The base model was used to estimate an annual PST of 26 females. Future fishery deaths at the PST were estimated to result in a mature female population in 2025 that was 3.9% to 5.0% lower than that estimated in the absence of future squid fishery (SQU 6T) deaths; compared with 0.5% to 1.0% lower when future deaths were consistent with deaths estimated for the recent period.
