Silvering index coefficients from Caroline Durif (2009) to predict silvering stage from morphological parameters
Classification scores are calculated by multiplying the metrics BL = body length, W = weight, MD = mean eye diameter (Dv+Dh)/2, and FL length of the pectoral fin, with each parameter p as S=Constant+BL*p(bl)+W*p(W)... The stage chosen is the one achieving the highest score
