Zusammenfassung:	The invention discloses a spring and autumn two-season propagation method for loaches. The method comprises the steps of (1) spring breeding pond preparation; (2) spring parent loach selection; (3) spring parent loach pretreatment; (4) spring spawning incubation; (5) spring temporary rearing; (6) spring nursery pond cultivation enhancing; (7) spring fry releasing into the pond; (8) autumn parent loach selection; (9) autumn parent loach pretreatment; (10) autumn spawning incubation; (11) autumn temporary rearing. The method has the advantages that the loach spring and autumn artificial propagation technology is broken through, 40,000,000 of loach pries are propagated each year, the loach fingerling survival rate reaches 40%, and more than 5 million of high-quality loach fingerlings of the average specification of 1g are cultivated each year.
