These tiny native fishes represents the largest biomass in the creek.
Rarely seen, they are cryptic and hide out under rocks.
This is Cujo, a native Lahontan Cutthroat trout raised in the Forest Service office aquarium and released into Sagehen Creek.
The native LCTs were extirpated from Sagehen Creek by the introduction of Brook, Brown and Rainbow Trout.
We are studying these fish with an eye toward eventual reintroduction.
