European decision to maintain the practice of overfishing further endanger marine ecosystems - and increases risks for species like tuna and salmon.

Marine species have suffered a new blow in its campaign against the agonizing extinction. At the last meeting of the Ministers of Fisheries of the European Union was determined that the 27 member nations can continue to practice the technique known as trawling, contrary to expectations of environmental groups. Trawling is a method of fishing that involves actively pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are dragged along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously (double-rig and multi-rig).

In other words it is to pull a boat, a large network at depths below 200 feet, sweeping the sea and carrying not only as fish species of lower commercial value which are then played, without life, back to the sea. Experts estimate that a few weeks of this practice are sufficient to destroy the ecosystems that took thousands of years to form.

"To capture one or two commercial species, the trawl boats pulling large nets armed with metal plates and heavy rollers by the seabed, turning the soil and spraying everything in its path," says a report of the Deep Sea Conservation Coalition, an alliance of more of 70 scientific and conservation groups fighting for quotas for fishing on the planet. A study published in September found that the technique is more damaging to nature than all other human activities combined.

The culprit, again, is the appetite of a growing human population. Over the past 50 years, the withdrawal of these animals in the oceans has increased more than fourfold. The technological improvement of fishing fleets and the exploration of areas previously preserved were crucial to more than 77.9 million tons of fish and seafood started to be extracted from the seas every year.

The increased consumption of large predators such as tuna and salmon made the country ceased to restrict fishing to their exclusive economic zones stretch of water that stretches for 370 km up the coast. China, the biggest consumer of the planet, for example, cut its seas of 9.9 million tonnes of fish annually, but consumes 13.6 million tons. Called in the open sea, where there are no laws regulating the activity of fishing has increased almost tenfold from the 1950s. The jump was 1.6 million tons to 13 million tonnes.

The removal of species from the top of the food chain is the biggest damage to ecosystems. SeafoodPrint The study, released today, says that fishing for a kilo of tuna has an impact 100 times greater than that of a kilo of sardines. The justification of the researchers is that, every day, a specimen of the predator to eat their own body weight in lesser beings to stay alive. A tuna of 450 pounds eats smaller fish up to 15 thousand per year. Soon, the death of such an animal means a much greater loss than it may seem.
