The invention relates to a directional hybridization propagation method of Ictalurus punctatuses. The method mainly comprises the following steps: step 1, the Ictalurus punctatuses are put in a copulatory device, and brightness and noise of the copulatory device are controlled; and step 2, laid eggs are put in single hatching troughs for hatching so as to obtain ideal Ictalurus punctatus fries. The invention is beneficial to improve the quality of offspring and prevent a degeneration phenomenon due to close propagation from generating.
