Since the beginning of the year alone, a record number of up to 600 dolphins have washed up on France’s Atlantic coast. So what’s going on?

What’s the story?

Since the start of 2019, up to 600 dolphins have washed up on beaches along France’s Atlantic coast.

According to two different surveys, the numbers of carcasses found this year is between 400 and 600 – but even the lower estimate is higher than any previous year at the same period.

While dead dolphins wash up on beaches in France each year scientists say the situation is alarming.

“If you compare these figures to last year’s over the same period, there are already more dead dolphins that the previous years, which were already record years,” said researcher Hélène Peltier from the Pelagis marine life observatory which carries out surveys.

“Will things calm down? That is the question now, we’ll need to look at the numbers at the start of spring to make an accurate assessment of the situation,” she said.

The dolphins washed up on the stretch of Atlantic coast running all the way from southern Brittany to the Spanish border with large numbers of carcasses found in the departments of Vendée and in the Charentes Maritimes.

Scientists say these numbers are only the tip of the iceberg as many when dolphins die, many just sink to the bottom of the ocean or are washed out to sea rather than ending up on the beaches.

These deaths could also threaten the dolphin populations in the years to come, researchers say.

Why is this happening?

Although hundreds of dead dolphins wash up on French beaches every year, this is a record number so early on in the year.

Most of the dead dolphins found bear injury marks which researchers say are caused by big fishing boats and the large fishing nets they use.

“Among the carcasses found, 93 percent show signs that they have been captured by fishing vessels and their equipment such as mutilations, amputations and fractured jaws,” according to the French environmental charity France Nature Environnement (FNE).

The dolphins get caught in the vast nets used to catch fish like hake and sea bass, which the dolphins like to eat. Some of these nets are fixed in the sea bed and when dolphins get stuck in them, they can’t come up for air to breathe and they suffocate.

Trawlers are also a problem as they drag large fishing nets behind them which dolphins also get caught in and suffer injuries and die. When they get stuck, dolphins panic, and the stress can also kill them.

Is there a solution?

An obvious solution would be to reduce the number of large fishing vessels.

Environmental organisations want the number of big trawlers and other large fishing boats – which belong mainly to France and Spanish fleets – allowed to fish in those waters to be cut immediately. They are calling for a better coordination between the French and Spanish governments to find a solution to the problem.

They also want observers to be allowed to board these vessels to control the fishing practices, but in practice, they say this isn’t happening as the boats are reticent to do so.

Other solutions include putting acoustic ‘repellents’ on boats to keep the dolphins away. These are called ‘pingers’ and this year, for the first time all French pelagic trawlers were equipped with some.

But given the record numbers of dolphin deaths this year already, the pingers seem to have little effect.

FNE has pointed out that one of the problems could be that the pingers are not attached to the large nets on the sea beds, where many dolphins get caught.
Comment: UPDATE 30th March

The number of dead and mutilated dolphins has risen by 500 in just over a month and the cause for this spike remains a mystery to investigators, RT reports that:
A record-breaking 1,100 dead dolphins have been discovered with their fins cut off along France’s Atlantic coast since the beginning of the year, sparking alarm among animal protection groups.

Just three months into 2019, the astonishing number of mutilated dolphins is already greater than last year’s record, which was the highest for decades. Furthermore, autopsies carried out on this year’s discoveries found they’d undergone an extreme level of mutilation.

The mass deaths are generally a result of aggressive industrial fishing, with 90 percent of the mortalities believed to have been caused by accidental capture. Animal welfare groups say fisherman will often cut body parts off the trapped dolphins to save their nets.

However, this year’s spike in fatalities is a mystery and France’s Ecology Minister Francois de Rugy has launched a national plan to protect the animals. He has ordered an investigation into the use of acoustic dolphin deterrent devices by trawlers in the Bay of Biscay, an industrial fishing hub in the Atlantic Ocean.

Animal rights group Sea Shepherd have lambasted Rugy’s efforts as “useless,”claiming many trawlers that they observe don’t activate the repellent device for fear of scaring off other valuable fish like hake and sea bass, and say more is needed to protect.
