However, recent studies suggest that stress coping strategies are modulated by the epigenetic effects of social interaction. Previous studies show that the behaviour and physiology of fish is dramatically affected by social interactions, and that the brain serotonergic system plays a key for these effects. The serotonergic (5-HT) system is also known to be important for the expression of coping strategies. We will now explore to what extent behaviour and neuroendocrine stress responses of reactive and proactive rainbow trout is affected by social interaction. Moreover we will study the effects of stimulation on the 5-HT system on behavioural profiles and stress responses in a non-selected hatchery population as well as in rainbow trout strains selectively bread for high (HR) and low (LR) post-stress plasma cortisol, respectively. There is a large interest in generating stress tolerant fish strain that could cope with the unavoidable stress in aquaculture. This task is complicated by the fact that traits like stress tolerance and boldness is linked to aggressiveness. Moreover, environmental enrichment is often discussed, and is believed to have positive effects on fish welfare and performance. Still our knowledge on the effects of environmental enrichment on fish performance is very limited.
