70 pounds, but because the rod passed hands during the fight it will not be officially recognized as a new record.
The big shark broke a rod in the fight to bring it aboard the 44-foot charter boat Jenny Lee, captained by Dave Bender. It happened during an overnight charter, drifting in 1,500 feet of water 100-miles out of Manasquan Inlet near the famous Hudson Canyon.
Shortly after excitement began to fizzle over this great catch, information was released on a new tagging study that suggests shortfin mako sharks might be experiencing overfishing in the western North Atlantic. Researchers from Nova Southeastern University’s Guy Harvey Research Institute (GHRI), the University of Rhode Island and other colleagues followed 40 satellite-tagged sharks in real time and 12 of them, or 30 percent, were captured in fisheries.
This information suggests the fishing mortality rates of shortfin mako sharks might be considerably higher than previously estimated using catches reported by fishermen, according to the press release. And despite their small sample size, researchers questioned the reliability of traditional data collection methods and expressed a serious concern over whether the current level of fishery catches for shortfin makos in the North Atlantic are sustainable.
