PERU fishing with guts to report…
Scientists have claimed that warmer temperatures are absorbing oxygen from the water even at sea, so vast expanses of deep ocean have become hostile to marine life.
This lack of oxygen has been found through behavioral changes Fish, as the case of predator like Marlin and Sailfish are swimming near the surface, rarely using his formidable power to dive into the deep to pursue dams, reported National Geographic.
“Two hundred feet below, there is a train load of water with low oxygen fired toward the surface”says William Gilly, a marine biologist at Stanford University's Hopkins Marine Station in Pacific Grove, California. However, “with all the hype about ocean issues, it has not received much attention.”
Biologists believe that the world's low-oxygen areas have expanded by more than 1.7 million square kilometers (4.5 million square kilometers) in the last 50 years, a phenomenon that could transform the seas as well as the
Therefore, scientists are debating the amount of oxygen that is lost stimulated by global warming, and how much is driven by natural cycles. But they agree that climate change will generate a propagation losses and perhaps even accelerate.
Over the next decade, researchers investigate whether this change would foster marine creatures – – Sailfish, Shark, Tuna, Swordfish and Pacific cod and small Sardines, Herring, Mackerel Shad and eating – – in narrow bands of oxygen-rich water near the surface.
Moreover, biologists have noted that by coming together with his prey seems to be doing at a little greasy larger fish as they consume less energy in hunting. But living in such a compressed area can also be accelerating the decline of top predators such as tuna, sailfish, marlin and making them more accessible to fishing fleets.
Given these facts, most researchers project that oxygen loss continue driving many species to the surface, reducing habitat for some and concentrated as prey for birds, turtles and other predators surface.
