Intensive fishing, as well as fish, seabird deaths. "A study published by the scientist andmarine biologist Ramunas Žydelis, widespread in our country from the Pu-BirdLifeItaly, reveals that around 400,000 birds die each year in trammel nets '", a very intensefishing technique used throughout the world. "
A number that exceeds even that relating to the killing of birds documented inlongline fisheries. Research provides, for the first time, a global estimate of theincidental catch of these specimens, and stresses that the large number of victims isan estimate "to fall", due to the lack of information and data.
"Unlike the longlines and bottom trawling, for which simple solutions exist already thetechniques available to reduce the incidental catch of seabirds - says Ramunas Žydelis- the search for similar measures for the trammel nets has been very limited to dateand further efforts to tackle the problem are urgent".
Trammel nets are fixed, very used in coastal fishing and nylon which makes theminvisible. Seabirds often remain entangled and drown while pursuing their preyunderwater.
Among the species accidentally caught are Humboldt penguins, species in danger ofextinction, the long-tailed Duck, the rare urietta mormoreggiata, and other specimensas the Guillemots. But birds are not the only victims of these methods: gillnets are aserious threat to dolphins, whales, seals and turtles.
