Significant outputs from the analysis are re-analysed 1997–2019 time series for survey (May) and season (September) biomass, derived by applying a new dredge efficiency curve and conducting projections using an inverse logistic growth model. The recruited biomass estimate for 2019 within the area surveyed is the lowest on record, and recruitment in the short-term is likely to be poor.
