1. Age-class interactions in Atlantic salmon and brown trout: Effects on habitat use and performance
Abstract : 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. READ MORE

2. Salmonid behaviour under winter conditions
Abstract : Winter conditions are believed to play an important role in the population dynamics of northern temperate stream fish, challenging the ability of fish to physiologically and behaviourally adapt. Climate change is predicted to increase both mean temperature and temperature fluctuations, especially during winter, leading to dynamic environmental conditions in terms of river ice production and flow.

3. Environmental influences on the behavioural ecology of juvenile salmonids – the importance of rearing density
Abstract : Background and aims: Early environmental conditions are known to influence the phenotypic development of animals, including behavioural alterations. The overall aim of this thesis is to investigate the effects of density, social stability and structural complexity on growth, behaviour, and survival in the wild, using juvenile brown trout (Salmo trutta) and Atlantic salmon (Salmo salar) as model species.

4. Regulation of Leptin by Sexual Maturation and Energy Status in Male Atlantic Salmon (Salmo salar L.) Parr
Abstract : Leptin is a peripheral adiposity signal and a key hormone in energy balance regulation in mammals, acting as a link between nutritional status and the endocrine reproductive axis. If this is also the role of leptin in fish is not fully understood. READ MORE
