PETROPAVLOVSK-KAMCHATSKY, April 13 (RIA Novosti) - A Sierra Leone-flagged ship has been stopped by border guards in Russia's Far East Sea of Okhotsk on suspicion of poaching, a regional coast guard spokesman said on Monday.

Border guards said the vessel had no documentation allowing it to fish in Russian waters or ship seafood. The vessel has been taken to a port in Petropavlovsk-Kamchatsky for further investigation, the spokesman said.

This year, Russia launched a crackdown on the illegal export of crab and other seafood. Since January, Russia's border guards have returned to the sea more than 246,000 live crab, with an estimated commercial value of over 170 million rubles ($6.1 million).
