Document Summary
Note: please read chapter 15 (freshwater resources) and chapter 16 (water pollution) Discuss the relative contribution of wild-caught fisheries and aquaculture to fish protein and the techniques used to capture fish. Describe the requirements and limitations of current aquaculture processes including the positive and negative impacts of aquaculture processes on ecosystems. Describe the distribution of freshwater and how water is taken through the water cycle including groundwater aquifers. Discuss how water is obtained and used globally. Compare and contrast point and nonpoint sources of pollution. Describe the causes and consequences of eutrophication. Discuss the process of feminization in fish. Fisheries and aquaculture makes up of global protein consumption. Includes wild marine species (algae, invertebrates, fish and whales) Vital source of food (protein) and income for millions of people. Complex mix of biology, economics and social sciences - fisheries management. About 30% of fisheries are currently overfished, although there is variability amongst regions. Technological advances have resulted in declining ocean biomass.
