For lovers of the sea 2014 was an annus horribilis, especially for the people of Abruzzo.
Last bathing season began with bad news: the waters of the region ranked among the dirtiest of Italy. The rest of the situation does not go better between fishing effort and increase in waste piled on the shoreline after every storm. The situation can not be said to be better for fresh waters: the state of the rivers one of continuing deterioration.
The last glimpse of summer has also “given” an episode that will remain indelible in the collective memory: the night between 11 and 12 September seven sperm whales have beached sull’arenile Punta Aderci, Vasto. A female was pregnant. Of those wonderful animals four were driven back into the sea with a successful supportive crowd of volunteers. The three carcasses (including exemplary pregnant) were subjected to necropsy examinations. Among the hypotheses to explain what happened one of the most credible is the presence of gas accumulated in the blood for an emergence too rapid.
“It is not difficult to imagine an anthropogenic cause, though perhaps certainties we will not ever,” says the WWF Abruzzo. “The strandings still remain enigmas of marine biology: always occur, but it is a fact that human action has made the phenomenon more frequent.”
In 2014 you are stranded around thirty cetaceans, mostly bottlenose dolphins along the coast of Abruzzo. Of these most came ashore already dead, others have taken off, but we do not know if they survived or simply have gone to die elsewhere.
Also 53 species of turtles Caretta caretta, a priority species for environmental protection, have been found stranded or entangled in fishing nets.
“A trend unfortunately on the rise,” always analyzes the WWF “in just the first two months of the year just started recording 34 dead specimens in a non-natural (most by suffocation). Strandings of these reptiles are appearing frequently in the Adriatic. One reason is probably the intensive commercial fishing, particularly with bottom trawls and gillnets. Turtles frequent the northern Adriatic mainly to feed and usually move south in late August. In recent years, because of climate change, the sea is warmer and in the aftermath of biological rest (August 11 to September 22) are still with us when the boats return to sea in droves to rebuild after the forced break … A possible solution to combat this die-off could be related to fishing techniques eco-friendly since turtles are endangered species at high risk or even a revision of the plans for fishing “measured” according to the marine area of reference and its specific needs. ”
Fishing is a major cause of serious injuries or deaths, but certainly not the only, stress the animal, “the impact with the boats, for example, are relatively frequent in the busiest as the Adriatic sea, without forgetting the weight increasing pollution.
Turtles are on the earth long before the appearance of man; have been able to survive the mass extinction of the dinosaurs 65 million years ago; exceeded glaciations and other extreme natural events. They are equipped with sophisticated systems for orientation and a series of devices for hydrodynamic swim for thousands of kilometers. Are perfectly equipped for any natural event, but not for unnatural ones. Precisely for this reason we have to do something before it’s too late for them and for us all. “
