Russian and Moroccan scientists are collaborating on the Great African Expedition to study the Atlantic fishing zone of Morocco, as part of an intergovernmental agreement with the Russian Federation and the Kingdom of Morocco. The research, conducted by the Russian vessel Atlantniro, has already yielded catches ranging from 0 to 660 kg per trawl, primarily mackerel. The expedition will also extend to other West African nations and the western Indian Ocean, covering 18 countries. This is the first such research since the 1980s and aims to provide current data on aquatic bioresources, potentially opening up new fishing areas.
