The aim of the present study was to evaluate the effect of dimethyl sulfoxide (DMSO) on early development, growth and mortality of early life stages in common carp. Tests were performed from fertilized egg to the end of the larval period with continuous exposure to DMSO at concentrations of 0.2, 0.5, 1.0 and 5.0 mL/L. Mortality of embryos and larvae, intensity of development and growth, weight and occurrence of abnormalities were analyzed. DMSO exposure at all the tested concentrations did not result in any lethal effects or abnormalities over the entire test period (29 days). Growth indicators were similar in DMSO treated (at concentrations of 0.2, 0.5 and 1.0 mL/L) and control groups. However, mean body weight (35+/-9 mg) of larvae exposed to the highest DMSO concentration (5 mL/L) tested was significantly lower compared to the control (45+/-14 mg).
