Assessment of northern shrimp stocks in the Estuary and Gulf of St. Lawrence in 2021: commercial fishery and research survey data

By Bourdages, H. Roux, M.-J., Marquis, M.C., Galbraith, P., and Isabel, L.


The Estuary and Gulf of St. Lawrence northern shrimp (Pandalus borealis) stock status is determined every year by examining many indicators from the commercial fishery and the research survey. This document presents the data and methods that were used to produce the commercial fishery statistics from 1982 to 2021 and the indicators from the survey from 1990 to 2021. In addition, the document presents some ecosystem characteristics observed in the estuary and the northern Gulf of St. Lawrence. These can have an impact on the dynamics of northern shrimp stocks through, among other things, effects on spatial distribution, growth, reproduction and trophic relationships. The elements of the precautionary approach are also presented in this document.
