Marine Connection welcomes the news that seven audio recording underwater dolphin detectors have been installed along the UK Cornish coastline in the hope that by learning more about where dolphins, whales and porpoises congregate, it can reduce the number killed by fishing nets.

The devices are attached to offshore buoys in locations recommended by local fishermen, one metre long they hang approx 33 ft below the ocean surface. Over 1,000 dolphins, porpoises and whales were washed up dead on Cornish beaches between 2005 and 2008, 70% of them bycatch. Harbour porpoises are the most common victims of bycatch in inshore waters.
