根据对环斑海豹生活史的研究，Phoca 继 hispida Schreber 之后，正在考虑其生物学原理，以便为开发利用提供合理的基础。关于海豹狩猎经济学的初步报告之前已发表（McLaren 1958），但并未广泛分发。 McLaren (1961) 对人口生态学和可持续狩猎产量进行了讨论，这是剥削问题的核心。本文关注的是那些无需采集标本即可在现场使用的方法。这项工作还没有完成，在此提出是希望那些北上活动的读者能够进行观察，以帮助测试和提高估计和方法的准确性。相关的观察结果列在论文的最后，可以看出大多数既不困难也不费时间。
upon studies of the life history of the ringed seal, Phoca Following hispida Schreber, its bionomics are being considered in order to develop a rational basis for exploitation. A preliminary report on the economics of seal hunting has been published previously (McLaren 1958), but was not written for wide distribution. A discussion of population ecology and sustainable hunting yield, which is central to the problem of exploitation, is given by McLaren (1961). The present paper is concerned with those methods that can be used in the field without collection of specimens. The work is by no means finished, and is presented here in the hope that readers whose activities take them to the north can make observations to help test and improve the accuracy of the estimates and methods. The pertinent observations are listed at the end of the paper, and it can be seen that most are neither difficult nor time consuming.
