  1. QDA to assign to a glass eel group EEM fluorescence intensities measured in the alizarin maximum bands and values of the ratios R. The model correctness rate, the percentages of each assignation (with the number of observations in parentheses), the fluorescence intensities quartiles and the ratios values means ± SD are presented for each group.
