Age and growth of yellowtail snapper Ocyurus chrysurus from south Florida were determined from otolith cross‐sections. The oldest fish was 14 years old (443‐mm fork length). Mean back‐calculated fork lengths of 807 fish ranged from 136 mm at the end of year 1 to 429 mm at the end of year 14. The von Bertalanffy equation for 802 yellowtail snapper aged 10 or less was L t = 450.9[1 ‐ e −0.279(t+0.355) ], where L = fork length (mm) and t = years. The length‐weight relationship was W = 6.13 × 10 −5 L 2.76 , where W = weight (g).
