Download FAR 2022/22 A stock assessment of red gurnard in GUR 7 for 2022

A stock assessment was developed for GUR 7 integrating annual catches and Kaharoa WCSI trawl survey biomass indices and associated length and age compositions. The assessment model estimated that stock abundance increased considerably from 2010 following higher levels of recruitment during 2008–2019. For all model options, current (2021) stock status was estimated to be at about the equilibrium, unexploited biomass level (i.e., SB0). A range of potential management procedures were evaluated.
