摘要

The aim of this paper is to assess the growth performance of tilapia (Oreochromis Niloticus) in a recirculating aquaculture system, in order to review the possibility of introducing this species in Romanian aquaculture. The experiments was done in October-December 2011, during which feeding was done only with fodders grain proper age, from Nutra category. At the start of experiments, the system was populated with tilapia which present an average body weight of around 8 g. Average daily growth rate recorded was 0.8 g/day and a specific growth rate of 3.6%/day on the average fish biomass. The evolution of physical-chemical parameters of the technological water during the experiment was within the limits of optimal growth. Biological material (tilapia) presented a good development rate, registering a 100% survival, while the water temperature fluctuated and at certain times was not optimal for development of tilapia.
