Scientists at the University of Southampton have found a way to pry into the private lives of fish – by looking in their ears!
By studying ear stones in fish, which act as tiny data recorders, scientists can now reveal migration patterns and even provide insights into their sex life.
Managing fish stocks in a sustainable way is a major challenge facing scientists, conservationists, policy makers and fishermen. To get the best results, accurate information about the movements of fish in the wild is needed but gathering this information is extremely difficult. Continue reading
