Figure 3: A composite dendrogram for hierarchical cluster analysis of predicted PI Fish were sorted into different maturity levels using the following groupings: group 1: 0.05<PI<0.10; group 2: 0.10<PI<0.15; group 3: 0.15<PI<0.20; group 4: 0.20<PI<0.25; group 5: PI>0.2). Each number on the x-axis represents one sturgeon blood plasma (average spectra (N=30)) randomly selected both Idaho and California during Period I and II (2007-2009). This segregation analysis model is representative of one of the ten models validated by using fish samples from 2010 from California (N=10). An asterisk marks a sample used for model validation and subsequent validation challenge.
