Conditions environnementales dans le sud du golfe du Saint-Laurent en lien avec le crabe des neiges Ottawa : Fisheries and Oceans Canada, 2015. v, 28 p. : fig., graphs, maps, tables. Canadian Science Advisory Secretariat research document, 1919-5044 ; 2015/009, Gulf, Maritimes, Quebec Regions "May 2015." Includes bibliographical references (p. 7-8). The purpose of this research document is to provide information on sea temperature and salinity for the period of 1981 to 2010 in the southern Gulf of St. Lawrence, including snow crab fishing areas (12, 19, 12E and 12F). Information about the amplitude and phase of the bottom temperature seasonal cycle is also provided, as well as areal indices of the ocean bottom covered by summer water temperatures between -1°C and 3°C. The catch of snow crab during the snow crab survey as a function of temperature is presented and yearly changes are documented. The coverage of the snow crab habitat by the polygon used for the estimation of the biomass is investigated. The coverage of a newly introduced polygon for the 2011 snow crab stock assessment is also investigated. The research document begins with a description of the temperature and salinity data, and provides details of the methods used to analyze the temperature fields and finally present the results. gccst Fisheries resources gccst Crustaceans gccst Fishing area gccst Fisheries management Chassé, Joël.
