This exploratory study analyzes the oyster cooperative "Leonor Cuadras" in La Reforma, Angostura, Sinaloa, Mexico. Founded in May 2023 by four women and sponsored by the seafood company Marine Edén SA de CV, this cooperative aims to be an alternative livelihood model led by women, promoting environmental sustainability and gender equity. The NGO SUCEDE supports this project, which focuses on the individual, social, and environmental healing of La Reforma, a fishing community facing significant socioeconomic challenges. This study provides a detailed view of the first months of operation of the "Leonor Cuadras" cooperative, offering practical recommendations for its consolidation and expansion, as well as its reproduction as a sustainable development model with other members of the community and the Sea of Cortez region.
