2. General Description -Behnke (1973 a) describes living specimens
as spots on body large, round or oblong; largest, most prominent
spots in area posterior to a line drawn from origin of dorsal
fin to origin of anal fin. Spots on S. c. stomias are typically
larger than in other subspecies. Spots generally absent from
head; occasionally on anal fin. Coloration may be brilliant,
almost gaudy, particularly on males during the breeding period.
Colors on sides of body vary from dull brass to bright golden
yellow with pink or red hues extending around lateral line, but
not in a distinct band as in rainbow trout. Ventral region
cream to orange or red. Orange or red often suffusing lower
fins. Cutthroat mark usually crimson, sometimes orange. Also
see Table 1.
