须鲸是地球上有史以来生活的最大的动物，许多种群在20世纪被猎杀，濒临灭绝(Clapham等人。1999年)。它们的恢复现在是一个关键的国际保护目标，它们在海洋生态系统中很重要，因为它们是可以通过营养循环促进初级生产的巨大消费者(Roman等人)。2014年)。然而，尽管对丰度进行了评估，以监测一些大型鲸鱼种群的恢复情况(例如，Barlow等人)。2011年，Laake et al.许多种群分布广泛，属于远洋种群，这种难以接近的状况通常阻碍了对恢复情况的量化评估(Peel等人)。2015年)。
Baleen whales are the largest animals ever to live on earth, and many populations were hunted close to extinction in the 20th century (Clapham et al. 1999). Their recovery is now a key international conservation goal, and they are important in marine ecosystems as massive consumers that can promote primary production through nutrient cycling (Roman et al. 2014). However, although abundance has been assessed to monitor the recovery of some large whale populations (e.g., Barlow et al. 2011, Laake et al. 2012) many populations are wide-ranging and pelagic, and this inaccessibility has generally impeded quantitative assessments of recovery (Peel et al. 2015).
