A selection of 200 invertebrate taxa, routinely encountered on bottom-trawl surveys, are presented here to assist with their rapid identification while at-sea. General information on the surveys is available from Archambault et al. 2013. http:/ / www.dfo-mpo.gc.ca/ Library/ 347920.pdf.
The principal taxonomic reference for the region is: BruneI, P., Bossé, L. et Lamarche, G. 1998. Catalogue des Invertébrés marins de l'estuaire et du golfe du Saint-Laurent. Publ. spéc. can. sci. halieut. aquat. 126. 405 p. (available here: www.dfo-mpo.gc.ca/Library/223686.pdf )
