The blood properties of free swimming carp were examined as a function of annual changes in urine properties. Statistically significant changes were found in Ht values and concentrations of K+ in the plasma. Throughout the examination period, U/P ratios with values below 1.0 were observed in osmolarity (minimum 0.06-maximum 0.19) and inorganic ions (Na+, 0.05-0.20; K+, 0.10-0.86; Ca2+, 0.03-0.19 and Mg2+, 0.02-0.60). Individual differences and annual changes in most of the blood properties were not particularly remarkable compared to those found in urine. The changing patterns of U/P ratios were close to those of the concentrations of urine components.
