Changes to shark fishing boost sea lion population in south China coast

By Kim Soo-jin


Seafloor shark populations have soared in the recent past as a result of increased fishing, a study published Tuesday shows.


Shark fishing increased from 845 shark carcasses removed in the previous year to 1,130 in 2015 due to a sharp decline in commercial fishing, said Park Eun-jin, associate professor of marine science at South Korea's Yonsei University.


In addition, there has been a slight increase in commercial fishing in the past year, with 673 carcasses removed as of last month from coastal waters in north-central China's Jinan Province, she added.


Park said the decrease in fishing and the increase in commercial fishing are largely due to changes to how people in China conduct their fishing.


"The increase in commercial fishing has come in reaction to the shark hunt," she said, "by encouraging people to bring small fish with them when they go fishing. But the shark hunt was still a popular way of catching shark, so more and more people started catching smaller sharks and fish when they go fishing.


"The fishing effort has also changed, with more families taking part. It's easier to catch large sharks and larger fish after the fishing effort has been increased."


This year there have been 996 shark carcasses removed from the coast of Ningbo City, where the shark-fishing has been taking place for nearly eight years, and 785 from coastal waters of Qingdao City and Xichuan.

The world's highest killing of sharks by humans began at the end of May 2012, when a massive shark hunt was conducted off the coast of Borneo to try to save the country's largest mammal, which had been dwindling rapidly due to habitat loss.The largest remaining shark found by scientists at that time was a 20.7 meter (79 foot) shark, killed about 500km away from the original hunt site in November.Since then, many sharks have been killed in different areas, but the most popular is the largest, which has been recorded at a depth of nearly 300m (934 feet) in the Indonesian city of Bali.
