The general objective was to determine by market sampling the age structure of cornmercial landings from the three snapper stocks that constitute SNA 1 for use in stock assessment models. The random age frequency sampling approach was employed over four seasons from spring 2004 to winter 2005 to estimate catch-at-age for snapper from the three bottom longline fisheries in SNA 1; Bay of Plenty, Hauraki Gulf, and East Northland. Target sample sizes were achieved from all the fisheries sampled.
