早在1611年，居住在格陵兰东海岸和斯皮茨卑尔根岛之间的弓头鲸就是荷兰、德国和英国捕鲸者密集的商业捕鲸活动的目标。到1911年，生活在这些水域的弓头鲸没有显著的、永久的种群。为了了解弓头鱼的商业开发和它们最终灭绝之间的关系，我们必须确定它们衰落的时间顺序，首先估计最初的原始种群大小。在这篇文章中，我们比较和对比了四种方法，可以用来估计格陵兰-斯皮茨卑尔根弓头鱼的种群大小，在商业开发之前和期间。使用特定物种的生物学参数、延迟差异补充模型和历史捕鲸记录，我们重建了格陵兰-斯皮茨卑尔根弓头鱼在整个人类捕食时期的种群。我们估计，1611年大约有52,500头成年弓头鲸居住在格陵兰东海岸和斯皮茨卑尔根岛之间的水域。
As early as 1611 Bowhead whales resident between the east coast of Greenland and the island of Spitzbergen were the subject of intensive commercial hunting effort by Dutch, German and British whalers. By 1911 there was no significant, permanent population of Bowhead whales living in these waters. To understand the relationship between the commercial exploitation of the Bowhead and their eventual extinction we must determine the chronology of their decline, starting with an estimate of the initial, pristine stock size. In this paper we compare and contrast four methodological approaches that can be used to estimate the Greenland–Spitzbergen Bowhead stock size prior to, and during, commercial exploitation. Using species-specific biological parameters, a delayed-differ ence recruitment model, and historical whaling records, we reconstruct the Greenland–Spitzbergen Bowhead population throughout the period of human predation. We estimate that there were approximately 52,500 adult Bowhead whales resident in the waters between the east coast of Greenland and the island of Spitzbergen in 1611.
