摘要

在本文中，我们提出了一个简单的理论、稳态平衡、捕食者-猎物模型，用于海洋哺乳动物和鱼类的联合管理。作为一个实证案例，我们选择了北欧-波罗的海国家的鳕鱼和灰海豹，并考虑了与后者相关的一些好处和成本。我们表明，最优灰海豹种群远低于实际种群，并且这一结果对相关参数值的变化是稳健的。这一结果可以解释为，捕捞鳕鱼的利润远高于灰海豹的净收益。

Joint management of marine mammals and a fish species: The case of cod and grey seals in the Nordic‐Baltic Sea countries

In this paper, we present a simple theoretical, steady‐state equilibrium, predator‐prey model for the joint management of marine mammals and a fish species. As an empirical case, we choose cod and grey seals in the Nordic‐Baltic Sea countries, and several benefits and costs related to the latter are considered. We show that the optimal grey seal population is much lower than the actual population, and this result is robust to variations in relevant parameter values. This result can be explained by the fact that the profit from harvesting cod is much higher than the net benefits from grey seals.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
