Whale watching tourism can disturb cetaceans when not properly regulated. Evidence-based guidelines protect whale welfare while maintaining tourism value.
Cetaceans disturbed by whale watching boats experience behavioral changes including increased swimming speed, altered breathing patterns, and avoidance of previously used areas. Repeated disturbance prevents the efficient feeding needed to maintain energy reserves, which is particularly harmful during seasons when prey resources are critical. Calves separated from mothers by boat traffic can become isolated. However, well-regulated whale watching that follows international guidelines and maintains appropriate distances causes minimal harm and provides significant conservation value through public education and support for marine protection. The difference between responsible and irresponsible whale watching is substantial.
