Description

The back and sides are olive green or muddy gray, shading to white on the belly. The body has scattered pale yellow or pinkish-yellow spots. There are no black spots or wavy lines on the body or fins. Small red spots are present on the lower sides. These are frequently indistinct. The fins are plain and unmarked except for a few light spots on the base of the caudal fin rays. S. malma is extremely similar in appearance to the bull trout

, included an account of this naming of the Dolly Varden Trout in one of his books.


In 1874, Livingston Stone, a naturalist working for the U.S. government wrote of this fish:
Also called at (Upper) Soda Springs the 'Varden' trout. … The handsomest trout, and, on the whole, having the most perfect form of all the trout we saw on the McCloud. Also, the only fish that had colored spots. This one was profusely spotted over most of the body with reddish golden spots. ... The local name at (Upper) Soda Springs is the Dolly Varden.


It is currently unknown whether the name "Dolly Varden" was later applied to S. m. malma because of its similar appearance to S. confluentus; the two may have even been believed to be the same species. The name "Dolly Varden" may have also been given to S. m. malma independent of the McCloud River fish.

Ironically, it appears that the original "Dolly Varden" trout (i.e., S. confluentus) likely became locally extinct in the McCloud River in the 1970s, although reports continue of its being caught. Other fish species, typically introduced trout, will out-compete S. confluentus, and can interbreed resulting in sterile hybrids. An attempt to re-introduce S. confluentus to the McCloud was unsuccessful, and no additional attempts are expected.
