The Russian trawler Oleg Naydenov was recently arrested and escorted in to the Port of Dakar by Senegal navy vessels. If found guilty it faces a doubling of the usual fine, and the arrest has also sparked an appeal by African coastal nations for an opinion from the International Tribunal for the Law of the Sea. A French military plane flying over Senegal's Exclusive Economic Zone detected some of the same vessels that had been stripped of their licences continuing to fish in these waters.
