众所周知，狩猎大大减少了所有须鲸的数量，但对以前鲸鱼丰度的可靠估计是难以捉摸的。根据线粒体DNA序列变异的结合模型，北大西洋鲸鱼的遗传多样性表明，大约有240，000头座头鲸，360，000头长须鲸和265，000头小须鲸。对长须鲸和座头鲸的估计远远大于以前对捕鲸前种群的估计，比现在的种群估计高出6至20倍。这种差异表明，有必要对历史上的鲸鱼数量进行定量重新评估，并从根本上修改我们对海洋自然状态的概念。
It is well known that hunting dramatically reduced all baleen whale populations, yet reliable estimates of former whale abundances are elusive. Based on coalescent models for mitochondrial DNA sequence variation, the genetic diversity of North Atlantic whales suggests population sizes of approximately 240,000 humpback, 360,000 fin, and 265,000 minke whales. Estimates for fin and humpback whales are far greater than those previously calculated for prewhaling populations and 6 to 20 times higher than present-day population estimates. Such discrepancies suggest the need for a quantitative reevaluation of historical whale populations and a fundamental revision in our conception of the natural state of the oceans.
