Provides an overview of how we develop the best available information and science for fisheries management. The course will review the decision-making process in fisheries management and evaluate various tools and approaches that can be used in generating the best available information to inform ecosystem-based fisheries management. These tools and approaches will include single species fisheries models, multispecies models and full systems models. Advantages and disadvantages of each approach and needs to develop ecosystem-based fisheries management in changing environments will be discussed. The course requires familiarity with quantitative methods, but emphasizes current literature and case studies as main learning elements.
