This report describes results from the random-site blue cod potting survey off north Otago in January 2022. Estimates are provided for population relative abundance, size and age structure, sex ratio, total mortality (Z), and fishing mortality (F). This was the third survey in the random-site survey time series with previous surveys in 2013 and 2018. In addition, 4 random sites were sampled in the proposed marine reserve (Te Umu Koau, D1) that, in part, overlaps with the main survey strata.
