A new study led by scientists at the University of Miami (UM) Abess Center for Ecosystem Science and Policy and the Rosenstiel School of Marine and Atmospheric Science investigated how several species of coastal sharks respond to stress from catch-and-release fishing. The results revealed that each of the shark species responded differently. Hammerhead sharks were by far the most vulnerable to fighting on a fishing line.
Adds study co-author Dr. Neil Hammerschlag, a Research Assistant Professor at UM, "Many shark populations globally are declining due to overfishing. Shark anglers are some of the biggest advocates for shark conservation. Most have been making the switch from catch and kill to all catch and release. Our study helps concerned fisherman make informed decisions on which sharks make good candidates for catch and release fishing, and which do not, such as hammerheads."
The study, titled "Physiological stress response, reflex impairment and survival of five sympatric shark species following experimental capture and release," was published in the special theme issue "Tracking fitness in marine vertebrates "in the journal Marine Ecology Progress. The paper's co-authors are Austin J. Gallagher, Neil Hammerschlag, Joseph E. Serafy of the National Marine Fisheries Service in Miami and Steven J. Cooke of the Ottawa-Carleton Institute of Biology and Institute of Environmental Science in Ontario, Canada.
