The invention discloses a compound
probiotic preparation for breeding
macrobrachium rosenbergii as well as a preparation method and application of the compound
probiotic preparation, and relates to the technical field of microorganisms, the compound
probiotic preparation comprises the following active strains:
Lactococcus gasseri,
Bacillus subtilis and
Nitrobacter winogradski, and the compound probiotic preparation comprises the following active strains:
Lactococcus gasseri,
Bacillus subtilis and
Nitrobacter winogradski, and the compound probiotic preparation comprises the following active strains:
Lactococcus gasseri,
Bacillus subtilis and
Nitrobacter winogradski. Wherein the preservation number of the
lactococcus format is CGMCC (China General
Microbiological Culture Collection Center) No.31024. According to the physiological requirements of different development stages of the Z1-Z4 stage and the Z5-P1 stage of larvae, 2: 1 and 2: 1: 1 bacterial strains are adopted for staged accurate addition respectively, meanwhile,
artificial seawater of a specific formula is matched, baits such as
fairy shrimps and
egg custard are quantitatively fed according to the development stage, key
water quality indexes such as dissolved
oxygen,
ammonia nitrogen and
nitrite in a
water body are strictly regulated and controlled, and the quality of the larvae is improved. A green
seedling raising technical
system integrating probiotic micro-ecological regulation and control, precise
nutrition supply and
water quality management is formed, and finally the effects of improving the
survival rate of larvae, reducing the
metamorphosis rate, promoting growth and development and replacing
antibiotics for use are achieved.
