“…In the economic productivity subdimension, it was evidenced that the participants in the CP production chain have always experienced moderate improvements in their income (35.4%). In comparison, 23.1% experienced that their income has rarely increased [15]. However, the monthly revenue per shell collector was estimated between 427 and 640 USD, a range below the basic family basket in Ecuador, 712.11 USD, equivalent to a 40% to 10% deficit.…”

The productivity dimension investigated whether production was sufficient to satisfy customer demands, as Prado-Carpio et al [15] indicated.

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.

“…La metodología consistió en una exploración y análisis de publicaciones relacionada con el tema, con énfasis en la producción académica generada a partir de la investigación doctoral de Prado-Carpio (2020), Prado-Carpio et al 2019;2020a;2020b;2020c). Una vez procesada la información de manera integral, analizados los antecedentes obtenidos de la estudio bibliográfico, los resultados obtenidos y la experiencia de los investigadores, se priorizaron las estrategias más importantes para esta cadena de suministro con base al desempeño reportado (Prado-Carpio, 2020;Prado-Carpio et al, 2020c).…”

El molusco bivalvo, Anadara tuberculosa, (concha prieta), se localiza en el ecosistema manglar de las provincias de El Oro y de Esmeraldas del Ecuador, donde está sometido a una relevante actividad de extracción. Este recurso es fundamental en la dieta alimentaria diaria, además de ser una fuente relevante de sustento económico de numerosas familias, además se está comercializando en todo el territorio ecuatoriano y con los países vecinos. El objetivo de esta investigación es plantear las estrategias que debe superar la cadena de valor de la concha prieta, para mejorar su aprovechamiento económico y social de manera sustentable. La investigación se realizó específicamente en el archipiélago de Jambelí, provincia de El Oro, Ecuador. La metodología descriptiva aplicada se basó principalmente en la revisión exhaustiva y análisis de material bibliográfico, fundamentalmente generado en los últimos años por los autores. A partir de esta información, complementada con los resultados de estudios previos sobre el desempeño de la cadena de valor de la concha prieta, compuesto por las dimensiones de productividad, competitividad y calidad de vida, se identificaron estrategias, cuyo logro coadyuvará a mejorar este desempeño: 1) Restauración del ecosistema manglar 2) Impulso de la acuicultura de baja intensidad de la concha 3) Buen manejo sanitario y depuración 4) Fomento de emprendimientos con enfoque de valor, 5) Fortalecimiento de organizaciones y de los acuerdos de uso y custodia del manglar y 6) Creación de un sistema institucional que contribuya al avance de estos retos.

Performance and Challenges in the Value Chain of the Anadara tuberculosa Bivalve Mollusk in Ecuador

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.
