DFO Quebec Region Ecosystemic bottom trawl surveys 2004-2022

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 Teleost et l'engin d'échantillonnage était un chalut à crevette Campelen 1800 avec un maillage de 44 à 80 mm et un revêtement dans le cul de chalut de 12,7 mm de maillage. Les données ont été standardisées pour un trait standard d'une durée de 15 minutes./ The vessel used was the CCGS Teleost and the sampling gear was a Campelen 1800 shrimp trawl with a mesh of 44 to 80 mm and a lining in the codend of 12.7 mm mesh. Data was standardized for a standard 15 minutes tow.

Quality Control

Les codes d'espèces utilisés pour identifier les captures dans ce relevé (https://github.com/claudenozeres/Taxon-IML) ont été mis en correspondance avec les noms scientifiques du Registre mondial des espèces marines (WoRMS, https://www.marinespecies.org/). La validation des identifications par le biais de photos ou de spécimens conservés est effectuée après le relevé. Les efforts d'identification se sont améliorés au fil des ans et sont documentés dans Dutil et al. 2006, Nozères et al. 2015 et Nozères et al. 2022. Des affiches et des photo-guides pour faciliter l'identification des captures sont annuellement révisés et publiés par C. Nozères (https://www.researchgate.net/project/Arctic-and-Atlantic-benthos, https://www.researchgate .net/project/NGSL-fish-biodiversity). Des photos de certains taxons sont publiées à titre de référence dans la galerie de photos du Registre canadien des espèces marines (CaRMS), https://www.marinespecies.org/CaRMS/photogallery.php. D'autres identifications sont affichés sur iNaturalist Canada pour obtenir une validation communautaire (ex. https://inaturalist.ca/projects/gulf-of-st-lawrence-canada-marine-species). Avec plus de 500 taxons documentés depuis 2004, la base de données évoluent constamment et des corrections d'identifications et de valeurs des captures (nombre et biomasse) sont effectuées régulièrement et seront appliquées dans les futures mises à jour. Certaines identifications retrouvées dans la base de données doivent être traitées avec prudence. Premièrement, le relevé n'est pas conçu pour échantillonner les espèces pélagiques, l'endofaune (vivant dans le sédiment) et la faune littorale. Des individus peuvent être capturés par le chalut mais leur présence (ou absence) et leur abondance n'est pas nécessairement représentatives. Deuxièmement, certaines espèces sont sujettes à l'enchevêtrement dans les mailles du chalut, particulièrement suite à une grosse capture. Des individus peuvent donc être enregistrés à des stations ultérieures alors qu'ils ne s'y retrouvent pas. Cette contamination croisée est particulièrement prononcée pour les plumes de mer, les éponges, les échinodermes et les crevettes. Des corrections pour contamination sont effectuées lorsqu'elles sont évidentes et sont indiquées dans les remarques des identifications./ The survey codes for captures (https://github.com/claudenozeres/Taxon-IML) were mapped to scientific names from the World Register of Marine Species (WoRMS, https://www.marinespecies.org/). Validation of capture records through photos or conserved specimens are performed post-survey. Efforts at identification have improved over the years, as documented in Dutil et al. 2006, Nozères et al. 2015, Nozères et al. 2022. Reference photo posters for invertebrate species and guides for fish species are annually revised and published by C. Nozères (https://www.researchgate.net/project/Arctic-and-Atlantic-benthos, https://www.researchgate.net/project/NGSL-fish-biodiversity). Reference photos are published on the Canadian Register of Marine Species (CaRMS) photogallery, https://www.marinespecies.org/CaRMS/photogallery.php. Other key examples are posted for community validation on iNaturalist Canada, e.g., https://inaturalist.ca/projects/gulf-of-st-lawrence-canada-marine-species. Additional photos from a Nozères 2003 guide are published on the St. Lawrence Global Observatory (https://ogsl.ca/en/home-slgo/). With other 500 taxa documented on the survey since 2004, corrections are still evolving for identifications and capture values that will be applied in future updates when ready. Attention is also needed for certain kinds of occurrence records. First, the bottom trawl survey is designed to sample groundfish and pandalid shrimp. Pelagic species, endofauna (buried), and nearshore fauna may be also sampled but not necessarily representative in quantities or even in presence (absence). Secondly, some species are prone to net mesh entanglement, especially following a large capture, and may then be recorded in subsequent stations that may take place in different habitats from their origin. This cross-set contamination is especially pronounced for sea pens, sponges, echinoderms, and shrimp. Corrections for contamination are indicated when obvious in identificationRemarks.

Method steps

1. Les données sont saisis en mer sur des formulaires papier ou dans une base de données. Elles sont ensuite 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). Une restriction d’une année sur la publication des données est appliquée, c’est-à-dire que l’année courante n’est pas incluse au moment de l'extraction./ Records are 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). Displayed records are delayed by one year from the last survey.

Principally demersal fishes and benthic epifaunal invertebrates, with captures of pelagic taxa also presented, and excluding seaweed (algae) / Principalement des poissons démersaux et les invertébrés benthiques d'épifaune, incluant aussi des captures de taxons pélagiques, et excluant les cas d'algue.
