Stock assessment of witch flounder (Glyptocephalus cynoglossus) in the Gulf of St. Lawrence (NAFO divs. 4RST) to 2016: Fs70-6/2017-036E-PDF

"The commercial fisheries for Witch Flounder (Glyptocephalus cynoglossus) in the northern Gulf of St. Lawrence (NAFO Divisions 4RS) came under quota management in 1977, with a quota of 3,500 t. In 1979, the Total Allowable Catch (TAC) in NAFO Divs. 4RS was increased to 5,000 t to remove an old and slow-growing component of the stock. This measure succeeded in reducing the age composition of the stock; however, landings declined and by 1982, the TAC was reduced to 3,500 t. During the 1980s, landings from NAFO Div. 4T increasingly dominated the Gulf of St. Lawrence Witch Flounder landings. The first detailed assessment of NAFO Divs. 4RS Witch Flounder was conducted in 1978 and continued yearly until 1981. When stock assessments resumed in 1991 and following the recommendation of the Fisheries Resource Conservation Council in 1994, the management unit was extended to NAFO Divs. 4RST in 1995. The last full assessment of this stock occurred in 2012. This Science Advisory Report is from the March 2, 2017 science peer review meeting on the stock status and fishery advice for May 2017 to May 2022 for Witch Flounder from NAFO Divisions 4RST, Gulf of St. Lawrence. Participants at the meeting included DFO Science (Gulf, Newfoundland and Labrador regions), DFO Fisheries Management (Gulf, Newfoundland and Labrador regions), and the fishing industry and a non-governmental organization"--Context, p.
