Abstract

The present invention relates to the technical field of aquaculture and breeding of seawater fishes, in particular to an industrialized cultivation method for cephalopholis sonnerati fry, comprising the steps of successively subjecting parent fishes of cephalopholis sonnerati to feed domestication and nutrient enrichment at a water temperature of 25-29°C and under a flowing water condition, so as to obtain parent fishes with fully developed gonads, etc. The present invention takes strict measures for fry quality control and infectious disease prevention and control during industrialized workshop cultivation, so as to effectively optimize the growth conditions of fry, thus increasing the growth rate and improves the health conditions and adaptability of fry while reducing the risk of diseases. By means of standardized breeding management and technical means, the growth environment and feeding management of fry can be controlled, thus effectively improving production efficiency. The cultivated cephalopholis sonnerati has the advantages of fast growth rate, high disease resistance, strong vigor, tender and delicious flesh and good market prospects.
