The dependency of many countries on marine organisms for food has resulted in severe population declines in cod, bluefin tuna, swordfish, and abalone, as well as numerous other marine organisms. In this seminar we will examine the sociological, political, and economic impacts of global depletion of fisheries. Questions addressed are: What is the scope of extinctions or potential extinctions due to over-harvesting of marine organisms? How are fisheries managed, and are some approaches to harvesting better than others? How do fisheries extinctions affect the society and economy of various countries, and ecosystem stabililty? How do cultural traditions of fishermen influence attempts to manage fisheries? Does aquaculture offer a sustainable alternative to overfishing the seas, and what is aquaculture’s impact on ecosystem stability? Three class hours per week. Requisite: Environmental Studies 12, Biology 23, or consent of the instructors. Not open to first-year students. Spring semester. Professor Temeles. Professor Dizard.
