Instruction, demonstration and exercises in population modeling, as applied to fishery resources. First principles of population dynamics are reviewed from the perspective of model building, and several dimensions of complexity are explored. A wide range of conventional stock assessment methods are introduced, as well as several advanced topics such as multispecies assessments, ecosystem considerations, spatial structure and risk analysis.

Integration of fundamental concepts of natural science and social science relating to management of living marine resources. This course utilizes a case study of a fishery to explore how knowledge and methods from a variety of disciplines including oceanography, biology, ecology, mathematics, and economics are used together in management of marine fisheries.
