About 3,500 dolphins have died this year in the waters of the Atlantic, a veritable massacre that is expected to increase over time. In just four weeks, 800 dolphins have run aground on the coast of the Bay of Biscay, which is 30 times larger than what is considered the “normal” level of beached in these animals, making this area one of the most Affected.
The problem is serious, as the Atlantic coast had not experienced a similar event since 1997. The bodies of dead dolphins on the coasts have been appearing since the beginning of this year, but especially in recent months there has been a record number of dolphin corpses Common in beaches like the Landes, Gironde, Charente and Vendée in France.
Scientists are extremely concerned about this fact and have not stopped studying mammals since the beginning of events. They consider that only the annual loss of one percent of cetaceans constitutes a threat to the permanence of the species . In addition, they warn of the enormous inconvenience of not knowing the effect that the decline of dolphin populations will have on marine ecosystems.
The main cause of all these deaths is attributed to the fishing methods used so far that particularly threaten these cetaceans. This is trawling , a type of industrial fishing consisting of huge nets, often with an opening similar in size to two football fields, which are dragged by two or more boats at both ends dragging all kinds of animals It finds its way.
Trawling is mainly used for catching seabass, mackerel, mackerel, hake and bonito, and is extremely dangerous for dolphins, who seek out fish banks to feed themselves, end up entering fishing grounds, inevitably being trapped between the Networks .
Fishing vessels, British, French, Irish, Dutch, Danish and Spanish who use these fishing practices are among the main responsible for the problem. All of them perform their fishing tasks in the English Channel, the Bay of Biscay and the Celtic Sea key points for cetaceans.
Industrial fishing is not a sustainable way of working, so many environmental groups such as Greenpeace or WWF claim fishing methods if they are. However, the main problem is that this requires considerable research and funding of the project, which in this way will promote the development and dissemination of more selective and sustainable fishing practices . In addition, scientists still find it very difficult to work in collaboration with the fishing industry.
Also contributing to this genuine cetacean massacre, affected by practices and increased maritime and fishing traffic, are chemical, plastic and noise pollution from seas and oceans. This calls for a level of action that will remove these threats and protect marine biodiversity.
