Fish farming will flourish on badly drained land which is little suited to cultivation or which would need great capital expenditure to make it so. It will flourish in brackish and saline water unsuited for agricultural practices. Drainage water from existing agricultural schemes, which has become too saline for further agricultural use, can be salvaged for use in fish ponds (Hickling, 1962). Fish farming, as a source of resource utilization, should be allowed to compete with existing resource development programs. Until recently, Nepal has not fully benefitted from its valuable water surface. At the same time, there is a waste disposal problem in urban areas that could be partly solved by developing CFF and using the waste products of other sectors of the economy as fish food.
