Fish have regional accents, say scientists

And it's not even April Fool's Day...

Do fish really have regional accents?

Scientists say the sounds cod make to communicate differ from region to region – and may be vulnerable to noise pollution.

Cod often use sounds to attract mates and warn of nearby predators.

But if the sounds are disrupted by human marine activity it may affect cod's breeding by inhibiting integration and reproduction, scientists say.

But can you hear the difference between a north-eastern Atlantic cod and a north-western Atlantic cod?

Apparently researchers can.They say there are different regional dialects used by cod.

The sounds are emitted from the fish's swim bladder.

Scientists are concerned that human-made noise pollution in the sea is disrupting their communication and mating patterns as a result.

To maintain global fish stocks, this must be understood and reduced, say the researchers.
