Zusammenfassung: | The invention discloses a method for improving a siniperca chuatsi fertilized egg hatching rate and a fry uniformity, and belongs to the technical field of siniperca chuatsi breeding. According to themethod, a method of stopping water supply for 20-30 minutes is adopted when half of eggs are hatched during hatching of the siniperca chuatsi eggs, so that a fry hatching rate can be quickly improved, a teratogenesis rate is greatly reduced, and the fry uniformity and an opening ratio are improved.
