ABSTRACT
The breeding of fish undertaken for pond culture is extremely important in the further development of pond fisheries. The methods of breeding in pond pisciculture are, in principle, identical to those in other fields of animal husbandry. Breeding in pond fisheries involves a complex of organizational and fish-rearing measures directed toward the improvement of the hereditary qualities of the fish and an increment in the productivity of the ponds. A number of methods are followed in pond fisheries for interbreed, intraspecific, interspecific, and intergeneric crossing for the purpose of obtaining breeds better adapted to the conditions of definite zones. Fishes from the sturgeon family have rarely been undertaken for pond culture. All the forms of breeding work are closely interrelated and directed toward the main objective—improving the stocks of commercial farms and ensuring a higher output of fish. Productivity, constitutional strength, viability, and transmission of valuable traits to the progeny are primary in achieving the main objective.
