ABSTRACT
Due to the steady rise in population throughout the world, considerable attention is being given to the problems of increasing protein resources and enhancing the biological value of different food products. The area under fish ponds and fish yields are increasing, pisciculture technology is improving, and fish farming becoming accepted as a branch of agriculture. The demand for fish as a nutritious food for man is increasing with each passing year. Simultaneously, inland resources in general and fish ponds in particular are being threatened by pollution from industrial effluents and toxic chemicals. The pond fisheries of the USSR have all the requisite conditions for large-scale development by collective and state enterprises. A rational development of pond fisheries is based on culturing those valuable species and varieties of fish for food which, over a short period, provide a high quality product. Pond pisciculture has already proved a profitable venture and in a number of places has expanded rapidly.
