“…The research was carried out from January to October 2019 in the Jambelí archipelago, El Oro province, Ecuador (Figure 1), one of the most important shellfish capture areas in the Republic of Ecuador due to its high landing volumes [24], similar to those of the province of Esmeraldas. The population under study was integrated by 565 individuals, made up of the strata of shellfish collectors, managers of shellfish associations, traders, and restaurants of the A. tuberculosa production chain, based on the information collected from the Unión de Producción Pesquera Artesanal de El Oro, Ecuador (UOPPAO), from the Asociación de Empresarios de Comercio y Servicios de la Provincia de El Oro, Ecuador, and through the on-site review of the restaurants located on the islands and in the area's coastline.…”

The bivalve mollusk, Anadara tuberculosa (Black Shell, in Spanish Concha Prieta), is found on America’s Pacific coast, where it is harvested for subsistence and commercial markets. This paper aims to diagnose the performance of the black shell’s value chain. We also identify several challenges that must be addressed to improve the sustainability of the black shell fishery in Ecuador. The applied methodology was quantitative and descriptive. Its design was non-experimental, field, cross-sectional and ex post facto. The investigation was carried out from January to October 2019 in the Jambelí archipelago, El Oro province, Ecuador. The study population consisted of 565 individuals, shellfish collectors, shellfish associations managers, traders, and restaurants from the A. tuberculosa production chain. The sample size was estimated at 222 informants. The type of sampling used was probabilistic, random, stratified, and with proportional allocation, with an effective participation rate of those selected of approximately 80%. The questionnaire was applied personally through the structured survey method, in writing, in the work area, and with their consent. The performance of the value chain was diagnosed in the dimensions of productivity, competitiveness, and quality of life, reaching a 75.1% index, a result that indicates that the value chain has a moderate to good performance level. The competitiveness dimension reached the highest performance, followed by productivity. Quality of life was the dimension with the lowest performance. The value chain can be improved if the following challenges are met: (1) Restoration of the mangrove ecosystem, (2) Promotion of low-intensity shellfish aquaculture, (3) Good sanitary management and purification, (4) Promotion of value-focused ventures, (5) Strengthening of organizations and agreements for the use and custody of mangroves, and (6) Strengthening of institutions that contribute to the advancement of these challenges.

The bivalve mollusk, Anadara tuberculosa (Black Shell, in Spanish Concha prieta, "CP"), is found on America's Pacific coast, where it is harvested for subsistence and commercial markets. This paper aims to diagnose the performance of the black shell's value chain. We also identify several challenges that must be addressed to improve the sustainability of the black shell fishery in Ecuador. The descriptive methodology was quantitative, with a non-experimental, field, cross-sectional, and ex post facto design. Similar questionnaires were designed, validated, and applied to each link in the production chain to collect information. The performance of the value chain was diagnosed in the dimensions of productivity, competitiveness, and quality of life, reaching a 75.1% index, a result that indicates that the value chain has a moderate to good performance level. However, the value chain can be improved if the following challenges are met: 1) Restoration of the mangrove ecosystem, 2) Promotion of low-intensity shellfish aquaculture, 3) Good sanitary management and purification, 4) Promotion of value-focused ventures, 5) Strengthening of organizations and agreements for the use and custody of mangroves, and 6) Strengthening of institutions that contribute to the advancement of these challenges.

“…El archipiélago de Jambelí representa una de las zonas de captura de concha de mayor relevancia en la república del Ecuador por sus volúmenes de desembarque [7]. En el año 2011 se estimó una captura total, en los principales puertos de desembarque de la costa ecuatoriana, del orden de 30 millones de individuos, de los cuales aproximadamente el 40% se extrajeron en el archipiélago de Jambelí [8], lo cual indica que esta zona cuenta con unas características relevantes para el estudio de la cadena de producción de la A. tuberculosa (CaPAT).…”

Quantifying the performance agribusiness management model of the production chain of the Anadara tuberculosa called in Ecuador "Concha Prieta" o black shell is the object of this research. To this end, a quantitative, field, cross-sectional, "ex post facto" methodology was applied, through the application of 4 structured questionnaires. It was concluded that despite the low levels of agribusiness management, the performance of the value chain reaches an intermediate level, mainly due to the relevant characteristics of the black shell, the great demand in the Ecuadorian market and neighboring countries.
