Abstract

The invention discloses a method for seedling sugpo prawn, comprising the specific steps of: (1) preparing mixed vaccine of bdellovibro nectophore and liposome; (2) putting mixed vaccine of bdellovibro nectophore in a seedling tank so that the content of bdellovibro nectophore in the sea water reaches as high as 101pfu/mL and aerating for 5-12h; (3) putting the sugpo prawn anuplius at the densityof 60000-120000/m<3>; and (4) and in the seedling process, putting bait regularly and putting the mixed vaccine of bdellovibro nectophore at an interval of five days after putting the larva, obtaining the sugpo prawn seedling when the larva prawn grows to 15 days or all the prawns grow with the length of 1cm above, wherein the concentration of the mixed vaccine of bdellovibro nectophore is 10pfu/mL. The invention can effectively reduce the time for changing water in the seedling process by putting the mixed vaccine of bdellovibro nectophore in the water quality treatment and bait in matching with scientific seedling quality management or even failing to changing water, thereby improving the yield of prawn seedling and enhancing the prawn seedling survival rate and immunity.

Description

technical field [0001] The invention belongs to the technical field of prawn breeding and seedling cultivation, and relates to a method for raising prawn seedlings of Penaeus monodon by using a mixed bacterial solution of bdellovibrio swimming body and brudoloid plastid. Background technique [0002] Commonly known as grass shrimp, Penaeus monodon has a long breeding history in my country and is one of the world's largest high-yielding shrimps. The shrimp has the advantages of fast growth, strong adaptability, miscellaneous food habits, large individual, drought resistance, and easy transportation. It is a rare and precious shrimp that is popular with farmers and consumers. Artificial breeding of Penaeus monodon is a job with high technical difficulty and high profit. In recent years, the water quality in the sea area has been polluted to varying degrees, and the risk of raising Penaeus monodon seedlings is even greater. There are many reasons for the disease of Penaeus mo...
