TiwariG.N. 2200712An experiment was conducted to examine the energy use pattern in open and greenhouse fish ponds. The energy consumption was around 584.99 and 1027.22 MJ/50 m2 for open and greenhouse pond, respectively. The energy input-output, specific energy and energy productivity were found to be 0.070, 71.55 MJ kg-1 and 0.014 kg MJ-1 for open pond and 0.079, 63.60 MJ kg-1 and 0.015 kg MJ-1 for greenhouse pond, respectively. The energy ratio was higher in the greenhouse due to lower inputs and the specific energy was recorded low due to the higher yield.]]>Ayyappan, S., N.G.S. Rao, G.R.M. Rao, K. Janakiram and C.S.
