Purpose

In this study, we used stable isotope values of eye lenses to provide complimentary information on habitat utilization by a threatened cyprinid, Clear Lake Hitch (Lavinia exilicauda chi). Clear Lake Hitch inhabit a single lake (Clear Lake, Lake County, California) and utilize tributary streams for reproduction. Despite recent advances, there remain key uncertainties about Clear Lake Hitch habitat use. Analysis of δ13C and δ15N recorded in eye lenses demonstrates ontogenetic diet shifts that corresponded with shifts in habitat. Reconstruction of size-structured trophic and habitat information provides critical information to resource managers.
