The invention relates to a method for artificially breeding a sea horse seeding. The method is to adopt the siphonage to discharge half to two thirds of stale sea water in pool within two or three days after hatching of sea horse, absorb completely sewage on the pool bottom, and add fresh sea water. When water is refreshed, the temperature difference between the stale sea water and refresh sea water is not more than 3 DEG C. The length of the bred seeding body is only between 0.8 and 1 centimeter, and the bred seeding stocking is between 150 and 200 tails per cubic meter. The bred seeding is fed for three times a day, the bait amount cast each time is about 10 to 20 percent of the weight of the sea horse, and the adjustment of water temperature and light, as well as the prevention and treatment of damage work are carried out properly. The method can realize the scale artificial breeding of the sea horse seeding, and has the advantages of low breeding cost, high seeding survival rate and so on.
