New Zealand fisheries assessment reportSummary: This study was contracted as MFish project SNA2008/01 with the specific objective: To characterise the SNA 8 fishery and update the CPUE analyses for trawl fisheries in each area of SNA 8 using data up to the end of 2007-08. The stock assessments for snapper rely mainly on absolute abundance estimates from tagging programmes. Absolute abundance of SNA 8 was last estimated in 2002 and the next mark-recapture study is scheduled for 2011. Standardised CPUE series, updated every three years, are used to provide crude indices of relative abundance in the periods between tagging programmes. The SNA 8 CPUE index was last updated to the end of the 2003-04 fishing year (MFish project SNA 2004-01) and indicated a declining trajectory to 2000-01 followed by a recovery in the subsequent three years.
