Abstract
The length frequency/age-length key approach was used in the 2012–13 fishing year to estimate catch-at-age for trevally caught by bottom trawl in TRE 7. There was a high proportion of young trevally but the fishery contained a broad range of fish length and ages, with high estimates of mean length (40.8 cm) and mean age (10.6 years). Spatial differences in length and age compositions were evident between subareas. Spatio-temporal comparisons revealed adequate sample representativeness.
