Assessment of the southern Gulf of St. Lawrence Atlantic Cod (Gadus morhua) stock of NAFO Div. 4T and 4Vn (November to April), March 2019 / Douglas P. Swain, Daniel Ricard, Nicolas Rolland, and Éliane... : Fs70-5/2019-038E-PDF
"This report describes the fisheries for the sGSL cod stock for 2015 to 2018 and provides an assessment of stock status to Jan. 1, 2019 based on research, sentinel and fishery data available to the end of 2018. A population model is fit to these data to provide estimates of population size and rates of fishing and natural mortality. Projections of population biomass over the 2019 to 2023 period are also provided, along with estimates of the uncertainty in these projections. An ecosystem approach is taken to identify causes of the changes in productivity of this stock and to evaluate options for reversing its ongoing decline"--Introduction, page 2.
