The study was conducted to estimate the growth and survival of gold fish (average weight 1.15 g) in portable cements tanks (480 liter capacity) under different stocking density and environmental conditions . The portable cement tanks (diameter: 1 meter and height: 0.62 meter) were constructed with two cement rings . The fish were reared in three different stocking densities i.e. T1: 75 nos. /tank, T2: 125 nos. /tank and T3: 175 nos. /tank for a period of 60 days with two different tank environmental conditions i.e. (1) Tank without soil base and aquatic plant (2) Tank with soil base ( 4 inch soil base with cap cover (2 inch) of course sand) and aquatic plants (Vallisneria spiralis) . Cleaning and water exchange (25%) was done weekly twice in tanks without soil base and aquatic plant whereas, monthly twice in tanks with soil base and aquatic plant . Water quality of the tanks were measured at 15 days interval. The growth performance of gold fish was not significantly different in T1 and T2 treatments for both the environmental conditions however it reduced significantly T3 treatment . At the end of experiment, 100% survival was recorded in T1 and T2 treatments for both the environmental conditions compared to T3 (64% survival). Improved water quality was recorded in tanks with soil base and aquatic plants. The results of above study indicated that stocking density at 125 nos./ tank is optimum for gold fish culture in portable cement tanks. With this, environmental condition manipulation in cement tanks with soil base and aquatic plants have significant positive effects on water quality.
