Download FAR 2022/06 Characterisation and CPUE from 1989–90 to 2018–19 of jack mackerel off the west coast of New Zealand (JMA 7)

This document includes a descriptive analysis of available data and literature to determine the species and stock structure of jack mackerel in JMA 7 and attempts to develop a species-specific CPUE series for JMD and JMN in JMA 7. However, the descriptive analysis uncovered several issues that were deemed serious enough to prevent the development of reliable CPUE series by species. Despite this setback, a set of combined species (JMD, JMM, and JMN) CPUE indices are provided.
