INCUBATION COMPLEX FOR INCUBATION OF CAVIAR AND PRODUCTION OF FINGERLINGS OF SALMON FISH SPECIES Russian patent published in 2020 - IPC A01K61/00 

FIELD: fishing and fish farming.

SUBSTANCE: incubation system includes a body with a solid bottom, forming a pool area, a cover, an incubation substrate, assembled into cassettes incubation trays with transversally located perforated grooves for filling caviar in them, a pipeline for supplying water to the incubation trays and an outlet for larval exit. Cassettes of incubation trays are installed in frame frames. Each cartridge from above is provided with a cover, on one side with a water distribution chamber, which supplies water into incubation trays, and on the other side - outlet for larval exit. Water distribution chamber and outlet are made in the form of truncated pyramids, with taper angle from 45° to 85°, with bases installed in grooves of cassettes, and branch pipes on section side. Inner cavities of water distribution chamber and outlet with nipples from inside are equipped with guide plates, number of which corresponds to number of incubation trays in cassette. Distance between guide plates corresponds to height of incubation tray. Each incubation tray on the side of water supply and on the side of the larval exit is equipped with a net. Water supply system equipped with control valves is connected through the internal system of pipelines to water-distributing chambers of cassettes and water-distributing reservoir located on the internal side wall of the casing in its upper part connected by internal pipelines with upper and bottom sprayers. In the housing bottom a spillway is fixed, in the form of a pipe bend, the upper end of which is located inside the housing at the level of the upper boundary of the water surface. Spillway is secured in the spillway to prevent ingress of fry into the spillway.

EFFECT: invention provides higher efficiency of incubation complex.
