Impact on Energy Consumption in Greenhouse Fish Production

An 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 m super(2) 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 super(-1) and 0.014 kg Mr super(-1) for open pond and 0.079, 63.60 MJ kg super(-1) and 0.015 kg MJ super(-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.
