Tilapia (Oreochromis niloticus) was reared in a fully control system to evaluate the growth performance. A trial of the experiment was conducted for the period of one year (May to April) in cemented pond having an area of 40,000 ft2 and filled up to one foot with water. Hence, 100,000 fingerlings of tilapia (O. niloticus) with the mean initial weight of the 10 ± 2.1 gram were stocked within a volume of 40,000ft3 of water. The fish were fed with plant origin formulated pellet consisting 19% protein, prepared from rice by-product. All the essential water quality parameters including dissolved oxygen, temperature, pH, TDS, conductivity, salinity and NH3 were measured and maintained in the required range. Fish were harvested with a mean final weight of 520 ± 80.2 gm; with an average final weight gain of 510 ±78.1. During the study, the survival rate was recorded 99% with specific growth rate (SGR) 0.47% per day. In result, a production of 51,480 Kgs was obtained from 40,000ft3 of water. Hence, tilapia can be cultured in a control system to produce maximum production by utilizing a minimum area
