Abstract: Abstract: The breeding of Megalonibea fusca in earth pond was adopted the combining method of the indoor high-density breeding first and the cultivation in earth pond afterwards. When the young hatch 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 2.2666667ha bred 5.3 × 105 juveniles which the body length ranged from 9.9 mm to12.6mm. In autumn, the temperature of pond water ranged form 23 to 18.4 ℃, salinity of 13～25, pH 8.3～8.8. After 50 days, 2.868 x 105 fry were harvested with overall length of 35～69mm and average length of 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 with large size could improve.
