摘　　要：Pelagic fish,including sardines and anchovies(Order Clupeiformes),are the most common species taken by artisanal marine fisheries along the Togolese coast.We investigated fisher involvement as well as fish captures over a period of 10 years,particularly of the European anchovy(Engraulis encrasicolus).Our results indicate that 60%of fishers operated from the Loméfishing harbour,most fishers being Ghanaians working seasonally in Togo.63.7%of all the fishers used canoes with outboards,a higher percentage compared to the previous decades.Seven fishing gear type were identified,with bottom gillnet and surface gillnet being the most commonly used.However,in the most important fishing camp in the country in terms of fish production(Loméfishing harbour),all fishers used shark nets.Overall,fisheries catches did not change significantly across years,but anchovy fishing effort and catch per unit of effort(CPUE)declined over the study period,suggesting some depletion of the species stocks on the Togolese coast and a demotivation of fishers.
