Resumen
This research has been proposed to analyze the value chain of the black shell (Anadara tuberculosa) for the sustainable use in concession areas of the Bunche and Sálima communities, to users of the Mangrove Forest Ecosystem of the Muisne canton, Esmeraldas province. The entire collection and commercialization process was determined through surveys conducted to different focus groups in this field, meanwhile in comparative contrast to size, mortality and abundance, plots were established in 4 different areas. The chain links are: collection, storage - trade and final market - final consumer. The size distribution for A. tuberculosa in Bunche was 1,8 - 6 cm and in Sálima of 1,6 - 5 cm. For A. similis of 2,5 - 4,8 cm in Bunche and in Sálima de 2,6 - 4,9 cm. The population density of A. tuberculosa in Bunche registered in the mangrove area 3.5 individuals / m2, the area close to the shrimp farm 1.15 individuals / m2 and the area close to the population and disturbed 1 individuals / m2. In Sálima the mangrove area 3.9 individuals / m2, the area close to the shrimp farm 1.2 individuals / m2, the area close to the population 0 individuals / m2 and the zone with disturbance 0.12 individuals / m2. Size for A. tuberculosa and A. similis showed significant differences between areas and localities, but abundance for A. tuberculosa showed significant differences between areas but not between localities, however, A. similis presented significant differences between areas and between localities. Mortality for A. tuberculosa showed significant differences in the locality of Sálima, but not in the locality of Bunche and A. similis did not present significant differences for areas or localities. Soil tests were carried out where the studied variables are within the optimum levels for the shell survival. Finally, sustainability strategies were proposed.
