2. Migration in anadromous brown trout
Sammanfattning : This thesis investigates the anadromous migration of brown trout (Salmo trutta) with the overall aim to improve stock management within the region. Several field studies were conducted in different streams and coastal areas on the west coast of Sweden specifically aimed to evaluate environmental triggers for migration (Paper I), migration pathways and strategies (Paper III and IV) as well as the genetic differentiation of anadromous populations of brown trout (Paper V).

3. Stress Coping Strategies in Brown Trout (Salmo Trutta): Ecological Significance and Effects of Sea-Ranching
Sammanfattning : Two distinct stress coping strategies, proactive and reactive, have been stated in various animal studies, each associated with a set of behavioural and physiological characteristics. In a given challenging situation, proactive animals show more aggression, a higher general activity and a predominant sympathetic reaction. LÄS MER

5. Age-class interactions in Atlantic salmon and brown trout: Effects on habitat use and performance
Sammanfattning : This thesis investigates the underlying mechanisms and the density-regulatory effects of age-class interactions, using juvenile Atlantic salmon (Salmo salar L.) and brown trout (Salmo trutta L.) as study species. LÄS MER
