Typology of small-scale fishing gear impact on seabirds in the Senegalo-Mauritanian Upwelling [résumé]
Situated in West Africa, Senegal has 700 km of coastline characterized by a large Eastern Boundary Upwelling Ecosystem providing significant biological productivity. Small-scale fishing plays an important role in the national economy of Senegal. The fishing gear used has a potentially direct or indi...

Situated in West Africa, Senegal has 700 km of coastline characterized by a large Eastern Boundary Upwelling Ecosystem providing significant biological productivity. Small-scale fishing plays an important role in the national economy of Senegal. The fishing gear used has a potentially direct or indirect impact on seabirds. To examine and evaluate this impact surveys were conducted on eight landing sites. Field surveys (2-3 days) took place in 2015 based on a standardized interview with questionnaire conducted with 225 small-scale fishermen. The results obtained indicate that longlines are the fishing gear that causes the highest rate of annual accidental seabird catch (63 % of seabird caugth (n = 702)), followed by handlines (16%) and anchored gillnet (6 %). The Pomarine Skua (Stercorarius pomarinus) is the most captured bird annually (29 % of total captured birds), closely followed by the Cory's Shearwater (Calonectris diomedea) (28 % of captured birds) and the Northern Gannet (Morus bassanus) (13 % of captured birds).
