Évaluation des niveaux de prises accessoires de morue franche (Gadus morhua) dans les pêches du homard (Homarus americanus) des divisions 4X5Y de l'OPANO

Abstract

Resource Management requested information on the level of bycatch of Atlantic Cod in Lobster fisheries in the Northwest Atlantic Fisheries Organization (NAFO) Divisions 4X5Y stock area. Data from multiple sources were used to estimate Cod bycatch, including scientific surveys, at-sea sampling programs, and environmental data collected in NAFO Divisions 4X5Y. Evaluation of multiple candidate models determined the spatial model to be the best model for prediction of annual total Cod bycatch in the Lobster fishery. Predicted annual total bycatch of Cod in the Lobster fishery within NAFO Divisions 4X5Y ranged between 461–1,066 metric tons for years 2018–2023. Uncertainty of predicted totals can be high due to gaps in interannual and regional sampling coverage.
