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

Fokus för Fred Halléns doktorandprojekt är havsöringens ekologi och habitatval, och dess interaktioner med omgivningen, huvudsakligen i den marina miljön, se mer nedan. Hans huvudhandledare är Johan Höjesjö med Per-Olav Moksnes (Marina vetenskaper), Lina Rasmusson (BioEnv) och Daniel Palm (SLU, Umeå) som bihandledare, och examinator är Lotta Kvarnemo.

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.
