The report provides a summary of recent trends in the catch, catch rate and length composition of gemfish from the SKI 3 and SKI 7 commercial fisheries and relevant trawl surveys. Standardised CPUE indices were derived from the gemfish bycatch from west coast South Island hoki fishery. An age structured population model was configured for the southern gemfish stock. The model provides a framework for evaluating the trends in abundance indices and composition data. The report provides recommendations for further development of the model to attain a more comprehensive assessment of stock status.
