METHOD OF VIGOROUS FISH SEEDING PRODUCTION

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to lake fish breeding. Method involves preparation of lake to seeding by valuable fish species. During the first year the lake is stocked with large seeding. In winter under the conditions of oxygen shortage all grown fish and local stunted fish together are concentrated in the aeration zone of a turboaerator and attracted to the concomitant water body. Afterwards all fishes are seined by total fishing method with the help of a fine sweep net or are firstly seined by a large-meshed net and then by a fine-meshed net. In the following years larvae are let out to the lake in spring for growing. The larvae are grown up to underyearlings, concentrated in the aeration zone of the turboaerator and attracted to the concomitant water body where they are kept until ice is melted in finishing water bodies. The fishes are fished from the concomitant water body by batches as far as live-fish vehicles come and are relocated into finishing water bodies.;EFFECT: invention ensures improvement of commercial fish breeding efficiency.;3 cl, 1 dwg, 2 ex
