Fisheries and Oceans Canada Quebec Region (DFO-Qc) conducts a multidisciplinary scientific bottom trawl survey in the estuary and northern Gulf of St. Lawrence (NAFO areas 4RST) every year since 1978. Survey data are collected following a stratified random sampling with a bottom trawl. The main objectives are to examine spatial and temporal changes in the distribution and relative abundance of fish and their assemblages and biological parameters of commercial species. Over the years, this survey has been conducted aboard five vessels: the MV Gadus Atlantica (1978-1994), the MV Lady Hammond (1984-1990), the CCGS Alfred Needler (1990-2005), the CCGS Teleost (2004-2022) and since 2022 the CCGS John Cabot. The objectives, the protocols, the identification of species as well as the trawl used during the various surveys changed over time. The data are therefore not directly comparable between these surveys. Comparative analyzes were carried between vessels and conversion factors are available for a number of species. Contact the team for more information. This data constitutes an OBIS version of the data collected from 1990 to 2005 onboard the CCGS Alfred Needler. At each sampling station, a URI shrimp trawl (81'/114') is towed for 25 minutes on the bottom at each sampling station. Physical oceanographic data are also collected at most stations using CTDs attached to the back of the trawl, a rosette and a zooplankton net. The OBIS view of this dataset includes presence and biomass information for fish and invertebrates species at the survey station locations. Data collected onboard the CCGS Teleost (2004-2005) are also available on Obis.Sampling Description
Study Extent
Des relevés sont effectués dans l'estuaire et le nord du golfe du Saint-Laurent chaque été en août. Les stations sont échantillonnés avec un chalut de fond en suivant un plan d'échantillonnage stratifié en fonction de la profondeur. Chaque année, environ 200 stations d'échantillonnage sont tirées aléatoirement dans des strates basées sur la profondeur, allant d'environ 40 m près des rives à près de 500 m dans les chenaux profonds./ Annual summer bottom trawl surveys are conducted in the Estuary and northern Gulf of St. Lawrence in August. Approximately 200 sampling stations are randomly attributed in depth-based strata, ranging from around 40 m near the shores to close to 500 m in the deep channels.Sampling
Le navire utilisé était le NGCC Alfred Needler et l'engin d'échantillonnage était un chalut à crevette URI (81'/114') . Les données ont été standardisées pour un trait standard d'une durée de 25 minutes./ The vessel used was the CCGS Alfred Needler and the sampling gear was a URI shrimp trawl (81'/114'). Data was standardized for a standard 25 minutes tow.Method steps
- Les données ont été saisis en mer sur des formulaires papier ou dans une base de données. Elles ont ensuite été archivées dans une base de données Oracle à l'Institut Maurice-Lamontagne. Les données collectées pendant le relevé comprennent le poids, le nombre et des caractéristiques biologiques (longueur, poids, sexe, maturité), ainsi que des données environnementales (profondeur, température, oxygène, salinité). Les noms scientifiques ont été associés à WoRMS, avec les codes inclus en tant que LSID dans le champ DwC de l'enregistrement d'occurrence de scientificNameID. Des informations supplémentaires sont disponibles dans les champs DwC de verbatimIdentification (nom de l'ensemble de données d'origine), identificationRemarks (commentaires sur le nom), taxonomicRemarks (commentaires sur le taxon) et lifeStage (par exemple, œufs)./ Records were entered while at sea into a database or on paper forms, subsequently archive in an Oracle database at the institute. Exported records included capture weight and numbers, and environmental data (depth, temperature, oxygen, salinity). Scientific names were mapped to WoRMS , with the codes included as LSIDs in the occurrence record DwC field of scientificNameID. Additional information is available in the DwC fields of verbatimIdentification (original dataset name), identificationRemarks (comments on name), taxonomicRemarks (comments on taxon), and lifeStage (e.g., eggs).
Taxonomic Coverages
Principally demersal fishes and benthic epifaunal invertebrates, with captures of pelagic taxa also presented, and excluding seaweed (algae) / Principalement des poissons démersaux et les crevettes, incluant aussi des captures de taxons pélagiques et d'invertébrés benthiques, et excluant les cas d'algue.
