Title at head of French summary: Comptes rendus des discussions dans le cadre régional sur la sous-structure du stock de flétan de l’Atlantique, Hippoglossus hippoglossus, des divisions 3NOPs4VWX5Zc de l’Organisation des pêches de l’Atlantique nord-ouest (OPANO) [plateau néo-écossais et sud des Grands Bancs]. Includes bibliographical references. "Atlantic Halibut (Hippoglossus hippoglossus) is a large and long-lived flatfish. It ranges widely in the Northwest Atlantic. In Canada, Atlantic Halibut has been assessed as two regional-scale stocks since 1988, yet the knowledge about its basic ecology is limited. Population structure, migration routes, timing and location of spawning are all unknown. Currently, the management units are the Northwest Atlantic Fisheries Organization (NAFO) Divisions 3NOPs4VWX5Zc (Scotian Shelf and Southern Grand Banks) and NAFO Divisions 4RTS (Gulf of St, Lawrence). The management units were defined by tagging data that showed some Halibut travelled long distances but that mixing between these two areas was low. Recent research investigated Halibut that span the border separating the United States of America (US) and Canada and showed that, from 1965 to 2014, juvenile abundance was, on average, five times greater on the Canadian side of the Hague Line (the nautical international border between US and Canadian waters).”--Summary, p. iv.
