Atualização do aplicativo AquiNutri com a adição de novas espécies para o cálculo de arraçoamento

Abstract

Fish farming has been growing and moving the Brazilian economy considerably. Among the essential activities for fish farming is the provision of feed in appropriate amounts for their development. In order to calculate the necessary amount of feed to be supplied, it is necessary to correlate some information, such as the biomass of the animals and the water temperature, and according to the feed rate, the amount of feed that must be supplied is calculated. To determine the amount of feed to be supplied daily to the animals, producers need to consult tables and perform calculations, and as a result, in 2017 the AquiNutri application was developed, which aimed to perform the calculations for the feeding of tilapia and pacus, in order to facilitate and optimize this task. Given the acceptance of the application by users, which was demonstrated by the numerous downloads from the Play Store, and the need to add new species for the calculation of feed, the objective of this work was to update the AquiNutri application, adding screens for the feeding calculation of tambaquis and carp. The application was updated using the App Inventor 2 platform, using the “design” tab and the “editor blocks” tab. The new calculation screens for the feeding of tambaquis and carp were developed with the same layout and algorithms as the calculation screens for tilapia and pacus. After updating, the application maintained the proposal of its first version, which was to present a screen with data input and output that is easy to interpret and intuitive for the user, performing the calculation properly for the feeding of new species.
