heal.abstract	Growth performance, carcass composition, liver and blood parameters of scaled carp (C), Cyprinus carpio, and blue tilapia (T), Oreochromis aureus, reared for eight weeks in two monoculture (100% C and 100% T) and two polyculture (60%C-40% T and 40%C-60% T) conditions were investigated. In polyculture 40%C-60% T both species achieved the highest levels of specific growth rate and the lowest levels of food conversion ratio and carcass lipid content. In addition, they exhibited the highest values of plasma pO(2) and pH and the lowest values of plasma pCO(2), cholesterol and albumin, although the differences among treatments were not significant in the case of tilapia. Tilapia showed significantly lower plasma Cl- levels than under the other conditions. Carp in monoculture and tilapia in polyculture 60%C-40% T had the lowest levels of specific growth rate and significantly higher levels of liver lipids and plasma triglycerides than in the other groups. In addition, carp in monoculture exhibited a significantly higher haematocrit than in polyculture. No significant variations among treatments were observed concerning plasma cortisol, glucose, osmolality, Na+,K+, HCO3- and HCO3-/H2CO3 in either species. The combination of scaled carp and blue tilapia, in which blue tilapia were the main species, proved to be the best for both species. It was suggested that growth and physiological changes under mono- and polyculture rearing, in an intensive system, seem to be as a result of a different state of stress related to fish behavior.	en
