在挪威北部和斯瓦尔巴群岛的西海岸，对六头小须鲸（Balaenoptera acutorostrata）安装了甚高频无线电发射器和四头声速深度发射器，并在视野范围内跟踪了长达 24 小时。在此期间，他们的呼吸频率被连续记录，并根据 Folkow 和 Blix（1992）在不同游泳速度和活动类型下估计他们的能量消耗。我们发现这些大型动物的游泳成本非常低，它们的估计每日能量消耗平均仅为 80 kJ kg(-1) day(-1)。
Six minke whales (Balaenoptera acutorostrata) were instrumented with VHF-radio transmitters and four with sonic speed-depth transmitters off the west coast of northern Norway and Svalbard and followed within view for up to 24 h. During such periods their respiratory rate was continuously recorded and their energy expenditure estimated according to Folkow and Blix (1992) at different swimming speeds and types of activity. We found that cost of swimming is remarkably low in these large animals and that their estimated daily energy expenditure on average only amounts to 80 kJ kg(-1) day(-1).
