The invention, named Safetynet, was invented by Dan Watson, a former student at Glasgow School of Art and helps guide juvenile fish inadvertently caught in the nets to safety.
The Safetynet features a series of brightly lit escape rings that are fitted to conventional trawler nets to prevent meshes closing completely – allowing the smaller fish to escape.
Moreover, the rings themselves are lit up by converting tidal power into kenetic energy. Providing, in effect, an emergency exit sign.
