Dances with fish

New Zealand marine biologist Sunil Kadri, co-founder of Optoswim Technologies, is the O2 X Male Entrepreneur of The Year, awarded in London for technology Kadri created to improve the production of farmed salmon, dubbed the ‘fish disco’ or ‘fish gym’. Optoswim’s products use a special LED light to stimulate the fish into swimming, making them leaner, healthier and tastier. The business has been operating for nearly two years and its technology will soon be used in fish farms across the globe. Glasgow-based Kadri explains that “essentially it’s a system for providing exercise to fish in farms. This encourages the development of muscle over fat – leading to leaner, healthier and tastier fish.” Kadri discusses his “fish gym” in a podcast on British site SmallBizPod.
