Sharks increasingly endangered















The alarm for the survival of sharks arrive by the Congress of the American Society for the Advancement of Science (AAAS) being held in Boston where they were presented the latest studies on the state health of the great predator of the seas.
Including a startling research that shows how they run around underwater in these animals have deeply entrenched habits that make them look like the drivers, routes and rest stops with the applicants.
Among the species most endangered tiger and the hammer, declined by 95%. One of the solutions

desirable in an effort to preserve these majestic animals is the creation of new marine protected areas, especially in those places that sharks use it as the "underwater highways." In their travels, several studies have established, do not move it at random searching for prey, but always follow the same routes, but these are also the most threatened wild fisheries in recent decades has decimated several species.
In addition, researchers at the University of California at David, following with GPS devices movements of hammerhead sharks in the eastern Pacific, have identified that the route followed by the animals between Mexico and Ecuador is full of "resting" , usually in the vicinity of islands. "I'm not missing in the oceans but will collect in some 'highways' that pass through specific points - says Peter Klimley, who led the study - so to save them should strengthen the reserves around these areas and replace fishing with other activities, such as tourism. "
An indirect confirmation of the validity of this research comes from a Another study by Stanford University on the American white sharks that come to similar conclusions. In winter, scientists have found, leave the adult areas of central California where they reproduce and are looking for warmer waters to the south along this route has been identified an area near Hawaii, so popular that the researchers' They called The white shark cafe.
"We called cafe because we are not yet certain whether sharks are attending the area to feed or just to meet," said Salvador Jorgensen, who led the study. "Once they have left the area - he added - the fish come back every year in exactly the same point." Creating marine reserves in similar areas is not the only measure to be taken to put the Sharks out of danger. Another intervention suggested by the experts is the restriction of fishing quotas defined by scientific criteria for establishing protected areas.
