Fish might communicate in regional accents

The video explores the impact of human-generated noise on fish in the River Mersey. Scientists from Exeter University use underwater microphones to study how noise pollution affects fish communication, stress levels, and development. The study highlights the distinct regional accents of fish and the challenges they face in breeding due to noise and rising sea temperatures. Potential solutions include restricting boat activity around breeding grounds. The research is funded by the Natural Environment Research Council.
