Whale and dolphin watching tourism provides wildlife experiences and conservation revenue, but poorly managed operations cause significant welfare harm to the animals observed.
Whale watching welfare involves a spectrum from minimal impact to significant harm depending on operator practices. Well-managed watching at appropriate distances with engine shutdown during whale proximity causes minimal disturbance. Poorly managed operations - multiple boats surrounding animals, following animals that attempt to leave, playing music or entering water near animals - cause acute behavioral disruption and cumulative stress. The spinner dolphin situation in Hawaii illustrates the cumulative welfare cost: dolphins that rest during daylight hours in protected bays face constant intrusion during their critical rest period. Swim-with-dolphin programs, particularly those involving wild dolphins, introduce human proximity into social spaces that disrupts natural behavior and can prevent normal daily rest and feeding schedules.
