The Fish Market, located next to the historic Tablado Market in the city of Santarém-PA (Fig. 1A and 1B), has functioned as a commercial hub for recording and gathering fish landings since 2009. The traditional practice for selling fish takes place from Monday to Sunday, starting at 5:00 am and ending at 12:00 pm. The market receives products from diverse areas surrounding the city of Santarém, including neighboring municipalities such as Alenquer, Monte Alegre, and Curuaí. The landings were recorded by a market attendant (clerk) who diligently made daily entries in a notepad. The entries comprised the weight of the fish in kilograms, the name of the buyer, the date of the record, and the name of the landed fish (the known name of the fish). The daily landing records were stored in notepads. The transformation of handwritten notes into digital form using spreadsheets was carried out by student volunteers, who are also known as monitors. The monitors were initially presented to the market manager, who authorized access to the attendant's notes. As part of their training, the monitors also observed the sales dynamics during registration and subsequently extracted the data from the notebook using photocopies or digital photographs. The data was subsequently converted into electronic spreadsheets in the laboratory.
