Spatial Stock Assessment Models

Research Summary

Mark and his collaborators have been involved in a variety of projects developing spatial stock assessment models. Mark, in parallel with Dave Fournier and colleagues, pioneered the integration of tagging data into integrated spatial stock assessment models in his PhD dissertation (Maunder 1998; 2001). In 2018 he co-organized and chaired the CAPAM workshop on Spatial stock assessment models and acted as a guest editor for the Fisheries Research special issue (Cadrin et al. 2020). Mark has been involved in developing several spatially structured population dynamics and stock assessment models (e.g. Aires-da-Silva et al. 2009).  Mark and his colleagues reviewed the use of electronic tags in fisheries stock assessment (Sippel et al., 2015).

Mark and his colleagues investigated the areas as fleets approach to approximate spatial structure and movement finding that movement caused areas as fleets selectivity curves to be dome shaped and time varying (Waterhouse et al. 2014). They have also investigated alternative approaches to use selectivity curves to approximate movement in bluefin tuna (Lee et al. 2017).

All of the spatial-temporal models developed by Mark and his colleagues can be used to evaluate catch, CPUE, and composition data to input into spatially structured stock assessments (e.g. Satoh et al. 2021; Maunder et al., 2021, Xu et al., 2019).
