Methods and summary data from the Northumberland Strait multi-species bottom trawl survey, 1999 to 2018 / by Natalie C. Asselin, J. Mark Hanson, Daniel Ricard and Amélie Rondeau. : Fs97-6/3432E-PDF
"In 1999, Fisheries and Oceans Canada initiated a bottom trawl survey in Northumberland Strait in the southern Gulf of St. Lawrence. The primary survey objective was to collect data to assess the status of the southern Gulf of St. Lawrence lobster stock. Conducted annually from 1999 to 2018, the survey objectives, the sampling methods, the survey vessel and the study area changed over the years. Beginning in 2005, data were systematically collected for lobster, crab and fish. The survey vessel also served as a platform from which to collect oceanographic data [e.g. Conductivity, Temperature and Depth (CTD) and water samples]. The relative densities and length frequencies of the most commonly captured crustacean and fish species (or species groups) are presented. Future work includes quantifying the swept area of the sampling sets to allow for more robust analyses of temporal changes in abundance and distribution"--Abstract.
