Do sharks survive after the hook?
Fitbit-like sensors are the best tools for monitoring whether sharks survive catch-and-release fishing — essential data for fisheries management — according to a peer-reviewed study published June 23 by scientists from Mote Marine Laboratory in Sarasota, Florida. The study, published online in the scientific journal Fisheries Research, is the first to show that motion-sensing accelerometer tags detect whether a shark has survived and how it recovers from capture stress with much greater certainty than other prevailing technologies. Usually scientists fit sharks with satellite or acoustic transmitters to infer whether a shark has survived using indirect signals like location or depth. In contrast, accelerometers measure sharks’ fine-scale movements directly and with high resolution, including every tail beat, body tilt, ascent and descent. Read the rest here 16:41
