 Catch (in number of fish) and effort (CPUE) of juvenile albacore (Thunnus alalunga) in the New Zealand troll fishery are reported by fishers and the catch rates are standardised for shifts in the fleet and fisher behaviour to identify any underlying trends in abundance that may inform the stock assessment. The conclusion of this study is that CPUE of troll-caught albacore in New Zealand waters is unlikely to be a useful index of abundance. There is probably no recruitment signal in these indices.
