[3] The McCloud River hatchery indiscriminately mixed coastal rainbow trout (O. m. irideus) eggs with the eggs of local McCloud River redband trout (O. m. stonei).

Eggs from the McCloud hatchery were also provided to the San Leandro hatchery, thus making the origin and genetic history of hatchery-bred rainbow trout somewhat diverse and complex.

134) from anatomical characteristics "...stonei would be useful only as name for the trout of a particular geographical region (upper Sacramento River Basin), not as a natural evolutionary unit.

[6] The type material of stonei is similar to redband trout of the Pit River and Goose Lake while McCloud River redband trout are clearly differentiated anatomically from the type material of stonei.

[5][7] The taxon O. m. calisulat Campbell and Conway 2023 was created to apply to the native redband trout of the upper McCloud River.
