Harbour porpoises needlessly dying in UK waters, says WWF

Charity calls for action as report finds more than 1,000 killed in fishing nets each year

More than 1,000 harbour porpoises are needlessly dying in UK waters each year, according to a report from a global environmental organisation.

The study by the World Wide Fund for Nature (WWF) says the small porpoises are accidentally trapped in fishermen's nets, causing them to suffocate and die.
