A shark was caught at sea. On the 12th, a salmon shark was caught on a fishing boat. The salmon shark was 2 meters long and weighed 150 to 180 kilograms.
Climate change has led to the appearance of large sharks on the Korean Peninsula. Last year, there were 29 reports of large sharks being caught or spotted on the east coast.
In 2022, there was only one incident. This year, the frequency is expected to increase. From the beginning of the year to the beginning of this month, fishermen have caught a total of 14 sharks while fishing.
The frequency of these attacks is high, so summer vacationers are advised to be careful during July and August. The National Fisheries Research Institute (NAFI) recently announced that it would use warm-water fish as bait, based on the fact that the catches of warm-water fish species have increased due to the rise in water temperatures in the Korean Peninsula.
The National Fisheries Science Institute and the Donghae Fisheries Research Institute have estimated that the sharks caught together in fixed nets in Gangwon Province and North Gyeongsang Province since the beginning of this year.
The stomach contents of 11 large sharks were analyzed. The results showed that they had been feeding on a large number of warm-water fish species, including yellowtail, filefish, and squid.
The average catch over the past decade has been 6,709 tonnes, a 430% increase from the average catch of 1,265 tonnes some 30 years ago.
The National Institute of Fisheries Science said, "We currently have no data on the frequency with which sharks have been spotted off the coast of Busan.
"More research is needed, but it's possible that, as in the east coast case, sharks were caught in the same waters as they were chasing food."
A total of six fatal shark attacks have been reported in the country.
Experts say, "If you spot a shark while knee-deep in the sea, you should immediately move to land. If you are chest-deep in the water, the shark will not recognize you as prey.
You should try not to move if possible."
