Using annual ecosystemic surveys to assess biodiversity in the Gulf of St. Lawrence / by Claude Nozères … [et al.].: Fs97-6/3149E-PDF
Important areas for biologically diverse communities were identified for the first time using data from ecosystem surveys including bottom trawl and plankton net sampling as well as seabird observations in the Northern and Southern Gulf of St. Lawrence. Taxonomic richness was examined by group for demersal fish, benthic invertebrates, pelagic taxa (fish and invertebrates), zooplankton, and seabirds. Benthic invertebrates and zooplankton were the most diverse groups (>100 taxa), followed by demersal fish, with 67 taxa consistently recorded from both regions. Pelagic taxa were incidental in trawl captures and of partial use in analyses. Up to 39 taxa of seabirds were observed from transects on the trawl surveys. The analyses showed several areas of high taxon richness located in regions broadly similar to previous reviews while making using of more recently available samples and taxonomic data. Combining all group layers indicated sectors with high overall taxonomic richness located in both deep (Laurentian Channel) and nearshore (Mingan, Belle Isle, Chaleur Bay, Shédiac, Cape Breton) areas in the Gulf and Estuary (head of channel, Manicouagan, Gaspé Peninsula).
