Abstract
This report describes the results of blue cod (Parapercis colias) fixed- and random-site potting surveys carried out concurrently in Marlborough Sounds in September/October 2013. Estimates are provided for population abundance, size and age structure, sex ratio, total mortality (Z), and spawner-per-recruit ratio. This is the seventh survey in the fixed-site survey time series that began in 1995, and the first full random-site survey.
