Abstract


Recirculatory system of acvatic output is an alternative for classical acqaculture, because of its profitability. In this work it was experimented the accomodation and breeding possibilities of the Rainbow trout in the acvacol recilculatory system using urban water source.it was followed through to identify the weak parts of the system and the improvements that can be made, and also the operating performances that can be recieved in these conditions. The mass density was 100 trouts/m³. The age was 5 months with average weight 34 g. It was intensively foddered with granulated forage. The experiment lasted 5 months. The main phisico- chemical parameters pursued where: pH, O2, CO2, Cl, NO2, water temperature and cleanness. By the end of the experiment the average weight was 230g.
