Abstract

Inventia se refera la piscicultura, in special laun procedeu de reproducere a crapului. Procedeul de reproducere a crapului include plasarea reproducatorilor intr-un recipient dreptunghiular cu volumul de 0,5 m3 la temperatura apei de 19...20°C, concentratia oxigenului dizolvat in apa de 6...8 mg/l si viteza schimbului de apa de 10...15 l/min, fundul caruia se asterne cu un substrat artificial pentru depunerea icrelor, care imita plantele acvatice de culoare verde sau cafenie. Recipientul se plaseaza in penumbra, fiind supus actiunii razelor solare directe numai la revarsatul zorilor. Stimularea maturarii produselor seminale si depunerii icrelor se efectueaza prin plasarea in comun a reproducatorilor maturati pentru reproducere naturala intr-un recipient, totodata initial se plaseaza 6...7 femele, apoi, peste 12...24 ore, 3...4 masculi, iar dupa intretinerea comuna pe parcursul a 12 ore masculii se separa. Produsele seminale de la reproducatori se extrag manual in rigole individuale, icrele extrase se fecundeaza, se descleie si seincubeaza. Rezultatul inventiei consta in majorarea numarului de femele de la care sunt obtinute icre calitative si in sporirea numarului de larve viabile.The invention relates to fish farming, especially to a process of reproduction of carp. The process of reproduction of the carp includes placing the breeders in a rectangular container with the volume of 0.5 m3 at the water temperature of 19 ... 20 ° C, the oxygen concentration dissolved in water of 6 ... 8 mg / l and the exchange rate of water of 10 ... 15 l / min, the bottom of which is sprayed with an artificial substrate for depositing the eggs, which mimics aquatic plants of green or brown color. The container is placed in the shadows, being subjected to the action of direct sunlight only at dawn. The stimulation of the maturation of the semen products and the deposit of the spawning is carried out by placing the matured breeders for natural reproduction in a container, at the same time initially placing 6 ... 7 females, then, over 12 ... 24 hours, 3 ... 4 males, and after common maintenance for 12 hours the males separate. The seminal products from the breeders are manually extracted into individual streams, the extracted eggs are fertilized, decanted and incubated. The result of the invention consists in increasing the number of females from which qualitative spawns are obtained and in increasing the number of viable larvae.
