Noise pollution impacts fish species differently

Acoustic disturbance has different effects on different species of fish, according to a new study from the Universities of Exeter and Bristol 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.” (more…)

Ship noise impairs feeding and heightens predation risk for crabs

A study published in the journal Animal Behaviour found that the noise of passing ships disrupts feeding for the common shore crab.

Perhaps worse, the team from the Universities of Exeter and Bristol also found that when threatened, crabs took longer to retreat to shelter and lost their natural ‘play dead’ behaviour.

In coastal seas around the world noise caused by humans is a dominant feature, with construction and transportation fundamentally modifying ocean soundscapes. 

Working with the same common shore crabs that children delight in catching on crablines in UK harbours, the team found ecologically-critical effects of ship noise-playback on behaviour.  (more…)
