SUMMARY:

AGUIAR, Antonio Wilson Fornero. Mathematical models to estimate food consumption for Nile Tilapia, Rainbow Trout and Tambaqui. 2019. 45p. Dissertation (Masters in Animal Science). Zootechny Institute, Federal Rural University from Rio de Janeiro, Seropédica, RJ, 2020. 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 three species of cut fish most reared in the State of Rio de Janeiro (Nile Tilapia, Rainbow Trout and Tambaqui) . When 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 three fish species and their food consumption will be elaborated. . Based on the data collected, the parameters of the equations of four non-linear models (Gompertz, Von Bertalanffy, Brody and Logistical) will be estimated for the two variables studied (Growth in weight (g) over time and Food consumption (g) at over time). Adjustment evaluators (AIC, BIC, biological interpretation and others) will be adopted to select the best models or models. Finally, an estimate of the cost of food will be carried out with current values of the feed markets adopting the model of best result of food consumption.
