Agriculture Fishing Senegal has a exclusive fishing zone that has been regularly breached in recent years (). It has been estimated that the country's fishermen lose 300,000 tonnes of fish each year to illegal fishing. The Senegalese government have tried to control the illegal fishing which is conducted by fishing trawlers, some of which are registered in Russia, Mauritania, Belize and Ukraine. In January 2014, a Russian trawler, Oleg Naydenov, was seized by Senegalese authorities close to the maritime border with Guinea-Bissau.
