Tambraparni barb is one of the endangered barb variety from Western Ghats, which was successfully domesticated and bred at ICAR-Central Institute of Freshwater Aquaculture, Bhubaneswar, India. It has a global ornamental potential in planted aquarium and are exported to many nations from the wild. An experiment was conducted for 45 days to estimate the optimum quantity of Hydrilla plant required for better growth and survival of tambraparni barb. Three-month old juveniles having length and weight 20.2±0.5 mm and 296±25 mg, respectively are reared in FRP tanks of 360 litres water holding capacity (120×60×50 cm3) without providing aeration. Four treatments with different quantities of Hydrilla, viz. 0.25 kg, 0.5 kg, 1 kg, 1.5 kg and a control tank without Hydrilla was taken and 25 number of fishes were stocked per tank. The fishes were fed with a commercial feed ad libitum. The present study concludes that the optimum requirement of Hydrilla plant required for successful rearing of tambraparni barb with significantly better growth and survival is 0.5-1 kg Hydrilla, may be suggested for rearing as it provides better shelter and environment.
