CONSTRUCTION METHOD FOR ARTIFICIAL FISH-BREEDING POND

摘要

FIELD: agriculture, fish breeding. ^ SUBSTANCE: invention concerns fish industry and is aimed at construction of ponds for artificial breeding of valuable fish species. The method involves fish maintenance and cultivation in a defined water area in a pond. A water scoop is arranged in the pond and equipped with fish protection unit and fish offset leading to the defined water area, which is stocked with fish and used for artificial breeding of valuable raptor and plankton-eating fish species. The water area is allocated within effective zone of the water scoop in the course of downstream-migrant fish fry and plankton drift. Downstream of local plankton and fish fry of inferior value from the pond to the water scoop is directed through the defined water area. They are used as forage reserve for valuable raptor and plankton-eating fish. Downstream migration of inferior fish fry and plankton into the water scoop is prevented by the fish protection unit and directed via fish offset back to the water area for further use by the bred fish species. The method allows usage of natural fish fauna and plankton of the pond as high-quality forage reserve and at the same time to scoop water for water consumption needs. ^ EFFECT: manufacturing of fish-breeding pond with the use of natural fish fauna of inferior value and plankton as a high-quality forage reserve. ^ 1 dwg
