The project aims to simplify the communication of technical information between rural extension agents and fish farmers, focusing on production and management in fish farming. Its main innovation is a paper platform with information on both sides and overlapping movable discs that address management in eight tank sizes. The opposite side features a circular calendar that, when aligned with the fry population date, automatically generates a management calendar, including growth indicators and feeding guidelines. This approach simplifies production planning, avoiding complex calculations, helping producers to size the number of fry, plan feed purchases and reduce losses and environmental impacts, aiming to maximize profits in fish farming.
