Popis: Abstract Hydrological data were collected from the six ponds of 0.05 ha size in the farm of the Central Institute of Freshwater Aquaculture, Bhubaneswar, India. Data on rainfall, run-off, evaporation, and seepage were collected from these ponds for the years 2013 and 2014. The rainfall was 175 ± 3.0 and 202 ± 5.0 cm in 2013 and 2014, respectively. The run-off was 36 ± 1.2 and 29 ± 1.0 cm, in these ponds, in 2013 and 2014, respectively. Average evaporation was 0.30 cm/d in 2013 and 0.37 cm/d in 2014. The average seepage was 0.22 cm/d in both the years. The loss from the evaporation and seepage could be compensated through the regulated inflow of groundwater from wells/canals. The total amount of well/canal water in an average year to compensate the water loss through evaporation and seepage was calculated and for the 1.0 ha pond, 9800 ± 200 m3 of water in 2013 and 13,700 ± 300 m3 of water in 2014. Accordingly, the harvested water could be 12,000 ± 200 m3 in 2013 and 15,000 ± 300 m3 in 2014, respectively. The consumptive water use was 3.15 ± 0.3 m3/kg fish and 3.35 ± 0.2 m3/kg fish in 2013 and 2014, respectively. The total water use in these embankment ponds was 5.15 ± 0.5 m3/kg fish and 5.66 ± 0.6 m3/kg fish in 2013 and 2014, respectively.
