The World Wide Fund for Nature has launched a campaign to ask governments and companies to reinforce measures against the poaching of salmon in the Russian Far East.

The drive by the WWF, which raises funds for projects to conserve endangered species, comes against a backdrop of rampant salmon poaching in the area.

It plans to ask the Japanese government to step up measures to eliminate illegal salmon fishing near the maritime border with Russia. Japan is the world's No. 1 importer of salmon products.
