DolphinFree English long version

The aim of the DolphinFree project is to limit dolphin mortality caused by pelagic trawler and gillnet fishing in the Bay of Biscay. Based on bio-acoustic and cognitive knowledge of the dolphin, it aims to propose prototypes :
an acoustic beacon emitting an understandable and interpretable signal to alert them to the presence of the net and the associated risk of mortality,
an energy generator (recovered from the surrounding environment) to increase the autonomy of the device, which includes a passive listening module to identify the presence of dolphins in order to trigger the emission of the acoustic signal (limiting noise pollution in the environment).
