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.
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.
