Noise Pollution Impacts Different Fish Differently

Acoustic disturbance has different effects on different species of fish, according to a new study which tested fish anti-predator behaviour.  Three-spined sticklebacks responded sooner to a flying seagull predator model when exposed to additional noise, whereas no effects were observed in European minnows. Lead author Dr. Irene Voellmy of Bristol's School of Biological Sciences said, "Noise levels in many aquatic environments have increased substantially during the last few decades, often due to increased shipping traffic. Potential impacts of noise on aquatic ecosystems are therefore of growing concern." read more
