Beluga whales face welfare threats from shipping noise pollution, commercial hunting, captivity for entertainment, and the rapid transformation of Arctic ecosystems by climate change.
Wild belugas experience chronic welfare harms from increasing Arctic shipping traffic that masks their acoustic communications — essential for social cohesion, navigation, and cooperative hunting. Noise pollution has been linked to elevated stress hormones, altered behaviour, and strandings. Captive belugas suffer significant welfare costs: limited space relative to their natural oceanic ranges, acoustic overstimulation from the crowd noise of entertainment venues, and social disruption when pods are artificially composed. Many captive belugas show chronic stress indicators. The Georgia Aquarium's proposal to import wild-caught belugas sparked major campaigns that ultimately succeeded in blocking the import on welfare and conservation grounds.
