Spatial-temporal variation in Greenland shark (Somniosus microcephalus) bycatch in the NAFO Regulatory Area

Spatial and temporal variation in Greenland shark (Somniosus microcephalus) bycatch occurrence was investigated using At-Sea Fisheries Observer data and MaxEnt, a maximum entropy species distribution model. Within the Northwest Atlantic Fisheries Organization Regulatory Area (NRA), the Flemish Pass,...

Description
Summary:Spatial and temporal variation in Greenland shark (Somniosus microcephalus) bycatch occurrence was investigated using At-Sea Fisheries Observer data and MaxEnt, a maximum entropy species distribution model. Within the Northwest Atlantic Fisheries Organization Regulatory Area (NRA), the Flemish Pass, the slopes of the Flemish cap, and the shelf edge of Divisions 3NO contained areas of suitable habitat where Greenland shark bycatch is expected to occur. However, it should be noted that there are major areas of Greenland shark bycatch outside the NRA, in the Canadian and Greenland Exclusive Economic Zones (EEZ). En prensa
