Method for improving sebastiscus marmoratus fry cultivation survival rate in northern area

The invention discloses a method for increasing the breeding survival rate of sebastiscus marmoratus seedlings in northern areas, and relates to the technical field of aquaculture. The method comprises the following specific cultivation operations: construction of fry cultivation infrastructures, optimal cultivation of parent fishes, a process of pond arrangement and farrowing, selection treatment and feeding of baits, disease prevention and control, regulation and control of cultivation water quality in breeding management, bottom suction and decontamination, pond separation and fry screening and the like. According to the method for improving the breeding survival rate of the sebastiscus marmoratus fries in the northern area, the opening rate of the first larva fish of the sebastiscus marmoratus reaches 95% or above, the larva breeding survival rate reaches 92% or above, high-quality fries with the average overall length of 4 cm can be obtained after three months of breeding, the breeding survival rate of t
