Dolphin-watching tourism is popular worldwide, but poorly managed boat traffic can significantly harm the welfare and long-term health of wild dolphin populations.
Wild dolphin welfare is increasingly threatened by recreational boating and commercial dolphin-watching operations. Dolphins in heavily visited areas show measurable physiological stress responses and altered time budgets, with less time for rest, nursing, and foraging. Calves are particularly vulnerable as mothers are forced to expend energy on evasive maneuvers rather than nursing. Swim-with-dolphin activities cause acute stress and disruption to natural behavior. Well-regulated dolphin watching with enforced distance limits, speed restrictions, and time-at-site limits can allow tourism while protecting welfare. Certification programs for responsible dolphin-watching operators provide a market mechanism for better practices.
