How to make fishing nets less destructive
Fish have favourite colours and dolphins hate high pitched noises.\n \nIn an effort to save rapidly dwindling global fish stocks, scientists are trying to figure out how to attract the right fish into nets, and keep protected species away.\n \nOn the southern coast of England, we meet the man who\u2019s designed a hi-frequency gadget which warns dolphins to stay out of fishing nets.\n \nIn Denmark, scientists show us how LED lights are able to show fish you don\u2019t want the exit from the net.\n \nAnd in Oxford we hear from the researchers using satellite technology to help the Thai government stop criminals from plundering the oceans.\n \nPresenter: Myra Anubi\nReporter: Rumella Dasgupta\nImage: The dolphin pinger
