	abstract = {A previous study that explored the age and growth of red steenbras Petrus rupestris (Valenciennes, 1830), a large sparid (family Sparidae, seabreams or porgies) endemic to South Africa and reported to approach 2 m in length, provided estimates as a moderately slow-growing species with a maximum age near 30 years. The stock is considered collapsed and a fishing moratorium was imposed in 2012, resulting in this species being assessed as Endangered by the IUCN. One consideration in addressing population status is validation of life-history traits. In this study, estimates of age for red steenbras from thin-sectioned otoliths were reassessed visually in terms of both the original ages and revised estimates using a different age-reading pattern. The revised ages exceeded the original ages by up to 30 years, with a maximum estimated age of 55 years from a well-defined otolith section that provided a basis for the revised age-reading procedure. Bomb radiocarbon (14C) dating revealed there was an offset in the timing of the 14C rise on the Agulhas Bank that, when coupled with considerations for regional oceanography, provided support for the revised age-reading pattern and an estimated longevity that exceeds 50 years. These findings were further supported by the fortuitous recapture of a tagged red steenbras that was at liberty for 22 years.},

	abstract = {Radiocarbon (D14C) was analyzed in northern Gulf of Mexico (nGOM) red snapper (Lutjanus campechanus) otolith cores (n{\textonequarter}23), otolith
edge samples (n{\textonequarter}12), and whole age-0 otoliths (n{\textonequarter}9), with edge samples and whole age-0 otoliths constituting known-age samples.
There was no significant difference in the linear relationship of D14C versus year of formation between regional corals and known-age otolith
samples, and a linear regression fit to the combined data from 1980 to 2015 extends the utility of the bomb radiocarbon chronometer
for age validation. The entire regional coral and known-age otolith data set (1940 to 2015) was then utilized as a reference series to validate
otolith-derived red snapper age estimates for cored otolith samples. A loess regression was fit to the reference data and then the sum
of squared residuals (SSR) was computed from predicted versus observed birth years for cored adult otolith samples. This process was
then repeated for ages biased 61{\textendash}4 years. Ages with no bias applied had the lowest SSR, thus validating red snapper age estimates and
demonstrating the utility of the combined regional coral and known-age red snapper otolith D14C time series for age validation of nGOM
marine fishes.},

	abstract = {We used bomb radiocarbon (C-14) in this age validation study of Dover sole (Microstomus pacificus). The otoliths of Dover sole, a commercially important fish in the North Pacific, are difficult to age and ages derived from the current break-and-burn method were not previously validated. The otoliths used in this study were chosen on the basis of estimated birth year and for the ease of interpreting growth zone patterns. Otolith cores, material representing years 0 through 3, were isolated and analyzed for C-14. Additionally, a small number of otoliths with difficult-to-interpret growth patterns were analyzed for C-14 to help determine age interpretation. The measured Dover sole C-14 values in easier-to-interpret otoliths were compared with a C-14. reference chronology for Pacific halibut (Hippoglossus stenolepis) in the North Pacific, We used an objective statistical analysis where sums of squared residuals between otolith C-14 values of Dover sole and the reference chronology were examined. Our statistical analysis also included a procedure where the Dover sole C-14 values were standardized to the reference chronology. These procedures allowed an evaluation of aging error. The C-14 results indicated that the Dover sole age estimates from the easier-to-interpret otoliths with the break-and-burn method are accurate. This study validated Dover sole ages from 8 to 47 years.},
