Safety on the beach
Jellyfish are attacking the Mediterranean. Biologists-marine painters, studying the waters, is known among the most numerous and diverse populations of marine fauna, are sounding the alarm. If these invertebrates will continue to proliferate at such a pace, will not stand not only marine life, but vacationers here in the summer tourists.
According to Professor Stefano Piraino of Salento University in southern Italy, all 300 (!) kilometers of the beach, which he managed to fly on April 21, swarming with jellyfish. Himself Piraino heads the project control the population of jellyfish in the Mediterranean sea. The shift of the biological balance in the waters in favor of the jellyfish is due, firstly, global warming and, secondly, is due to excessive capture of fish and other edible inhabitants. In addition to jellyfish, thousands of miles of the Mediterranean coast there is no release from tourists onlookers. These “scientists with the air of a connoisseur” and armed with smartphones and “Apple”, relentlessly chasing an umbrella. During the four years of work of specialists in the framework of the mentioned project, the population of jellyfish is only increasing. Experts attribute this phenomenon to global warming. Convince them that the data that come from other areas of the world: is there a process develops in a similar way. Piraino says that on the island of Lampedusa, where the annual resting of about three hundred thousand tourists, you can swim only week of the whole summer. The rest of the time the water is filled with jellyfish.
But that said, the biologist, studying jellyfish at the Institute of Oceanology of Barcelona Jose Maria Gili: “jellyfish have increasingly become a problem around the world, the Mediterranean is no exception. And the farther away from the shore, so they are more insidious and harder to fight them”. This spring off the coast of Valencia Catalogue and specialists of the Institute have recorded a surge of population flowing down jellyfish Pelagia noctiluca . which is one of the most poisonous members of the species. “They stretched for several kilometers along the coast, 30-40 individuals per square meter”,- said in an interview with the Spanish newspaper “ABC” an employee of the Institute Veronica Fuentes. “We discovered in the spring individuals are distinguished by especially large size”. What is most surprising, according to Gili is flowing down jellyfish came close to shore. The fact that large jellyfish are not out on the coast due to the difference of temperatures in comparison with the open sea. Suffered from jellyfish Sardinia, Sicily, Malta, and Israel and Lebanon, on the Eastern coast of the Mediterranean sea. According to Piraino, every summer in the waters of its victims flowing down jellyfish be at least 150 thousand people.
Along with the jellyfish to the surface once again POPs up the notorious human factor. The king of nature, with its global warming, insatiable catching fish, different kinds of sea walls, breakwaters and other man-made “wonders” designed to preserve the marvellous sandy beaches (here they are, those good intentions!) stimulates the growth of jellyfish population. Controlling the growth of predators polyols, which is not true of the larvae of the jellyfish. Now it multiplies exponentially.
As Gili said, “jellyfish on the beach – it’s like a message in a bottle. The sea seems to say to us: “Look what you did to me”. But tourism, according to Piraino, suffers not less. “The financial damage is huge, huge social problems. We are losing millions of euros”.
Of course, in the summer, jellyfish have always besieged the beaches of Catalonia, but 15 days was the maximum. Now on some Mediterranean resorts have decided to put six-foot mesh fence to protect the bathing area from the jellyfish.
Although probably the ideal means of protection from jellyfish sunscreen that prevents the ingress of secret poisonous stinging cells located on tentacles of jellyfish.
Piraino believes that scientists still know very little about this species, especially since it was difficult to predict to what extent will multiply and the population, and the problem, encountered in full growth this summer. “We know, of course, do not know, but be on the alert to needs,” he says.
However, that alone strikes fear and terror, the other is affection. In China, for example, a gelatinous creature with treacherous disposition is considered to be one of the delicacies. In China they are not only eaten during the last five thousand years, but also sending to other countries: annual export volume amounts to 20 thousand dollars. The case is obviously profitable if now catching jellyfish started and the Chinese living in Sicily.
Particular attention scientists pay for one type of jellyfish that live in the Mediterranean sea. This is Cotylorhiza tuberculata, the Mediterranean “fried” as it is called. Today out of her body highlighted substances which can help in the treatment of cancer, and antioxidants. In short, who hinder us, that will help us and…
