bt.feyrer.2019.RdThe 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.
bt.feyrer.2019The data frame 2,007 × 11 contains the following columns:
| fish_id | character | fish identifier |
| distance | numeric | distance from the core to the edge of otolith (um) |
| sr8786 | numeric | otolith 87Sr/86Sr (permil) |
| sr8786_norm | numeric | otolith sr8786 norm |
| standar_error | numeric | standar error of sr8786 |
| sr_v | numeric | sr v |
| date | numeric | date of capture |
| lattitude | numeric | lattitude (NAD83) |
| longitude | numeric | longitude (NAD83) |
| length | numeric | fish length (mm) |
| weight | character | body weight (g) |
The dataset includes four seperate files of data for a project that examined the strontium isotopic composition of otoliths of 46 Clear Lake Hitch Lavinia exilicauda chi. 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.
Instrument: LA-MC-ICP-MS (laser ablation–multicollector–inductively coupled plasma–mass spectrometry)
Beam diameter: 40um
Reference materials: NIST-987 (National Institutes of Standards and Technology)
