Evaluación de la reintroducción de concha prieta (Anadara Tuberculosa, Sowerby,1833) en el área de concesión de ASOPROPECHU.

Abstract

Research work titled "Evaluation of the Reintroduction of Black Clam (Anadara tuberculosa, Sowerby, 1833) in the ASOPROPECHU Concession Area" aims to evaluate the viability of reintroducing Anadara tuberculosa in the ASOPROPECHU concession, located in the "El Churo" community, Pedernales canton, Ecuador. The study analyzes growth, survival, and effects on the marine ecosystem in three sampling sites: El Churo, El Morro, and Los Ranchos, over a period of 120 days. The results showed that the "El Churo" site provided the best conditions for survival, with a 100% survival rate at some points, while "El Morro" and "Los Ranchos" exhibited greater variability, with higher mortality rates and lower survival in some areas. In "El Morro," survival reached 56% at best, while in "Los Ranchos" it was 62%. Statistical analyses, such as ANOVA, revealed no significant differences in the initial weight of specimens between the sites, suggesting homogeneous conditions at the start of the study. This work highlights the ecological and economic importance of Anadara tuberculosa, which is key in the local artisanal fishery and mangrove ecosystems. Additionally, recommendations are proposed to improve management practices, favoring sustainable exploitation and contributing to the long-term conservation of the species, offering a model that can be replicated in other areas to ensure conservation and the well-being of communities dependent on this resource.
