In recent years mankind's consciousness has been aroused very strongly about the need for environmental protection and ecological preservation. It is of utmost importance that the people should be aware not only of the problems involved but also of the role to be played in protecting the environment.
Along with the peoples participation at the grass root level, the formal education programmed should be provided and implementing various environmental protection projects. In addition it is also very essential to develop environment friendly technologies and renewable energy sources following the principle of conservation.
While developing technologies for the benefit of man, it is also essential to study simultaneously their impact on the environment so that cyclic processes, which the nature has devised for conservation of resources is not affected.
The wastewater suspended problems have plagued the man ever since he started living in communities and the different communities have managed the wastewater disposal problem in varying degrees of success. In nomadic society man functions as an integral part of the ecosystem where in his waste would be assimilated in the system without creating any disturbance to other components of the ecosystem.
The urbanization, however, resulted in generation of complex wastewater in large amount which imbalance the ecosystem resulting in present waste problem. The use of aquaculture technology can be of immense importance in this regard.
Aquaculture is an important fast food farming sector. The current aquaculture production pattern provides a large gap between potential and actual yield. In order to make the composite operation of aquaculture more scientific it would be essential to approach with strong inputs of science and biotechnology.
Apart from other resources that could be put to fish culture, the other resources that could be recycled into culture subsystems, are the organic materials in terms of domestic sewage, residues from agricultural products, animal residues, in form of urine and excreta and a host of agro based industrial nutrients out puts, but also possess and treat a large number of wastes which would no other farming system can assuming importance in the context of environmental management.
