Includes bibliographical references. "Fisheries and Oceans Canada (DFO) undertook in 2021 and 2022 a review of the assessment framework for Atlantic cod (Gadus morhua) in NAFO 3Pn4RS (hereafter northern Gulf of St. Lawrence, nGSL, cod). This review, which will take place in two parts, will evaluate appropriateness and utility of a new assessment model for the stock and existing and new inputs to that model. The present document evaluates the information, data and indices that are available from fishery independent surveys and that can contribute to the renewed assessment. This includes data and results from historical surveys that have not been used to assess the stock for more than two decades. Three classes of surveys are examined: research vessel (RV) bottom-trawl surveys, Sentinel bottom-trawl surveys and Sentinel fixed-gear surveys undertaken using gillnets and longlines. These are presented in turn in separate sections. For each of these classes of surveys we provide revised or new indices of abundance or status"--Introduction, page 1.
