Fishing into the sea is nearly sustainable
24th February, 2018: According to a study published in the
journal Science, the fishing activity of humans has already covered more than
half of the ocean spread as of today. The researchers have derived this information
by analyzing the vast amount of data generated by the anti-collision beacons on
ships. In the process, the researchers have tracked more than 70,000 ships
roaming round the globe for fishing in deep seas.
The data of 2016 suggests that these ships have travelled more than 460 million kilometers, which is about five times the distance from Earth to the sun.
The fishing hotspots are identified as the South China Sea, and the coastal areas of Europe, East Asia, and South America.
After estimating the areas of the sea, from which data could not be extracted, the researchers comes to the conclusion that a total of about 73% of the whole sea spread is already exploited for fishing purpose, which is much smaller than 95% as predicted by earlier estimates. The extra marines reserves could become like marine reserves supporting sustainable fishing, notes the study. Good news for the fishers!
