Paperback. Condizione: New. Print on Demand. This book looks at the influence of the commercial fur seal industry on the Pribilof seal population for the years 1958-1962. It details methods used by the author and their team for estimating the number of pups born annually to assess the impact of hunting on the sustainability of t…he seal population. Techniques used to monitor the population included bull counts, herd and idle seal differentiation, and the tagging of pups and yearlings with physical checkmarks or Soviet tags. The insights gained from the research within contribute to an understanding of the cyclical nature of the seal population, and the impact that commercial hunting can have on the overall health and survival of the species.
