Download FAR 2023/59 Further development of models for arrow squid in New Zealand waters

This report summarises population models for arrow squid in the Subantarctic. The models captured the main biological processes adequately. Recruitment estimates were robust to model assumptions and structure. However, absolute estimates of biomass were highly uncertain. The potential for in-season management was tested. Proxies that could be used to compare current relative exploitation rates with past conditions were also investigated; these could be used for hindcasting.
