Southern blue whiting, New Zealand southern blue whiting
Besides being found around the southern tip of South America, Southern blue whiting (Micromesistius australis) is found on the southern shelf of New Zealand, but is occasionally considered to be a distinct subspecies – Micromesistius australis pallidus, as opposed to Micromesistius australis australis.
Hanchet (1999) found significant differences in growth rates as well as on morphometric characteristics suggesting that the 4 stocks, which present distinct spawning grounds, should be assessed and managed separately: Auckland Islands (SBW 6A), Bounty Platform (SBW 6B), Campbell Island Rise (SBW 6I) and Pukaki Rise stock (SBW 6R). These 4 biological stocks are used by the Ministry for Primary Industries (MPI) for assessment and management purposes (Fisheries New Zealand 2019).
