Artificial screening method and device for high-quality population of Silurus asotus

The invention discloses an artificial screening method and device for a high-quality population of Silurus asotus. The high-quality population of the Silurus asotus is screened by utilizing a marine culture resource and device. The artificial screening method comprises the following basic methods and steps: firstly, primarily screening the high-quality population: 1, arranging a screening device;2, checking, cleaning and debugging the screening device; 3, primarily screening and pretreating fish school sources; and 4, primarily screening fish schools; and secondly, finally selecting the high-quality population. Due to the adoption of the artificial screening method, defects existing in a population orientation selection way taking a single character as a selection target are effectively overcome, the quality of the selected high-quality population of the Silurus asotus is fundamentally guaranteed, and therefore, the problem of germplasm degeneration caused by serious lag of current artificial screening and mu
