Description
Summary:Since 1971 the Northwest Atlantic Fisheries Centre, Department of Fisheries and Oceans, St. John's, Newfoundland, has conducted stratified random surveys off Canada's northeast coast using four different fisheries research vessels; A. T. Cameron, Gadus Atlantica, Wilfred Templeman and Teleost. Each vessel used it's own unique survey trawl. Left unregulated, these "standardized " survey trawls were found to have changed in construction and rigging over time. A technical description and the chronology of each survey trawl used by these research vessels is discussed along with procedures adopted to ensure the complete standardization of the survey trawl within a research vessel and across the fleet.
