In this study, the authors used Sr isotopic markers recorded in otoliths of wild and farmed commercialized pirarucu (Arapaima spp.) to evaluate their prediction potential to trace the fishes origin.

The data frame 4,148 × 5 contains the following columns:
specimen_code | character | specimen id |
distance | integer | distance from fish otolith cores – edge transects (unit: micron) |
oto_sr8786 | numeric | variation of 87Sr/86Sr measured by LAfs-MC-ICPMS |
fish_origin | character | wild fish and farmed fish |
region | character | region of captured |
The dataset contains wild and farmed commercialized pirarucu (Arapaima spp.) otolith strontium isotope profiles. Variation of 87Sr/86Sr values measured by LAfs-MC-ICPMS on wild fish otolith cores – edge transects.
Wild fish specimens that lived in environments with the largest fluctuation of river water Sr isotope ratios over time presented the largest Sr isotope variations in otoliths.
Instrument: fs-LA-MC-ICP-MS (femtosecond laser ablation multi-collector inductively coupled plasma mass spectrometer)
Scan speed: 5um/s
