Update of the 2009 Summer Scotian Shelf and Bay of Fundy Research Vessel Survey
By D. Clark, J. Emberley, C. Clark, and B. Peppard
The 2009 summer Scotian Shelf and Bay of Fundy research vessel (RV) survey was conducted between July 1 and July 28, 2009, onboard the CCGS Alfred Needler. The Alfred Needler completed 94 stations during the first leg of the survey, and 121 during the second leg. In Northwest Atlantic Fisheries Organization (NAFO) Divisions 4X5Y (strata 470-495), 77 valid tows were completed, while 119 valid tows were completed in NAFO Divisions 4VW (strata 440-466) and 6 sets were completed in strata 496-498 (Scotian Shelf edge; depth > 200fm). Hydrographic data were collected at all fishing stations.
There were 101 fish taxa identified from the trawl catch, and 118 invertebrate taxa. The number of invertebrate species in 2009 is slightly higher than in 2008, 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 and biomass are presented for selected commercial species, as well as for species for which the data display a pronounced trend.
