Zusammenfassung: | The invention relates to the technical field of aquaculture, and specifically relates to an ecological silvery pomfret fry breeding method. The ecological silvery pomfret fry breeding method specifically comprises the following steps: collecting fertilized eggs; carrying out hatching; rearing fries; and carrying out transitional cultivation with an artificial feed. Water exchange quantity and sewage suction rate are reduced in virtue of addition of probiotics and a living algae solution into the water in cooperation with adoption of a reasonable natural bait feeding way, so that a stable environment is provided for growth and development of the silver pomfret fries; and thus, mortality rate of the fries in an early stage of breeding is greatly reduced. Moreover, the probiotics are used incooperation with the natural baits in a later stage of breeding so as to improve adaptability of silvery pomfret juveniles to artificial baits, so that juvenile elimination rate is reduced in the stage with production cost de |
