There is a much greater biomass of RMWF in streams than Bull trout biomass.

RMWF are sustained by feeding on invertebrates, primarily flies, mayflies, and caddis as identified in the literature.

This is basic food web ecology. Although there will be some positive resource flow from Bull Trout to RMWF, the inverse is much, much more significant.

Something along these lines which might be significant is the conversations longtime flyfisherman have been having about how the hatches on many different rivers have changed drastically. RMWF rely on bugs, and bugs have been changing.

As ive said before...im no scientist....my beliefs and thoughts are purely untrained field observations....I respect many of you have far more trained tech reasoning.
