Dolphin watching tourism can benefit or harm dolphins depending on how it is conducted. Responsible operators educate and inspire while irresponsible ones cause chronic disturbance.
High-intensity dolphin watching tourism causes documented behavioural disruption. Dolphins in heavily visited areas spend less time resting, feeding, and nursing calves. Repeated approaches by multiple boats force dolphins into faster swim speeds and disrupt natural rest cycles. Swim-with programs cause acute stress responses in wild populations. Well-regulated whale watching with minimum approach distances and limited numbers of boats per group causes far less disruption while still providing conservation benefits through public engagement.
