The SLED (Sea Lion Exclusion Device) is designed to reduce the number of marine mammals such as seals and sea lions that are trapped in the trawl nets of squid-fishing boats. The device allows sea lions to escape through the top hatch, while squid pass through a metal grid and get caught at the end of the net.
