The study aims to evaluate the level of adaptation of the financing service to demand, the improvement of income and the level of insertion in the formal financial market of fish farmers in the San Martín region. Among the main results, we highlight the high level of satisfaction with the service among fish farmers (76%), as well as the impact that the credit has had on the productive units, as 73.5% of those in charge of them indicated that it has contributed to increasing their income, with this increase generally being greater than 10%.
