ЭКОНОМИЧЕСКАЯ ЭФФЕКТИВНОСТЬ ВЫРАЩИВАНИЯ СЕГОЛЕТОК КАРПА И РАСТИТЕЛЬНОЯДНЫХ РЫБ В ПРУДОВОМ ХОЗЯЙСТВЕ АЛМАТИНСКОЙ ОБЛАСТИ КАЗАХСТАНА

Abstract

The article highlights the problem of commercial breeding of carp yearlings ( Cyprinus carpio ) in the fish farms in the south part of Kazakhstan with the purpose of the industrial cycle reduction. There is given a brief description of the experience in growing carp yearlings as a commercial fish product (pilot variant) and fish seeds (control variant) in polyculture with herbivorous fishes (grass carp ( Ctenopharyngodon idella ) and silver carp ( Hypophthalmichthys molitrix )) using various technological schemes, in the fish farms in the Almaty region. There are presented initial data on the stocking of experimental and control ponds by young adults; data on the final harvest of experimental ponds, including the average weight of commercial yearlings of carp and seeds of silver carp in the experimental version, and carp seeds and herbivorous fish in the control version; the fish productivity of ponds according to each polycultural specimen and the costs of artificial feed. Calculations are given on economic efficiency of growing yearlings in pilot and control variants, the profitability of growing commercial carp in the pilot version and the cost of fish seeds for carp and herbivorous fish in the control version. The most economically efficient technological schemes for growing yearlings of carp and herbivorous fish species in fish farms with channel ponds in the south of Kazakhstan have been proposed. The article shows that breeding carp yearlings is well-founded It presents the ways of planning of breeding the fish-seeds of carp and herbivorous fishes in fish-hatcheries and pond farms of Kazakhstan in modern economic conditions.
