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.
The highest levels of incidental catch of seabirds have been found in the Baltic Sea,where it is estimated that 76 thousand birds die each year, and also in the North andNorthwest of the Pacific Ocean. In addition, there are still geographical areas for whichthere is no shortage of information, such as the South Atlantic Ocean, theMediterranean and Southeast Pacific, as well as waters of Japan and Korea. To date,the corrective actions have been very sporadic. However, there is a recognition of theproblem by the authorities.
The Plan of action of the Union European, launched last November to minimize thebycatch of seabirds with fishing nets, emphasized that the problem of the trammelnets is a priority. However, the implementation of this plan is currently voluntary. Forthis reason, BirdLife International calls for compulsory measures to be included in theframework of the common fisheries policy (CFP), aimed to improve data collection andto provide funding for the research. All this in order to identify the best methods toprevent the seabirds are still being murdered.
Rory Crawford, policy Director of the Global program of marine birds of BirdLifeInternational, recalled: "Have demonstrated, through the work of the task groupalbatross of our team in longlines and ships engaged to trawling the world, as a focusof collaboration, working in close collaboration with the fishing industry, is able tosignificantly reduce the incidental catch of seabirds".
