Fish are being threatened by rising levels of man-made noise pollution.
So say scientists who have reviewed the impact on fish species around the world of noises made by oil and gas rigs, ships, boats and sonar.
Rather than live in a silent world, most fish hear well and sound plays an active part in their lives, they say.
Increasing noise levels may therefore severely affect the distribution of fish, and their ability to reproduce, communicate and avoid predators.
