While the effects of stress on the mammalian brain are under thorough investigation, only a few researchers have explored how stress affects the brain of teleosts. Being the center of an elaborate nervous system, the fish brain is likely to be influenced by current and past stress and may also alter the perception of future stressors.
Many stimuli which fish in aquaculture encounter are processed by the brain, making the latter the place where most stressors first affect the fish irrespective of their quality and quantity. A better understanding of this primary stress response will lead to deeper insights in how stress influences fish and how negative effects on the fish might be lessened while positive ones may be utilized. Thus, the current investigations focus on the effects of different stressors on a variety of fish species. Additional projects are conducted in parallel aiming at improving the rearing conditions for fish in aquaculture.
