Abstract: In this study, the effects of polyculture on growth parameters such as weight gain, Glucose-6-Phosphate Dehydrogenase (G6PD) enzyme activities and plasma thyroid hormones levels of mirror carp (Cyprinus carpio) were tested during the two month. Monocultures of fish were included as controls. Although, initial values of the growth parameters were not significantly different (p>0.05); specific grow rates, plasma levels of T3 hormone, G6PD enzyme activities except T4 rose with time in both treatment and they were also different between the treatments (p<0.05). In conclusion, it was determined that a significant effect of polyculture on the growth of mirror carp.
