Discriminant functions for morphometric measurements determined by a discriminant 
function analysis for all individuals, Sebastes mystinus (blue rockfish; n= 68) and S. dia- 
conus (deacon rockfish; n= 52) combined, and for individuals over 150 mm SL, S. mystinus 
( n=37 ) and 8. diaconus {n= 36). Most extreme coefficients are indicated in bold.
