The Pisces Bycatch Reduction Shield was designed by Dan Watson as a development to his 2011 MA Product Design (University of Glasgow) project entitled the 'Escape Ring' which won the Design Innovation in Plastics Award run by the Worshipful Company of Horners. The rings were made of nylon with polyurethane illuminated LED lenses, and were inserted into a fishing net to hold the mesh open for juvenile and undersized fish to escape, acting in a similar way to an emergency exit sign. The concept of light influencing fish behaviour was taken forward over the next three years to create an underwater light that would illuminate the fishing net. By selecting a specific colour of light it is possible to attract or repel different species of fish, preventing unwanted bycatch. Intended to be used as a kit of ten lights, the Pisces can emit six different colours, be easily retro-fitted onto existing fishing gear, charges wirelessly and automatically switches on when underwater.
