Abstract:
Short-finned pilot whales (Globicephala macrorhynchus) are deep-diving odontocetes that forage at depths of more than 800 m. Due to difficulties in distinguishing this species from its congener, the long-finned pilot whale (G. melas), there was limited information on the distribution and habitat use of this species in the Northwest Atlantic until recently. Short-finned pilot whales are taken as bycatch in the pelagic longline fishery, and the Northwest Atlantic stock of short-finned pilot whales is now considered to be strategic under the Marine Mammal Protection Act due to recent increases in bycatch rates. In addition, waters in the Northeast shelf of the US have shown some of the highest rates of warming in recent years, and the effects of this warming on pilot whale habitat use and distribution are unclear. An improved understanding of patterns of movement, habitat use, and behaviour of short-finned pilot whales is necessary in order to generate a full assessment of the threats faced by this species. Here we integrate data from telemetry studies, fisheries observer surveys, and stranding networks to elucidate environmental drivers of habitat use and fisheries bycatch in order to inform management and mitigation measures to decrease bycatch.
