520			_a"Today the importance of fish culture is being realised as never before, in the face of mounting pressure of population explosion. Fish culture is the rational cultivation of fish in a confined water mass, where rearing is not left to the mercy of nature. Fish culture in natural waters is concerned with the replenishment and improvement of the fish stocks of rivers, lakes, reservoirs, and seas. The increasing impact of man on such waters (water pollution and construction) has impeded or disrupted the natural replenishment of fish stocks. Thus, the rearing of fish, that is, fish-farming, is needed to maintain the existing fish life and to improve an ichthyofauna of minor value. Semimigratory (pike-perch, carp, roach) and migratory fishes (sturgeon, beluga, stellate sturgeon, inconnu, Atlantic salmon, chum salmon, pink salmon, Baltic vimba, and kutum) are particularly threatened. It is the most common method of fish culture. Water is maintained in an enclosed area by artificially constructed ponds where the aquatic animals such the finfish and shellfish are reared. The ponds may be filled with canal water, rain water, bore well water or from other water sources. The pond must be constructed after proper site selection. The climate, topography, water availability and soil quality of the region influence the character of the fish pond. For watershed ponds, water required to fill and maintain the pond water is entirely sourced from the watershed runoff, though groundwater (bore well) and surface water (stream and reservoirs) can be used as an additional water sources. This work will be a highly useful reference tool for students, teachers, academicians, and all who interested in pisciculture." -- Back cover
