According to local media and the investigative newspaper Novaya Gazeta, more than 100 whales are being held in pens in Srednyaya Bay, near the city of Nakhodka.
Commercial capture of killer whales is strictly regulated and allowed solely for educational and scientific purposes, RIA-Novosti added.
RIA-Novosti reported that a local animal-rights activist launched a complaint with the police after unknown individuals stopped her from taking a picture of Srednyaya Bay.
Multimillion dollar export
These images and videos appear to show what environmentalists and locals say is part of a multimillion-dollar trade in capturing and exporting the marine animals to ocean theme parks in China.
“Where is it written that the biological resources of the country can be scattered left and right?” Novaya Gazeta wrote.
“Let us leave aside (temporarily) the ethical side of the question: yes, the capture and commercial exploitation of whales and dolphins is terribly unethical, but their capture — considering the poor fellows in terms of their multimillion dollar value — is also an economic crime.”
