2. Effect of elevated pCO2 and environmental oxazepam on the behavior and physiology of teleost fish
Sammanfattning : This doctoral thesis investigated the effect of two aquatic pollutants on the behavior and physiology of teleost fish: i) elevated concentrations of carbon dioxide (CO2) in the context of ocean acidification and ii) low concentrations of the anxiolytic pharmaceutical oxazepam in the context of pharmaceutical pollution.Anthropogenic emissions of CO2 are lowering the pH of the oceans.

3. Intraspecific divergence and phenotypic plasticity in behavioural profiles of teleost fish
Sammanfattning : Behavioural differences between and within individuals can greatly affect the outcome of behavioural studies. In addition, behavioural interactions between individuals can compromise the health and welfare of captive fish. LÄS MER
4. Roles of Arginine-Vasotocin and Corticotropin-Releasing Hormone in Stress Responses and Agonistic Behaviour of Rainbow Trout
Sammanfattning : The neuropeptides arginine-vasotocin (AVT) and corticotropin-releasing hormone (CRH) are involved in the hypothalamic-pituitary-interrenal (HPI) axis. During stress, the HPI axis is activated and cortisol is released into the blood. In addition to their role in the HPI axis, AVT and CRH also have behavioural effects. LÄS MER
5. 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
