Abstract
The length frequency and age-length key sampling approach was employed during 2012–13 fishing year to estimate catch-at-age for trevally for the bottom trawl and purse-seine methods in TRE 1. Spatial differences in length and age compositions and growth rates persist between the East Northland/Hauraki Gulf and Bay of Plenty subareas, implying the existence of multiple biological stocks. Spatio-temporal comparisons revealed good sample representativeness.
