Feyrer, F.V., 2018, Clear Lake Hitch Otolith Data: U.S. Geological Survey data release,


The dataset includes four seperate files of data for a project that examined the strontium isotopic composition of otoliths of Clear Lake Hitch. Otoliths examined in this study were from randomly-sampled individual Clear Lake Hitch that recruited into the adult population in Clear Lake. The fish were collected in June and July 2017. Strontium isotopic composition (87Sr/86Sr ) in otoliths was determined with a multicollector LA-ICP mass spectrometer (LA-ICMPS; Nu Plasma HR, Nu Instrument, Inc.) interfaced with a Nd : YAG 213-nm laser (New Wave Research UP213) at the University of California, Davis. Fish capture and size data are in the file Clear Lake Hitch Otolith Data_FISH. Otolith increment data are in the file Clear Lake Hitch Otolith [...]

The goal of this study was to determine if otolith chemistry could be used to reconstruct the habitats occupied by individual Clear Lake Hitch. Study objectives included determining the relative importance of natal habitats and early life migration histories that have contributed to the production and adult recruitment of Clear Lake Hitch. The data will be reported in: Feyrer, F., Whitman G., Young M., Johnson, R. 2018. Strontium isotopes reveal the role of ephemeral streams to the early life migration and recruitment success of an imperiled potamodromous cyprinid. Marine and Freshwater Research. (in review)
