Résumé : Fishing is a traditional activity that is widespread in West Africa. One of the greatest problems for fishermen and a cause of lack of food accessibility is the difficulty in conserving fish. Drying is a widely used technique in sub-Saharan Africa for preservation and weight reduction of fish. However, drying is a complex process, making the construction of efficient drying devices challenging. This paper presents the construction and installation of five mobile fish dryers in Mali and the development of a method for their use. This last point was realized on one of those dryers. The performances achieved far exceeded that of traditional solar dryers as drying was faster drying and the fish were not contaminated by being exposed to non-filtered air. Furthermore, a construction and user manual were written for the local fishermen which was well understood as the fishermen were able to disassemble and reassemble the dryers when they were required to be moved.
