Development and evaluation of Nile tilapia (Oreochromis niloticus) body composition models

Mathematical models can be used as an alternative to conventional analytical methods (AOAC), allowing to indirectly estimate the body composition of fish without, in some cases, being necessary to sacrifice animals. To develop models with high predictive capacity, in addition of having access to representative data, it is important to use calibration methods that minimize the estimation of the generalization error.
