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 )
Taxonomic names, and additional species images, may be consulted on
CaRMS, the Canadian portal of WoRMS (World Register of Marine Species).

Datasets of species occurrences are available on OBIS (Ocean Biogeographic
Information System) http://www.iobis.org, GBIF (Global Biodiversity
Information Facility) http://www.gbif.org, and may also be consulted on the
OBIS Canada IPT http://ipt.iobis.org/obiscanada/
