| Summary: | A research survey on the Arctic surfclam (Mactromeris polynyma) was carried out by DFO in 2017 in the Estuary of the St. Lawrence River on the clam bed named Forestville using a "New England" type hydraulic dredge. The main objective of this survey was to study the spatial distribution of pre-commercial (anteroposterior length of less than 80 mm) and commercial (anteroposterior length equal or greater than 80 mm) sizes of Arctic surfclams as well as to assess the abundance and diversity of benthic species associated with the sandy habitat of the Arctic surfclams. Only benthic species data associated with Arctic surfclams habitat are presented in this dataset. Un relevé de recherche sur le stock de la mactre de Stimpson (Mactromeris polynyma) a été réalisé par le MPO en 2017 dans l'estuaire du Saint-Laurent sur le gisement nommé Forestville à l’aide d’une drague hydraulique de type « Nouvelle-Angleterre ». L’objectif principal de ce relevé était d’étudier la répartition spatiale des tailles pré-commerciale ... |
