Abstract: The combining method of the indoor high-density breeding prelarva and the ecological cultivation juvenile fish in earth pond was adopted in the breeding of Megalonibea fusca. When the young larvae hatched was cultivated to the juvenile stage in the room, the fish paste was fertilized for bait. After that, fry in earth ponds was fed with fish paste all the time. The four ponds with a total area of 2.27 hm² bred 53.0×10⁴ juveniles that the body length ranged from 9.9 mm to 12.6 mm. In autumn, the temperature of pond water ranged form 18.4 to 23.0℃, salinity from 13 to 25, pH 8.3~8.8. After 50 day's cultivation, 28.68×10⁴ fries were harvested with overall body length of 35~69 mm and the average was 48 mm, while the survival rate was 54.1%. Using the fish paste, the water was clear, green and stable, the bait food was rich, and the survival rate of larvae put with large size could improve much.
