Sharks recently spotted near Russia's Vladivostok have become a topic of discussion on social media. Sharks were reportedly caught near the Putyatin and Dunay settlements in the Primorsky region, and encounters with these species have been recorded in the area.
Biologist's statement
Vladimir Dolganov, a PhD biologist at the Marine Biology Laboratory of the National Scientific Center, told RIA Novosti that the sharks do not pose a problem for humans.
Dolganov said, "Their main population is in the south. They came here and will return in the autumn. They follow the fish, just as wolves follow deer. In nature, everything is purposeful and normal. In the autumn, they will all gradually retreat back south."
No danger
The biologist stated that humans are not part of the sharks' food chain and do not exist in their genetic memory. According to records from the World Shark Research Commission, there are about 100 shark attacks annually, roughly 10 of which are fatal.
Dolganov noted that people lose their lives far more often in various everyday situations and traffic accidents. He said some media outlets sensationalize the sharks' normal annual arrival in Primorsky, causing tourists to fear entering the sea.
"But there is no problem for humans, no danger at all," he added.
Background
A previous statement by TINRO (Pacific Branch of VNIRO) indicated that the sharks arrived in Primorsky following an increase in the sardine population.
In the second half of 2011, three incidents of holidaymakers encountering sharks were recorded in Primorsky. Since then, no shark attacks on humans have been reported in the region, though locals occasionally capture their encounters with sharks on video.
