Beluga whales are highly social, vocal Arctic cetaceans facing accelerating pressures from climate-driven sea ice loss, increased shipping noise, oil and gas exploration, and subsistence hunting. Their welfare is deeply tied to intact acoustic environments and stable sea ice habitat.
Belugas are highly cognitively complex and socially dependent; individuals separated from their social groups show elevated cortisol and suppressed immune function. Entanglement in fishing gear, ship strike, and acoustic disturbance from seismic surveys cause direct welfare harm. Subsistence hunting by Indigenous communities is managed under co-management agreements in Canada and Alaska, but some populations remain under unsustainable pressure. Marine protected area designation around critical summering aggregation sites reduces multiple stressors simultaneously and represents the most effective welfare and conservation intervention available.
