All available information on the biology, assessment, fishery and management of Grand Bank yellowtail flounder stock, Division 3LNO, is drawn together to assess the status of the stock in 2002. Recent surveys by Canada and Spain indicate that stock size has been increasing since a moratorium on directed fishing was declared in 1994. A surplus production model, incorporating current and historical survey and catch indices, was used to assess relative biomass, fishing mortality rates and to provide short and medium term yield projections. Results are presented in a precautionary approach framework.
