To understand Fallen Leaf Lake food web interactions between nonnative species that prey on or compete with reintroduced LCT a combination of stomach content and stable isotope analyses was used to evaluate trophic characteristics within the aquatic species assemblage. LCT preyed on a variety of prey resources: mysid shrimp, insects, arthropods, signal crayfish and fishes. Diet overlap was greatest between L CT and Mountain Whitefish and both species exhibit a general feeding strategy that allows them to partition prey resources to avoid competitive interactions. Predation by Lake and Brown Tout on stocked LCT was observed and should be considered in the context of predator management.

Threshold Categories
-
The results of this study contributed to management and recovery actions that were needed to restore and improve both lake and stream habitats for the Federally listed Lahontan cutthroat trout.
-
The stocking efforts undertaken for this study also contributed to restoring a near-shore native fishery at Fallen Leaf Lake.
