In the present work, the recirculating aquaculture system (RAS) was evaluated for the intensive production of rainbow trout fingerlings (Orconhynchus mykiss) by monitoring water quality and production indicators. The operation of the RAS begins with the collection of water from a natural underground source (well) which enters the recirculation system through the mechanical filter, the biological filter, degasser, UV and oxygenation; to later be distributed to the tanks with fish and its return to the beginning of the system. The results of the water quality demonstrated the proper functioning of the system (biofilter, mechanical filter, UV, oxygen saturator and degassers) which was adequately monitored and controlled working in conjunction with the management of water renewal flows and trout health control. The main production indicators determined and evaluated were: accumulated mortality (1488 deaths, 0.99%), the specific growth rate (SGR) of the fingerlings obtained a value of 9.29 initially and reached 4.61 prior to harvest and the factor of feed conversion (FCA) on average 0.65. The application of the RAS system has allowed the reuse of water by 75% or more and a maximum monthly production of 400,000 fingerlings, proving to be efficient and more productive than the open conventional system.
