Size-age composition of southern poutassou (Micromesistius australis) catches in New Zealand area
Length-age composition of catches of the Southern blue whiting (Micromesistius australis) in the New Zealand waters were studied. The material was collected from August to October 1992 aboard the FV Sapun Gora (19th cruise). A total of 398 pairs of otoliths were treated. Ten age groups were distinguished. The maximum fish age in catches is 13 years. 10- and 11-year-old fish are absent from the samples. No significant difference is found in the growth of males and females. Males at any age are somewhat smaller than females. It was ascertained that the linear growth of the Southern blue whiting from the region of New Zealang was described by the Von Bertalanffy's growth equation as follows: L = 61.41(1-e super(-0.3659(1-0.6336))).
