Whale watching in Patagonia began in 1973, with the southern right whale (Eubalaena australis) as a target. Thus far, only short-term effects of whale watching on behaviour have been evaluated. The southern right whale population is increasing locally and expanding to adjacent areas. We evaluated boat effects on the biological system through the analysis of breathing rate, linearity, reorientation rate and total distance travelled. Short-term movement patterns of SRW in the area are not severely affected by whale watching operations in Puerto Pirámide at this level of activity. However, significant changes in breathing rates in the presence of boats deserve further attention considering that whales return the same location. In light of the present work, the whales that breed at Península Valdés may be tolerant to whale watching boats.

巴塔哥尼亚的赏鲸始于1973年，南部的露脊鲸（Eubalaena australis）作为目标。迄今为止，仅评估了观鲸对行为的短期影响。南部的右鲸种群在当地增加，并向邻近地区扩展。我们通过分析呼吸速率，线性，重新定向速率和总行进距离来评估船对生物系统的影响。在这一活动水平上，波多黎各皮拉米德的鲸鱼观赏活动并未严重影响该地区SRW的短期移动方式。但是，考虑到鲸鱼返回相同的位置，在有船存在的情况下，呼吸速率的显着变化值得进一步关注。根据目前的工作，在PenínsulaValdés繁殖的鲸鱼可能会容忍观鲸船。
