A time‐resolved record of inhabited water depth, metabolic rate and trophic behaviour of the orange roughyHoplostethus atlanticuswas recovered from combined stable‐isotope analyses of otolith and muscle tissue. The results demonstrate thatH. atlanticusfrom the north‐east Atlantic Ocean have a complex life history with three distinct depth‐stratified life stages. Early juvenileH. atlanticusoccupy relatively shallow habitats, juvenileH. atlanticusshow a deep‐demersal phase, rising at sexual maturity, and adultH. atlanticusexploit increasingly deep habitats with increasing age. At all sampled sizes,H. atlanticusmuscle tissues have an isotopic composition suggesting a benthic rather than benthopelagic or pelagic diet. Isotopic measures of relative metabolic rate provide an insight into energy partitioning throughout ontogeny.Hoplostethus atlanticushave relatively low metabolic rates compared to coexisting deep‐water benthic fishes, consistent with their unusually high longevity. Surprisingly, lifetime fastest growth rates are achieved during juvenile stages when otolith isotopes imply deep‐water residency and relatively low metabolic rates. Fast growth may be sustained during a period of high efficiency associated with reduced metabolic costs of prey capture or predator evasion. The stable‐isotope approach can be applied to any teleost and provides a rapid, cost‐effective technique for studying deep‐water fish communities.
