Russian authorities have raided the offices of several fishing companies in the Russian Far East, sources told IntraFish.

The raids were carried out by officers from the Russian Federal Security Bureau (FSB) and the Federal Antimonopoly Service, two sources in the industry said.

According to the sources -- one whose own company was raided, and another citing someone who visited several companies in the area last week -- the raids were carried out around late May and early June.

Raided companies included Dalmoreprodukt, Vostokrybprom and Sovgavanryba, whose documents were reportedly copied and all management interrogated, sources told IntraFish.
