Cover title. “May 2017.” Includes bibliographical references (p. 13-15). “Redfish fishing in the Gulf of St. Lawrence (Unit 1) targets two species, Sebastes mentella and S. fasciatus. Between the mid-1950s and 1993, it was marked by three more intense exploitation episodes that were closely linked to recruitment of one or several strong year-classes. A sudden drop in landings and the absence of recruitment led to the imposition of a moratorium in 1995. Redfish fishing is still under a moratorium in Unit 1 and an index fishery has been authorized there since 1998. Total allowable catches have been 2,000 t per year since 2006. According to the reference points of the precautionary approach of 2011, both stocks have improved. However, the mature biomasses are still in the critical zone and this fact should not change over the course of the next three years. In support of the redfish stock assessment survey (S. fasciatus and S. mentella) of Units 1 and 2 in 2015, this document describes the data and methods use for the stocks of Unit 1 under the responsibility of the Science Branch, Quebec Region of the Department of Fisheries and Oceans"--Abstract, p. viii.
