Fig 2. Humpback whale sightings and aquaculture locations.

Fig 2

Seasonal sightings of humpback whales from the BC Cetacean Sightings Network are plotted in relation to humpback whale-aquaculture incident locations (red points) and licensed aquaculture sites in 2018. Peak season (yellow points) was defined as April to October and off season (purple points) was defined as November to March. Reported entanglement locations (in decimal degrees) were mapped using ArcGIS Pro 3.0.2 with public domain Natural Earth base maps (naturalearthdata.com). Sightings reports from 1983–2022 are included. Sightings data supplied by the BC Cetacean Sightings Network. Sightings are opportunistic and not corrected for effort.
