Age determination for Diagramma pictum, (n=102), were conducted using three methods. The two first methods are based on the counts of annuli on respectively whole otolith cross sections. The third method use the decrease of otolith daily growth increment (DGI) density with age. The growth curves found with the first two methods are comparable and similar to previous results. However, the analysis of life history traits such as size at first reproduction indicates that these methods are likely to underestimate growth. The use of DGI density yields a faster growth curve. To establish this curve the relationships liking fish size to otolith radius and DGI density to otolith radius are needed. The final growth curve is particularly sensitive to changes in these previous relationships. For this reason all sizes should be well represented in the sample. This method is not recommended for fish with large seasonal growth variations but could produce good DGI measurements for those species which have only a small zone of readible otolith.
