Fundamentals of population dynamics - basic knowledge of biology and ecology of marine organisms, in particular those that are harvested - some knowledge of fisheries and fishing gear types
By the end of the course, students should have a good understanding of the different fishing gears, how they are used and their impact on living resources and the environment. They will also understand the concepts and methodologies that form/provide the basis of fisheries assessment , the philosophy behind the different types of models, their data requirements, and their limitations. The students should be capable of choosing the right model / methodology for stock assessment and management , and have the ability to interpret model outputs and formulate management advice.
