Layer: Hecate Strait Synoptic Bottom Trawl Survey (0)

Name: Hecate Strait Synoptic Bottom Trawl Survey

Display Field: Survey_Year

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: The Hecate Strait (HS) synoptic bottom trawl survey was first conducted in 2005, and has been repeated every second year since. This survey is one of a set of long-term and coordinated surveys that together cover the continental shelf and upper slope of most of the British Columbia coast. The other surveys are the Queen Charlotte Sound (QCS) survey, the West Coast Vancouver Island (WCVI) survey, the West Coast Haida Gwaii (WCHG) survey, and the Strait of Georgia (SOG) survey. The objectives of these surveys are to provide fishery-independent abundance indices of all demersal fish species available to bottom trawling and to collect biological samples of selected species. The surveys follow a random depth-stratified design and the sampling units are 2 km by 2 km blocks.

Layer: Relevé synoptique au chalut de fond dans le détroit d’Hécate (1)

Name: Relevé synoptique au chalut de fond dans le détroit d’Hécate

Display Field: Année_de_relevé

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Le premier relevé synoptique au chalut de fond dans le détroit d’Hecate (DH) a été réalisé en 2005, et depuis l’opération est répétée tous les deux ans. Le relevé du détroit d’Hecate fait partie d’un ensemble de relevés à long terme et coordonnés couvrant le plateau continental et le haut du talus continental de la majorité de la côte de la Colombie-Britannique. Les autres sont le relevé du bassin Reine-Charlotte (BRC), le relevé de la côte ouest de l’île de Vancouver (COIV), le relevé de la côte ouest d'Haida Gwaii (COHG), et le relevé du détroit de Georgie (DG). Ces relevés servent à obtenir des indices d’abondance indépendants de la pêche pour toutes les espèces de poissons démersaux pouvant être pêchées au chalut de fond, ainsi qu’à prélever des échantillons biologiques sur des d’espèces précises. Ces relevés est réalisé selon un plan d’échantillonnage aléatoire stratifié, et les unités d’échantillonnage sont des blocs de deux kilomètres carrés.
