鲸类生态旅游对主体动物的影响尚不清楚。监测这种影响的研究传统上集中在可观察到的表面行为上，尽管声音是鲸类动物的主要交流渠道。本研究监测了自由放养的宽吻海豚（Tursiops truncatus）的口哨声产生情况，以评估它们是否会以不同的速度对商业海豚游船做出反应。在1995/96年的南方春季和夏季记录了32小时的声音。结果表明，无论海豚在船只到达前的行为状态如何，当商业海豚游船出现时，哨子的产生明显增加。哨声数量的增加表明，海豚群体的凝聚力可能受到商业海豚游游旅游经营者的影响，或者可能有其他社会功能。对声音行为的监测为研究人类对鲸类动物的短期影响提供了另一种视角。
The impact of cetacean eco-tourism on subject animals is not clearly understood. Studies that monitor this impact have traditionally concentrated on observable surface behaviour despite the fact that sound is the primary communication channel for cetaceans. This study monitored whistle production in free ranging bottlenose dolphins (Tursiops truncatus) to evaluate if dolphins vocalise at different rates in response to commercial dolphin-swim boats. Thirty-two hours of sound were recorded in the austral spring and summer of 1995/96. Results indicate that whistle production is significantly greater in the presence of commercial dolphin swim boats, regardless of dolphins’ behavioural state prior to the arrival of the vessels. The increase in whistle production suggests that group cohesion may be affected during approaches made by commercial dolphin swim tour-operators or may serve some other social function. Monitoring vocal behaviour offers another insight into short-term human impacts on cetaceans.
