- In the Estuary and Gulf of St. Lawrence, four assessment units have been used since 1993 for the assessment of northern shrimp stocks, namely the Estuary, Sept-Iles, Anticosti and Esquiman areas. These stock assessment units correspond to locations where high concentrations of shrimp are generally observed during the research survey. Information on northern shrimp abundance and the distribution of fishing effort over the last several decades suggests that the stock assessment units in the Estuary and northern Gulf of St. Lawrence need to be changed. A new delineation of the stock assessment units is proposed and supported by findings from a population genomics study. The stock indicators have been updated based on the new delineation, which provides an improved correspondence between assessment units and biological units.

- Dans l’estuaire et le golfe du Saint-Laurent, quatre unités d’évaluation sont considérées depuis 1993 pour l’évaluation des stocks de crevette nordique, soit Estuaire, Sept-Îles, Anticosti et Esquiman. Ces unités d’évaluation des stocks correspondent aux endroits où des concentrations élevées de crevette sont généralement observées pendant le relevé de recherche. Des informations sur l’abondance et la distribution de l’effort de pêche à la crevette nordique des dernières décennies suggèrent qu’une modification des unités d’évaluation des stocks dans l’estuaire et le nord du golfe du Saint-Laurent est nécessaire. Un changement des délimitations des unités d’évaluation des stocks est proposé et appuyé par la génomique des populations. Les indicateurs de ces stocks ont été mis à jour en fonction des unités d’évaluation proposées et représentent une meilleure adéquation entre les unités d’évaluation et les unités biologiques.
