Dead dolphins are washing up on France’s Atlantic coast in such high numbers that local populations of the mammals are at risk, marine biologists say.
The overwhelming majority drowned in the nets of fishing trawlers. Post mortems often show fractures, broken tails and flippers and deep incisions cut into their skin by the nets. Some have been mutilated as fishermen release their bodies.
“We’re reaching mortality rates that threaten the survival of the dolphin population in the Bay of Gascony,” said Morgane Perri, a marine biologist in Brittany, western France.
“For the last three years, we’ve seen more than 1,000 deaths (of dolphins and porpoises) over a four-month period each winter.”
Common dolphins are the hardest hit. Scientists believe those found on beaches represent a small fraction of the total number dying in fishing nets off the coast of France. The real number is likely to be five to 10 times higher, they estimate.
