Abstract

This work seeks to demonstrate how light pollution impacts fishing activities, including catch rates and the profits of fishermen. Our goal is to examine how light pollution affects the fishing dynamics of sardines and anchovies in the Casablanca-Rabat region of Morocco, within a bioeconomic framework involving these two marine populations. In this article, we show that our model is well posed by studying the positivity and the boundedness of our system, and then we show the local stability of the interior equilibrium point. Then, we move on to calculating the fishing effort that maximizes fishermen’s profits and catches under two main constraints: The influence of light pollution on the sustained viability of the sardine and anchovy populations. Using data reported by the National Fisheries Research Institute (INRH), we obtain detailed results in numerical simulations.

调查光污染对渔业生物经济动态的影响
摘要 这项工作旨在证明光污染如何影响捕鱼活动,包括渔获率和渔民的利润。我们的目标是在涉及摩洛哥卡萨布兰卡-拉巴特地区沙丁鱼和凤尾鱼的生物经济框架内,研究光污染如何影响这两个海洋种群的捕捞动态。在本文中,我们通过研究我们系统的实在性和有界性,证明我们的模型具有良好的假设性,然后我们展示了内部平衡点的局部稳定性。然后,我们继续计算在两个主要约束条件下渔民利润和渔获量最大化的捕捞努力量:光污染对沙丁鱼和凤尾鱼种群持续生存能力的影响。利用国家渔业研究所(INRH)报告的数据,我们通过数值模拟获得了详细结果。

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.
