The paper analyzes the modifications produced in some biochemical indices (proteinemy and glycemy), determined in the blood of certain one year-old culture cyprinids, namely: common carp (Cyprinus carpio), silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis), subjected to some prophylactic antiparasitary treatments. The experiment was performed between April 2007 and April 2008, in 0.5 ha ponds, each basin being populated with 79% common carp (245 g/piece), 11% silver carp (475 g/piece) and 10% bighead carp (425 g/piece). In the reference pond, no treatments were applied, while the experimental variant was prophylactically treated both in the moment of ponds filling (April 2007) and during the growing period, with trichlorfon, applied in preventive doses of 0.1 mg/L, in two steps, and calcium chloride, 2 kg/ha, twice a week, respectively. The concentration values of the biochemical indices were determined one year after the experiment (March-April 2008). The results obtained attest that the preventive anti-ectoparasitary treatment applied to the three fish species has positive effects on their physiological condition, generally, on proteinemy and glycemy - especially. In the treated silver carp, spring proteinemy is 23% lower, while glycemy is 35% lower - comparatively with the reference. In the treated common carp, the two biochemical indices show an increasing tendency, with 19% in proteinemy and 27% in glycemy - respectively.
