Abstract
The experiments carried out regarding the topic „Research concerning the evaluation of the technological plasticity of the species Polyodon spathula (Walbaum, 1792) in a recirculating aquaculture system” are among national priorities concerning the development technology in the condition of recirculating aquaculture system. The purpose of this paper is to monitor the main physical-chemical parameters of water which can modify the metabolic processes of the culture biomass.
The experiment was carried out as a pilot programme in the “Recirculating aquaculture system engineering” Laboratory, within the Aquaculture, Environmental Sciences and Cadastre Department. The value of main physical-chemical parameters of the quality of water, both when water is introduced and evacuated out of the breeding system, which fit into the optimum limits for the breeding of sturgeons.

Key words: polyodon, recirculating system, physical-chemical parameters
