| dc.description | Increasing attention is being paid to initiate research and analysis on the energy cost in different food production technologies ranging from agriculture to livestock farming to aquaculture. Since aquaculture embraces different systems of farming of fish and shell fish in a variety of enclosures and also with different management measures it is essential to assess and compare energy budget of these farming systems. At times, the production rate is quite high in certain systems and quite low in others and in terms of monetary input output particular system may appear quite economically viable, yet when energy input/output is calculated, it may show a poor output. In fact, many high yielding technologies may show promising monetary economics but looking at the energy economics it may show a different picture. Further, on the basis of monetary economics, input/output ratio in different production systems cannot be easily compared globally whereas energy economics provides a uniform basis of input/output comparison of such farming systems in different parts of the world. Therefore, industrial energetics, budgeting the energy which may be required to carry out the various stages of a food product has been analysed. Biological energetics, describing the flow-pathways and efficiencies with which solar radiation is converted to produce food in an ecosystem by the plants and animals and fish is not under the purview of the paper since it is difficult to calculate the whole of biologi cal energetics which is dependent on the different fish species/sex/age, their metabolism and the food chain and their interaction with the ecosystem. However, the final biological product as fish is taken into consideration to calculate the input/output ratio. | |
