The invention provides a
starter culture for a biological preparation for inhibiting the growth of vibrios in
shrimp ponds. The
starter culture comprises the following bacterial contents accounting for total
bacteria count: 5 to 15 percent of
bdellovibrio bacteriovorus, 5 to 15 percent of
bdellovibrio starrii, 20 to 40 percent of bacillus, 20 to 40 percent of
lactobacillus and 10 to 30 percent ofrhodotorula benthica. The invention further provides a biological preparation for inhibiting the growth of vibrios in
shrimp ponds and a preparation method thereof, and the biological preparation is mainly prepared by activating the
starter culture to ferment material. According to the biological preparation, by reasonably matching multiple
probiotic agents to ferment the material to prepare the biological preparation, the mutual cooperation between the different strains is utilized to obtain the biological preparation capable of effectively inhibiting the growth of vibrios in the
shrimp ponds, and the preparation method for the preparation is simple, does not have high requirement on equipment, and has high
operability, and the biological preparation can be easily popularized for use in large-scale aquafarms or aquiculture cooperatives.
