Name: Lobster Proxy/Substitut de Homard - 2018

Display Field: GRID_ID

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Proxied dataset of inshore lobster commercial fishing for 2018 in the Newfoundland and Labrador region. Only lobster harvested from the Newfoundland and Labrador region are included, based on species sought.Commercial data for the inshore lobster fishery does not require a set of coordinates be provided for catch records. With zero georeferenced inshore lobster records, the inshore lobster fishery leaves a major data gap in one of Newfoundland and Labradors largest fisheries. The Gulf region created a lobster proxy mapping tool, which associated each commercial lobster record with the most likely 10km2 hexagon grid cell based on a number of weighted variables. The tool was adopted by the Newfoundland and Labrador region and altered to work with its own variables which include human use, habitat, accessibility, area/location, home port distance, traditional ecological knowledge and depth. Each hexagon represents the summed total weight of all records associated with a particular hexagon. Ensemble de données de substitution sur la pêche commerciale côtière du homard en 2018 dans la région de Terre-Neuve-et-Labrador. Seuls les homards pêchés dans la région de Terre-Neuve-et-Labrador sont inclus, selon les espèces recherchées.Les données commerciales pour la pêche côtière du homard ne nécessitent pas que l’on fournisse un ensemble de coordonnées pour les données sur les prises. Étant donné qu’il n’existe pas de données géoréférencées pour le homard côtier, la pêche côtière du homard laisse une lacune importante dans les données de l’une des plus importantes pêches de Terre-Neuve-et-Labrador. La région du Golfe a créé un outil de cartographie de substitution du homard, qui a associé chaque donnée commerciale sur le homard avec la cellule hexagonale de 10 km2 la plus probable en fonction d’un certain nombre de variables pondérées. L’outil a été adopté par la région de Terre-Neuve-et-Labrador et modifié pour fonctionner avec ses propres variables, qui comprennent l’utilisation humaine, l’habitat, l’accessibilité, la zone ou l’emplacement, la distance du port d’attache, les connaissances écologiques traditionnelles et la profondeur. Chaque hexagone représente le poids total de toutes les données associées à un hexagone particulier.
