By Bourdages, H., Marquis, M.C., Ouellette-Plante, J., Chabot, D., Galbraith, P., and Isabel, L.

Abstract

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 2019 and the indicators from the survey from 1990 to 2019. In addition, this document describes how some of the environmental and ecosystem characteristics of the Gulf of St. Lawrence potentially impact the northern shrimp stock dynamic through their effects on such factors as spatial distribution, growth, reproduction and trophic relationships.
