"description":"<div style='text-align:Left;'><div><div><p style='margin:0 0 11 0;'><span><span>This dataset represents abundance data of commercial size Sea Scallop (Placopecten magellanicus; ≥ 80 mm shell height) from 2011-2023 from the Bay of Fundy Inshore Scallop Survey. Data is binned into 5-mm shell height bins, is prorated to an 800 m tow length and 17.5 feet (5.334 m) drag width (i.e., representing an area swept of 4267 m2), and was collected using unlined dredge gear. Each row represents a tow and contains information such as tow date, cruise name, gear type, geographical coordinates (decimal degrees, WGS 84) and the Scallop Production Area in which the tow took place. Survey protocols are documented in Glass (2017). This dataset contains tow data from a comparative survey conducted in 2012 (Smith et al., 2013). Further, these data correspond to the publication of Hebert et al. (2025).<\/span><\/span><span /><span><span>References<\/span><\/span><span /><span><span>Glass, A. 2017.

Les données ont été regroupées en catégories représentant différentes plages de hauteur de coquille de 5 mm, et calculées au prorata pour un trait d\u2019une longueur de 800 m et une drague d\u2019une largeur de 17,5 pieds (5,334 m) (c.-à-d. une zone balayée d\u2019une superficie de 4 267 m<\/span><\/span><span><span>2<\/span><\/span><span><span>). Les pétoncles ont été recueillis à l\u2019aide de dragues non doublées. Chaque ligne représente un trait et contient des renseignements comme la date du trait, le nom de l\u2019expédition, le type d\u2019engin utilisé, les coordonnées géographiques (en degrés décimaux, WGS84) et la zone de production de pétoncles où le trait a été effectué. Les protocoles de relevé sont documentés dans le rapport de Glass (2017). L\u2019ensemble de données contient des données sur les traits effectués lors d\u2019un relevé comparatif mené en 2012 (Smith <\/span><\/span><span style='font-style:italic;'><span>et al.<\/span><\/span><span><span> 2013).
