SUMMARY:

 AGUIAR, Antonio Wilson Fornero. Mathematical models to estimate food consumption for Nile Tilapia (Oreochromis niloticus) and Tambaqui (Colossoma macropomum). 2021. 47p. Dissertation (Masters in Animal Science). Zootechny Institute, Federal Rural University from Rio de Janeiro, Seropédica, RJ, 2021. Precision technology is inserted every day into the rural environment, and for that, research with mathematical models that can be adopted to improve management is necessary. This research has the objective of elaborating non-linear curves from equations consolidated in the scientific environment for the consumption of diets for the two species of cut fish reared in the State of Rio de Janeiro (Nile Tilapia and Tambaqui). Obtaining information about growth over time and feed conversion for each growth phase for the fish species to be studied, growth curves over time for the fish species and their food consumption will be elaborated. Based on the collected data, the parameters of the equations of four non-linear models (Gompertz, Von Bertalanffy, Brody and Logistical) were estimated for the two variables studied (Growth in weight (g) over time and Food consumption (g) at over time). Adjustment evaluators (biological interpretation and studentized waste analysis) were adopted to select and verify the quality of the models. The data generated on feed offer or consumption for Nile tilapia and tambaquis, were adapted to the Gompertz and Logistics models, respectively. Mathematical models, such as the Gompertz and Logistic equations, can be used to estimate consumption or feed supply for Nile tilapia and tambaqui, but rigor in the evaluation criteria and adjustments is necessary.
