The carp is the main aquaculture species which is omnivorous, eating both vegetable and animal food. The aim was to analyze the research undertaken blood parameters at two varieties of carp fry culture, those common carp (Cyprinus carpio var. typica) and mirror carp (Cyprinus carpio var. specularis), which were grown with both natural food (zooplankton and phytoplankton) and with mixed food (natural and supplementary - cereal mixed with soybean meal). The weight of juveniles ranged between 25-45 g, and the blood parameters were determined during two periods, respectively in August and October. The values of blood parameters showed a physiological response similar to both varieties of carp, for similar living conditions. The number of erythrocytes, haemoglobin and the value of hematocrit were higher in summer than autumn, due to metabolic processes more pronounced in summer, when juvenile fish gets feed more intense. Moreover, the blood parameters were influenced by the variation of environmental factors, respectively the water temperature, its decrease causing the lowering of the analyzed blood parameters.
