The fish fauna is diverse. No other vertebrates, like birds, mammals, reptiles or amphibians, include more species than the bone fishes. They exhibit an impressive variety of adaptions to aquatic habitats. Their impact on aquatic communities and ecosystems is overwhelming. Further, fish populations provide valuable resources for humans throughout the world.
This course focuses on the responses of fishes to their environments and the interactions between populations in a community. The topic of the course is essential for all students interested in fish biology, fisheries, habitat management and conservation of fish populations.
The course covers both theory and practical applications of fish ecology and behavior. It includes training in best practice of both field- and laboratory methods.
The course is given at an advanced level and consist of lectures, seminars, field- and laboratory exercises and an individual project work.
Students are upon completion of the course expected to be able to:
- account for habitat use over the life cycle in economically and ecologically important fish species in the Baltic Sea and its drainage basin;
- account for the importance of predation, competition, and trophic interactions for population dynamics;
- describe and provide examples of how fish populations are affected by climate changes;
- argue coherently about the influence of fish harvest and biomanipulations on populations and ecosystem functions;
- account for conservation and management issues related to fish;
- design, conduct, thoroughly analyze and report on laboratory experiment;
- perform standard fish ecology samplings and evaluate the results;
- plan and carry out studies individually, addressing issues in fish ecology, and communicate the results both orally and in text.
Bachelor´s degree including Biology 60 credits, incl. Ecology 15 credits, or corresponding course qualifications.
