Download FAR 2021/78 Characterisation, catch-per-unit-effort, and stock assessment of packhorse rock lobsters (Sagmariasus verreauxi) in New Zealand

This research characterised the catch and biological data from the New Zealand packhorse rock lobster fishery. In addition, a biomass dynamics stock assessment model was developed based on estimates of historical catch and CPUE. This model suggested a stock that was initially heavily fished to a low level in the 1980s, then increased rapidly during the 1990s, and has plateaued at levels well above BMSY since the mid-2000s.
