Growth estimates of weight specific growth rate (SGR) in % per day (mean ± SD) for different datasets from different species and at different growth stages, with three inputs of normalized weight, normalized activity ratio of trypsin to chymotrypsin (T/C ratio), and normalized condition factor (CF), using different trained models from each dataset and combinations of different datasets.

The values in parentheses are mean squared error (MSE) calculated from real SGR and estimated SGR values. The network time scale λ = 0.3 for the models from the same dataset, and λ = 1.0 for the other models (see Table 1).
