Images from Meso- and Bathypelagic Surveys in the Gully Marine Protected Area: III: Fish of the 2009 Survey
Notice bibliographique
Résumé
During 2007–10, Canada’s Department of Fisheries and Oceans conducted four midwater-trawl surveys, at meso- and bathypelagic depths, in The Gully – a large submarine canyon incised into the Scotian Shelf, east of Sable Island, the core of which has been within a Marine Protected Area since 2004. The surveys followed a fixed-station, depth-stratified design, with replicate sets both in daylight and at night. Most sampling used International Young Gadoid Pelagic Trawls (IYGPTs) –open nets with 60 m² mouth area– worked on double-oblique profiles. From the 2008 survey, the trawls were fitted with rigid (“aquarium”) codends and successfully took a number of delicate specimens in exceptional condition. Full details of the field methodologies have been presented by Kenchington et al. (2009, 2014). Catches of the abundance- or biomass-dominant fish species have been published by Thompson and Kenchington (2016) and Kenchington et al. (2018, 2020a). The ceratioid anglerfishes have been published by Kenchington et al. (2020b) and DNA barcodes derived from selected specimens by Kenchington et al. (2017). Identification of fish specimens is ongoing (in 2022), while damage in the nets means that not all can be identified to species. It is, nevertheless, sure that specimens from in excess of 240 fish species were captured. Many of those have rarely been seen and most had never been photographed in fresh condition. Thus, a variety of camera systems were taken to sea on the surveys and an attempt made to create images of every species captured. The resulting collection has been catalogued and lightly edited, while erring on the side of retaining any image that might prove useful in the future. Almost all of those retained are in their original formats and resolutions, though some copies subsequently edited for publication have been added. Because of file-size limits, the present collection includes only the 498 catalogued images of fish specimens from the 2009 survey, together with a copy of the entire catalogue of fish images. Individual files are uniquely numbered (from F09001 to F09498), with corresponding entries in the catalogue. The latter presents the contents of each image (typically only a species name, though some entries have more details) and such other image-specific details as are available. Not all images can be linked to particular specimens but, for those which can be, catalogue entries include cross-references to the survey-program’s catch database, which provides further details on the specimens concerned.

Amongst the named authors, the surveys were led by Trevor Kenchington, who also catalogued the images and, working with Cam Lirette, presented them here. Specimen identifications at sea and most of those ashore were by Daphne Themelis, while Merlin Best and Andrew Cogswell captured the images at sea.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
