Introductory seminar: “Interactions between the life cycle of sea trout (Salmo trutta) and its habitats”

Focus for Fred Halléns’s PhD-project is the ecology and choice of habitat for brow trout especially in marine environments, see more below. His main supervisor is Johan Höjesjö  with med Per-Olav Moksnes (Marine sciences), Lina Rasmusson (BioEnv) and Daniel Palm (SLU, Umeå) as co-supervisors, and examiner is Lotta Kvarnemo, Department of Biological and Environmental Sciences. 

Short summary

Brown trout (Salmo trutta) is a fish species with a broad range of life history strategies present. Brown trout is considered a keystone species due to its ecological importance in the ecosystem. The focus in my PhD project is mainly about the anadromous form of brown trout, the sea trout. Sea trout interacts with a broad range of habitats throughout its life cycle and is therefore a potential actor in several different environments of ecological importance. The interactions between brown trout and its habitats are highly studied in freshwater environments, but similar studies in marine systems are fewer. To increase the knowledge about the importance of certain habitats for sea trout, and the role of sea trout in the different environments, this will be my main focus in the PhD thesis. To achieve this, I will perform studies in the field and in controlled environments to cover a broad range of aspects within the subject. The information about the habitat interactions of sea trout is of great importance when performing restoration measures, during management of sea trout and corresponding habitats, and to understand the dynamics in the ecosystems.
