The Clear Lake Hitch is a subspecies of a California native minnow that only exists in Clear Lake in Lake County. The species was recently listed under the California Endangered Species Act as Threatened. A multiagency Conservation Strategy Team was formed to determine potential actions that could help recover the species and potentially lead to a delisting. One of the first actions proposed by the team was to get an accurate baseline population estimate so they could determine if restoration and other recovery activities are making an improvement at the population level. Starting in March and proceeding weekly until the end of May, CDFW fisheries scientists will be performing a mark recapture study on Clear Lake using electrofishing boats to capture Clear Lake Hitch. Once captured, the fish are marked with a fin clip, then released. A second effort (recapture) will take place several weeks later. The scientists will then use a mathematical model to compare the number of previously captured marked fish to the number of newly captured unmarked fish, in order to estimate the total Clear Lake Hitch population.
