Friedrich M., 1997. Impact of high level of cortisol, observed in the blood of intensively reared two-year-old carp (Cyprinus carpio L.), on the levels of electrolytes and blood osmolarity. Acta Ichthyol. Piscat. 27 (1): 95-101.
The present study revealed that intensive culture of two-year-old carp, using a high-fat diet (group 1) or a high-carbohydrate diet (group 2), causing a statistically significant rise of cortisol level, resulted in statistically significant rise in potassium ion concentrations as well as a statistically significant drop in chloride ion concentrations (group 1 only).
