The red rock lobster (Jasus edwardsii) supports the most valuable inshore commercial fishery in New Zealand. This fishery has been managed with catch quotas in nine Quota Management Areas (QMAs), which are usually treated as independent populations or stocks.
This document describes a stock assessment of red rock lobster in CRA 4 up to the 2023–24 fishing year. This stock assessment suggests that CRA 4 has experienced periods of biomass peaks and troughs over the time series modelled and has been increasing towards a peak for the past decade. This pattern has likely been driven by variability in recruitment and catch rates. Projections suggest the stock may hit a peak in biomass over the next five years.
