Pacific Multispecies Small Mesh Bottom Trawl Survey

An OBIS version of Fisheries and Oceans Canada (DFO) Pacific multispecies small mesh bottom trawl survey data from 1953-2024. Survey data are collected by DFO stock assessment staff during annual trawl surveys originally designed with the primary purpose of developing indices of abundance of commercial shrimp species. The survey data have now evolved to monitor trends and document all species encountered. SEE: Dunic, J.C. and Anderson, S.C. 2025.
