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.
