Natal origin of Pacific bluefin tuna Thunnus

In this study, high-resolution stable oxygen isotope (δ18O) analysis was performed on the otoliths of adult Pacific bluefin tuna Thunnus orientalis using secondary ion mass spectrometry (SIMS) to determine the natal origin of an individual fish.

Format

The data frame 676 × 7 contains the following columns:

fish_id	character	fish identifier
distance	numeric	distance from the otolith core (um)
d18o	numeric	oxygen isotope ratio relative to VPDB in permil
catch_location	character	location of capture
year_class	integer	year of hach
weight	numeric	body weight (kg)

Details

Summary on sampling data, biological information, and d18O otolith analyses of 51 Pacific bluefin tuna otoliths.

Instrument: SIMS (secondary ion mass spectrometer)

Beam diameter: 10um
