Scales and otoliths were used to determine age of vermilion snapper, but only scales were used to back-calculate lengths. Scale annulae are laid down in March-April and their formation is well correlated with increasing photoperiod, preparation for spawning, and rising bottom water temperature. The von Bertalanffy growth equation fitted to back-calculated lengths (L, mm total length; t, years) is: Lt= 626.5 [1 - e-0.198(t-0.198)]. Maximum longevity of females is at least 10 years but males may only live 8 years. The length-weight (W, g) relationship (r = 0.97) is: W = 0.00001722 L2.946.
