Biodiversity of the Mingan Archipelago Icelandic Scallop survey

A research survey of Iceland scallops (Chlamys islandica) using a dredge has been carried out by DFO (Fisheries and Oceans Canada) every 1 or 2 years since 1990 in the Mingan Archipelago ( fishing areas 16E and 16F). The main objective of this research survey was to assess Icelandic Scallop stocks. Another objective was to documented taxa in the captures associated with scallop habitat according to a fixed sampling plan. Occurrences by species (or taxon) are presented by station. The taxonomic and geographical validity of the data was checked and the World Register of Marine Species served as the taxonomic authority for naming all taxa recorded during the survey. Epibenthic invertebrates (mainly molluscs, echinoderms and crustaceans) as well as demersal fish were identified from the dredge catches.

The study area is located around the Mingan Archipelago and the sampling of scallop beds is carried out at depths of 8 to 136 m, generally around 40 to 60 m. Sampling is done along transects at fixed stations in the study area. Sampling is done with a lined Digby scallop dredge (20 mm mesh) over approximately 150 m along the seabed. The four baskets of the dredge are examined for all scallops. Next, a basket (the first on the starboard side) is sorted and examined for associated species. Most specimens are counted by taxa. The presence or relative abundance of undersized and numerous, or colonial, organisms is noted. Special cases are sometimes retained for taxonomic analysis, for example, ascidians (to monitor invasive species) and sponges (to document new species).
