“…Fish undergoing catch-up growth during period 2 had a shortened adult lifespan, while those showing a slow-down in growth over the same period had an extended lifespan. Although it has previously been documented that the longevity of ectotherms can be extended if they are continually kept at cooler temperatures [19][20][21][22], presumably because of temperature effects on cellular processes as mentioned above, this study is, to our knowledge, the first to report that brief exposures (equivalent to less than 4% of median lifespan) to episodes of atypical temperatures have important long-term effects on longevity.…”

The hypothesized negative relationship between growth rate and lifespan has proved very difficult to test robustly because of potentially confounding variables, particularly nutrient availability and final size. Here we provide, to our knowledge, the first rigorous experimental test of this hypothesis, and find dramatic changes in lifespan in the predicted direction in response to both upward and downward manipulations of growth rates. We used brief (less than 4% of median lifespan) exposure to relatively cold or warm temperatures early in life to deflect juvenile three-spined sticklebacks Gasterosteus aculeatus from their normal growth trajectories; this induced catch-up or slowed-down growth when ambient temperatures were restored, and all groups attained the same average adult size. Catch-up growth led to a reduction in median lifespan of 14.5 per cent, while slowed-down growth extended lifespan by 30.6 per cent. These lifespan effects were independent of eventual size attained or reproductive investment in adult life. Photoperiod manipulations showed that the effects of compensatory growth on lifespan were also influenced by time available for growth prior to breeding, being more extreme when less time was available. These results demonstrate the growth-lifespan trade-off. While growing more slowly can increase longevity, the optimal resolution of the growth-lifespan trade-off is influenced by time constraints in a seasonal environment.

“…Gonadal maturation in the ocean quahog is slow and first spawning occurs between 10 and 14 yr of age (Thompson et al 1980b). Furthermore, there is a general trend observable in aquatic ectotherms towards increased maximum life spans in the cold when comparing temperate and cold water species of similar lifestyle (Brey 1991, Brey et al 1995, Ziuganov et al 2000, Cailliet et al 2001, La Mesa & Vacchi 2001, and deferred maturation and late reproductive output may form part of this life extension in cold water. This also implies a delay in physiological ageing in the cold.…”

The ocean quahog Arctica islandica is one of the longest-living and slowest-growing marine bivalves. The oldest specimens obtained for the present study approached 200 yr. To achieve such a long lifespan, accumulation of oxidative damage markers in tissues must ideally be maintained at low levels over time, because the accumulating debris disturbs cellular functions. We investigated shell growth and cellular aging in an Icelandic population of A. islandica. Specifically, we analyzed protein carbonyl concentration as a marker for the oxidative deterioration of tissue proteins, and the accumulation of the fluorescent age pigment lipofuscin over quahog lifetime in gill, mantle and adductor muscle. The very slow growth rates of A. islandica correlate with very efficient maintenance of body proteins compared to other, faster aging bivalves. Lipofuscin granules accumulated mainly in connective tissues of gill and mantle. Lowest lipofuscin accumulation was found in the adductor muscle, and there, only outside the myofibrils. Consistent with the pleiotropic theory of aging, A. islandica seems to trade slow growth and late onset of reproduction for a very efficient autophagic potential that mitigates oxidative damage accumulation and supports long lifetime and presumably reproduction in very old ocean quahog.

“…chronological values across the otolith that are not dissimilar to the deepwater bluenose curve of Horn et al 2010) support the maximum age of c. 100 years from otolith zone counts. This remains a surprisingly high age, but the oxygen isotope results do suggest that the oldest fish reach depths of 800Á1000 m, and such deepwater species are often found to be long-lived (Cailliet et al 2001). The likely progression of some strong year classes through the three commercial fishery age distributions provides some additional validation of the method used to age rubyfish.…”

Age verification of rubyfish (Plagiogeneion rubiginosum) was sought using the bomb radiocarbon chronometer procedure. Stable isotopes were investigated for life history characteristics. Radiocarbon ( 14 C) and stable isotope (d 18 O and d 13 C) levels were measured in micro-samples from five otoliths that had been aged using a zone count method. All the core 14 C measurements were 'pre-bomb' indicating ages of at least 45 years, and the 14 C measurements across the otolith sections suggested that the zone-count ageing method described herein is not biased. Maximum estimated age was 100 years. There was no significant between-sex difference in the von Bertalanffy growth curves. The d 18O values indicated that rubyfish are near-surface as juveniles, and move deeper with age. Adults appear to reside in 600Á1000 m; this is deeper than most trawlcapture data suggest, but not implausible, and has stock assessment implications. The d 13 C values reflect fish metabolic rates, trophic feeding levels and oceanographic conditions. The stable isotopes record the environmental life history of each fish, and have value in distinguishing stocks and/or indicating vertical and latitudinal migratory patterns.
