We perform research on fish within the domains of ecology, genetics and physiology. Our goal is to increase the knowledge about fish biology, with applications to fish in nature and in culture. Applications of our research include management of fish populations, dealing with questions of surveillance, population analyses, habitat restoration, and stocking. Also studies on the individual level, for example, regarding behaviour and physiology, are needed to understand regulatory mechanisms within populations and fish communities.
- How can we improve habitats in order to secure the sustainability of fish populations? (restoration of spawning areas, facilitation of fish migration)
- How can we maximise survival of fish stocked into the natural habitats? (Breeding, feeding, behaviour, stress tolerance)
- How does fish influence their habitat? (interspecific interactions, addition and recycling of nutrients)
- How can we detect and predict changes in fish populations? (habitat surveillance, genetic analyses, modelling)
- What is the effect on the fish community by the introduction of non-endogenous fish, caused by stocking, invasive species and escapes from fish farms, in terms of competition and predation (behaviour, population dynamics, fitness)
To be able to carry out our research in an efficient way, there is constantly a development of methods to collect reliable data. Methods we use and develop relate to, for example, capture, individual tagging and tracking, behaviour studies, genetic analyses and modelling.
Our research team consist of people with different competences that together contribute to a magnitude of projects concerning both wild fish populations and fish in culture.
- Behaviour differences within and between perch populations - natural selection or previous experience?
- Application of behavioural genetics to improve animal welfare in the breeding program of Arctic charr
- Impact of boat traffic noise on coastal fish growth and reproduction
- Effects of salmonids on ecosystem processes: cycling and spatial translocation of nutrients
- Individual differences in behaviour
- Algae production for fish feeds and waste water treatment
- The quality of hatchery reared Atlantic salmon
