The study develops a comparative analysis of the mean levels of blood glucose and of total serum proteins, as well as of the activity of superoxide dismutase in one summer-old common carp (Common carp), silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis), both prior to and following the wild wintering conditions of the 2006 - 2007 season. Such parameters represent important biochemical markers in stress evaluation, once known that a constantly increasing stress results in higher values of glycemy and in superoxide dismutase activity, although decreasing proteinemy. In the one summer-old fry taken into study, significantly higher post-hibernal values of glycemy - with 84.9% in bighead carp, 139.1% in common carp and 198.1% in silver carp -were recorded. Thermal stress reduces proteinemy with 11% in bighead carp and with 14% in silver carp while, in the case of common carp, spring viremia reduces proteinemy with 13%, comparatively with the mean pre-hibernal values.
