Eastern Atlantic Purse Seine Tuna Fishery Improvement Project

e20171219_logo_panda“The Atlantic Ocean produces around 350,000 tonnes of tuna every year – about 10 percent of the world’s tuna catch. This is mostly made up of skipjack (Katsuwonus pelamis), yellowfin (Thunnus albacares) and bigeye tuna (Thunnus obesus). These tuna species are fished mainly in areas of the Eastern Atlantic where large currents converge off the coast of Gabon and where there are upwelling deep waters and nutrients off the coast of Guinea.

Tuna in this fishery is caught using various methods, with the purse seine method used to catch the majority of tuna for the European market. Purse seiners use large nets to encircle and capture whole schools of tuna. The use of sophisticated electronic devices, such as echo sounders, sonar, track plotters and fish aggregation devices (FADs) have helped fishers haul record numbers of tuna in recent years. But while this is a highly efficient fishing practice, there are significant uncertainties about the effect of purse seining on tuna stocks and the surrounding ecosystems.”
