The invention discloses a sugpo prawn larva breeding method, which comprises the following steps of: (1) preparing bdellovibrio bacteriovorus plasma liquid; (2) pouring the bdellovibrio bacteriovorus plasma liquid into a nursery pond, wherein the bdellovibrio bacteriovorus plasma content of seawater is more than 101pfu/mL and aeration is carried out for 5 to 12h; (3) pouring the nauplius larvae of the sugpo prawns into the nursery pond at the density of 60,000 to 120,000/m<3>; and (4) regularly feeding bait into the nursery pond in a breeding process, and pouring the bdellovibrio bacteriovorus plasma liquid at the concentration of over 10pfu/mL into a nursery pond at an interval of at least 5 days every time after the nauplius larvae are poured into the nursery pond, wherein the young sugpo prawns can be obtained after the prawn larvae have been developed for 15 days or the body lengths of the prawn larvae are more than 1cm. In the invention, by water quality treatment and by pouring the bdellovibrio bacteriovorus plasma liquid into the bait and adopting scientific breeding management, the water exchange times during the breeding process can be effectively reduced and even water is not required to be exchanged, so that the yield of the young prawns is improved and the survival rate and immunity of the young prawns are improved.
