Zusammenfassung: | The invention provides an artificial breeding method of Epinephelus coioides, which comprises the following steps: S1, treatment of a breeding pond: constructing the Epinephelus coioides breeding pond with the depth of 1.2-1.4 m, disinfecting with quicklime, exposing for 2-4 days, injecting seawater and airing, adjusting the water temperature to 25-27 DEG C, the dissolved oxygen to 5.5-6.5 mg/L, the PH to 6-7 and the salinity to 24-26, maintaining microflow and increasing oxygen, planting aquatic plants in the breeding pond, seawater is replaced once every 9-11 days, and a water quality conditioner is sprayed on the water surface every 15-20 days; s2, fish fry putting: putting 160-200 epinephelus coioides per square meter; the feed is fed, the feeding amount is 2%-3% of the body weight of the epinephelus coioides, after two months, the feeding amount is increased to 5%-7% of the body weight of the epinephelus coioides, and the epinephelus coioides are fed 2-4 times every day. According to the breeding method, |
