Update of the 2008 Summer Scotian Shelf and Bay of Fundy Research Vessel Survey
By D. Clark and J. Emberley
Abstract
The 2008 Scotian Shelf summer Research Vessel (RV) survey was conducted between 5 July and 1 August 2008, onboard the CCGS Wilfred Templeman. The Wilfred Templeman made 97 fishing sets during the first leg of the survey and 82 during the second leg. In Northwest Atlantic Fisheries Organization (NAFO) Divisions 4X5Y (strata 470-495), 75 valid tows were completed, while 90 valid tows were completed in NAFO Divisions 4VW, (strata 440-466), and 5 sets were completed in strata 496-498 (Scotian Shelf edge; depth greater than 200 fm). Hydrographic data were collected at all fishing stations.
There were 97 fish taxa identified from the trawl catch and 106 invertebrate taxa. The number of invertebrate species in 2008 is similar to 2007, and was significantly higher than in the past. This was a result of a broader sampling strategy and the increasing experience of personnel in identification of invertebrates.
Details on data collected, protocols followed, areas covered, and species captured are provided. Trends in abundance, biomass, and area occupied are presented for selected commercial species, and for species for which the data display a pronounced trend.
