Bringing in the experts: application of industry knowledge to advance catch rate standardization for northern shortfin squid (Illex illecebrosus)

Sources of fisheries information outside fishery-independent surveys (e.g. fishery-dependent data) are especially valuable for species that support productive and lack reliable biological information, such as the northern shortfin squid ( Illex illecebrosus ). Fishery-dependent data streams available most species, however collaboration with industry members is critical to ensure these collected, applied, interpreted correctly. Despite need frequency fishery used in scientific research, there limited literature on structure interactions knowledge sharing inform analysis application data. Between 2019 2022, a group researchers collaborated fishing bring together research sets from harvesters processors better describe dynamics, distribution, life history, oceanographic drivers species. The focused developing custom standardized catch per unit effort (CPUE) indices provide indicators population trends accounted impacts technical economic aspects harvesting, processing marketing effort, selectivity landings squid. We methods interpret CPUE analyses, focusing novel we had members, suggest best practices integrating into standardization. shared products produced through this science-industry advanced understanding contributed directly 2022 stock assessment management process.
