The invention relates to fish breeding, namely to an installation for incubation of spawn and storage of fish prelarvae.The installation, according to the invention, comprises a chamber (1) for incubation with a cover (2) , a water supply funnel (6), placed on the cover (2) of the chamber (1), a filter (7) fixed in the lower part of the funnel (6), a water drainage system, consisting of a water drainage nozzle (8) disposed horizontally in the upper part of the side wall of the chamber (1) and equipped with a barrage net (9), and a chamber balancing system, consisting of two rectangular capacities (10, 14) symmetrically centered on the side walls of the chamber (1), one (10) being made with the possibility of filling with water through the upper part and another (14) connected to the system of water drainage from the chamber. At the same time, each capacity (10, 14) is made with conical bottom (11, 15), equipped with a conical valve (12, 16) connected to a rod (13, 17), which passes through a central opening of the conical bottom (11, 15). The installation further comprises a support tube (18), disposed from the outside along the transverse axis of the chamber (1) bottom, equipped with semi-circular supports (19) disposed coaxially on the support tube (18), and two additional supports (20) disposed symmetrically relative to the tube (18).The result is to increase the fish breeding efficiency and the number of obtained viable young fishes. Invenţia se referă la piscicultură, şi anume la o instalaţie pentru incubarea icrelor şi stocarea prelarvelor de peşte.Instalaţia, conform invenţiei, include o cameră (1) pentru incubare cu capac (2), o pâlnie (6) pentru alimentarea cu apă, amplasată pe capacul (2) camerei (1), un filtru (7) fixat în partea de jos a pâlniei (6), un sistem de evacuare a apei, constituit dintr-un racord (8) de evacuare a apei amplasat orizontal în partea superioară a peretelui lateral al camerei (1) şi dotat cu o plasă (9) de protecţie, precum şi un sistem de balansare a camerei, constituit din două recipiente (10, 14) dreptunghiulare centrate simetric pe pereţii laterali ai camerei (1), unul (10) fiind executat cu posibilitatea umplerii cu apă prin partea superioară, iar celălalt (14) conectat cu sistemul de evacuare a apei din cameră. Totodată, fiecare recipient (10, 14) este executat cu fund conic (11, 15), dotat cu o supapă conică (12, 16) unită cu o tijă (13, 17), care trece printr-un orificiu central al fundului conic (11, 15). Instalaţia mai include un tub (18) de suport, amplasat din exterior de-a lungul axei transversale a fundului camerei (1), dotat cu suporturi semicirculare (19) amplasate coaxial pe tubul (18) de suport, precum şi două suporturi (20) suplimentare amplasate simetric faţă de tub (18).Rezultatul constă în sporirea eficacităţii reproducerii peştilor şi a cantităţii de puiet viabil obţinut.
