DFO Quebec Region Baie Sainte-Marguerite Snow Crab Trawl Survey 2006-2009

Study Extent

Sampling was done at 79 stations using beam trawl tows at depths of 7-198 m. The survey is carried out in May 2006 and May 2009. A fixed station sampling plan was used to cover the study area/ Échantillonnage réalisé à 79 stations au moyen de traits de chalut à perche (aussi connu sous le nom de chalut à bâton) de 7-198 m de profondeur. Le relevé était effectué entre mai 2006 et mai 2009. Un plan d’échantillonnage à stations fixes était utilisé pour couvrir la zone d’étude.

Sampling

The presence of the species in the catch was recorded. A beam trawl was used. The codend was lined with small mesh net in order to collect small individuals. The width of the trawl and the distance traveled calculated from the start and end positions of the haul are used to determine the area swept per haul. The duration of the tow is 10 to 15 minutes. Capture from the beam trawl was sorted and identified to nearest taxonomic level. / La présence des espèces dans la capture était enregistrée. Un chalut à perche a été utilisé. Le cul du chalut était doublé avec un filet de mailles fines afin de récolter les petits individus. La largeur du chalut et la distance parcourue calculée à partir des positions de début et de fin de trait sont utilisées pour déterminer la surface balayée par trait de chalut. La durée du trait est de 10 à 15 minutes. La capture du chalut du bâton étaient identifiée au meilleur niveau taxonomique.

Quality Control

Identification of crustacean and fish taxa were confirmed in laboratory, names were validated with World Register of Marine Species (WoRMS) / Identification des taxons de crustacés et de poissons étaient confirméé en laboratoire, les noms ont été validés avec le registre mondial des espèces marines (WoRMS).

Method steps

1. Quantities and measurements were performed for selected taxa, with presence-only information presented for this occurrence dataset / Des quantities et des mesures étaient faites pour des taxons sélectionnés, avec l'information de présence seulement qui est affichée avec de jeu de données d'occurrence.

Epifaunal benthic invertebrates and demersal fishes / Les invertébrés benthiques épifauniques et les poissons démersaux.
