The study analyzes comparatively some bodily indices and coefficients (profile index, Kiselev index, index of fleshy and the Fulton coefficients) in Aristichthys nobilis (bighead carp) and Hypophthalmichthys molitrix (silver carp), from the first up to the fourth growth summer. The main objective of the investigation referred to the evaluation of the health condition of the piscicultural populations under analysis, evidenced by the most representative bodily indices and coefficients expressing the fish-breading maintenance, followed by the statistical processing of the results obtained. Thus, for each parameter in part, there were calculated mean error and standard deviation, median, mode, sample variance, range, mean confidence level (95%), as well as mean variation and precision coefficient. The analysis performed evidenced a harmonious development of the investigated populations, which showed good maintenance condition, in close correlation with the main physicochemical parameters of the growing media: water temperature, amount of oxygen dissolved in the water and water pH. On the basis of the values of the investigated parameters, we may conclude that individuals of Aristichthys nobilis species evidence the most pronounced corpulence, comparatively with the ones of Hypophthalmichthys molitrix in the first two stages of development and, at the same time, the best physiological condition starting with the second summer of growth up to the last stage of development under investigation.
