Abstract
The length frequency/age-length key approach was used in spring/summer 2012–13 to estimate catch-at-age for snapper caught by bottom trawl in SNA 8. Although largely dominated by young snapper (93% of the landed catch by number < 11 years old), mean age (6.4 years) was the second highest seen for two decades suggesting some improvement to the status of the fishery, despite indications that growth rates have recently slowed. Spatio-temporal comparisons revealed adequate sample representativeness.
