Farmed fish under stress suffer from heart problems and their taste is thereby altered, reports the Norwegian newspaper Aftenposten, quoting a study by Ida Beitner Johansen, a doctoral student at the University of Life Sciences in Ås, town located 40 kilometers south of Oslo. So that the trout secrete more cortisol - the stress hormone - we put them in a pen with reduced dimensions.
The state of stress is accompanied by heart defects, a reduction in cell division - which has an influence on memory and behavior - and a lower quality taste. In humans, Aftenposten said, excess cortisol may be responsible for anxiety, depression, obesity or diabetes.
