Results demonstrate that Hoplostethus atlanticus from the north-east Atlantic Ocean have a complex life history with three distinct depth-stratified life stages, and lifetime fastest growth rates are achieved during juvenile stages when otolith isotopes imply deep-water residency and relatively low metabolic rates.

The data frame 88 × 6 contains the following columns:
fish_id | character | fish identifier |
body_mass | numeric | reconstructed mass (g) |
distance | numeric | distance from otolith centre (mm) |
d18o | numeric | oxgen isotope ratio |
d13c | numeric | carbon isotope ratio |
temperature | numeric | reconstructed temperature (°C) |
This dataset contains stable-isotope compositions recorded in otoliths from Hoplostethus atlanticus, together with body mass reconstructed using equations (3 and 4), and ambient water temperature recovered using estimated water δ18O values (provided) and equation (6).
Instrument: LA-ICP-MS (laser ablation-inductively coupled plasma mass spectrometry)
