The invention discloses a yearly artificial propagation method of mandarin fish. With the adoption of an ecological and physiological adjustment method, baby fish of mandarin fish are born every 20-30days, thus shortening propagation period and greatly increasing yearly birth rate. Since baby fish can be utilized frequently, boby fish can breed 9-12 times, thus improving the utilization rate andartificial propagation efficiency of baby fish, reducing the stock of baby fish and the cost used to cultivate baby fish, and increasing the ecnomic benefits by 6 times and above. According to the propagation method disclosed by the invention, the spawning rate, the fertility rate and the hatching rate of baby fish are high; the quality of fry is good; fry reaching sales specifications of 3 cm whole length are obtained after being cultivated for 5-20 days; the economic benefits of farmers are increased; artificial propagation of mandarin fish is no affected or limited by seasons or time; the long-standing problem of early releasing of fry in cold springs and insufficient fry out of season is solved; fry varieties are supplied year in year out; the purpose of balanced production is achieved; and mass production of mandarin fish fry can be facilitated.
