The fishery was dominated by young to moderate aged snapper 3–10 years (90% by number landed). Mean age (6.9 years) was the highest recorded estimate in 27 years suggesting further improvement to the status of the fishery, despite a continued slowing in growth rate. Spatio-temporal comparisons revealed adequate sample representativeness.
