Plots of diagnostic morphometric characters versus 
standard length of Sebastes aleutianus (rough- 
eye rockfish, open diamond) and S. melanostictus 
(blackspotted rockfish, closed square). (A) Dorsal-fin 
spine I length, (B) dorsal-fin spine IV length, and 
(C) gill raker length. The first and fourth dorsal-fin 
spines and gill rakers are longer in most specimens 
of S. melanostictus than in S. aleutianus. 
separation, one would identify individuals with a 
score above 0 as S. melanostictus and those below 0 
as S. aleutianus.

Plots of principal component (PC) scores for morphometric and 
meristic characters for Sebastes aleutianus (rougheye rockfish, 
open diamond) and S. melanostictus (blackspotted rockfish, 
closed square). (A) Morphometric characters only, (B) meristic 
characters only, and (C) morphometric (PC2) versus meristic 
characters (PCI). Differences among specimens along the major 
axis of dispersion in the morphometric analysis (PC2) were 
primarily due to longer dorsal-fin spines, anal-fin spines, and 
gill rakers in S. melanostictus. The slight separation among 
specimens along the major axis in the meristic analysis (PC2) 
was primarily due to higher counts of gill rakers, lateral-line 
pores, and dorsal-fin rays in S. melanostictus.
