DFO Quebec Region Biodiversity of the whelk (Buccinum) dredge survey in the St. Lawrence Estuary

Study Extent

The survey is generally carried out between mid-July and the beginning of August. A fixed station sampling plan was used to cover all three sites. Since 2007, the sampling plan has consisted of 55 stations in Forestville, 26 stations in Pointe-aux-Outardes and 11 stations in Baie-Comeau. / Le relevé est généralement effectué entre la mi-juillet et le début d’août. Un plan d’échantillonnage à stations fixes était utilisé pour couvrir les trois sites. Depuis 2007, le plan d’échantillonnage est constitué de 55 stations à Forestville, 26 stations à Pointe-aux-Outardes et de 11 stations à Baie-Comeau.

Sampling

A Digby type scallop dredge consisting of four baskets and having a total width of 3.04 m was used for each survey. The baskets were lined with 19mm mesh Vexar ™ to collect small individuals. During dredging, the start and end positions were noted to calculate the distance traveled on each tow. The area covered at each tow was the product of the drag width and the distance. Since 2011, the average haul distance has been around 300 m. / Une drague à pétoncle de type Digby constitué de quatre paniers et ayant une largeur totale de 3,04 m a été utilisée à chaque relevé. Les paniers étaient doublés de Vexar™ de 19 mm de maillage afin de récolter les petits individus. Lors du dragage, les positions début et fin étaient notées pour calculer la distance parcourue à chaque trait. La superficie couverte à chaque trait était le produit de la largeur de la drague et de la distance. Depuis 2011, la distance moyenne des traits est d’environ 300 m.

Quality Control

Taxonomic names were verified on the World Register of Marine Species (WoRMS) to match recognized standards. The WoRMS match has been put in the scientificNameID field in the occurrence file. The special cases were noted in identificationRemarks and some selected specimens were confirmed with field photos. Data quality control were performed using the R packages obistools and worms. All sampling locations were plotted on a map to perform a visual check confirming that the latitude and longitude coordinates were within the described sampling area. / Tous les noms taxonomiques ont été vérifiés sur le registre mondial des espèces marines (WoRMS) pour correspondre aux normes reconnues. La correspondance WoRMS a été placée dans le champ scientificNameID du fichier d'occurrence. Les cas spéciaux ont été notés dans identificationRemarks et certains spécimens sélectionnés ont été confirmés à l'aide de photos de terrain. Le contrôle de la qualité des données a été effectué à l'aide des packages R obistools et worrms. Tous les emplacements d'échantillonnage ont été reportés sur une carte afin d'effectuer un contrôle visuel confirmant que les coordonnées de latitude et de longitude se trouvaient dans la zone d'échantillonnage décrite.

Method steps

1. Scientific name matching with WoRMS. / Correspondance des noms scientifiques avec WoRMS.

Principally mega-epibenthic invertebrate taxa were identified, along with some fishes and seaweeds. Species are identified at the lowest possible level. / Les taxons identifiés étaient principalement des invertébrés méga-épibenthiques, ainsi que des poissons et des algues de mer. Les espèces sont identifiées au niveau le plus bas possible.
