The present invention discloses a method of improving Japanese
prawn breeding capacity of a pond. The method comprises feeding water, applying
fertilizer, cultivating bentonic organisms, releasing seedlings and harvesting prawns. Before feeding water, a microporous
aeration pipe is laid at the bottom of the pond, and connected with a roots blower. In the culture process, the dissolved
oxygen concentration is detected, and an aerator is turned on regularly to keep the dissolved
oxygen concentration at 3-7mg / L. When releasing seedlings, the
seedling releasing density of the Japanese
prawn is 20000 per mu. After the basic feed cultivate at the earlier stage in the pond is finished off, high-quality
protein compound feed is thrown in the pond according to the growth stage of the Japanese
prawn. When the Japanese prawn grows to 2.8-3.2cm, 4.2-4.8cm long acanthogobius hasta is released by 35-45 per mu. According to the present invention, a high-density Japanese prawn breeding technique under the condition of pond culture in
North China region, and the pond
seedling releasing density of Japanese prawn is increased from traditional 10000 per mu to 20000 per mu. Besides, the
survival rate of the Japanese prawn is guaranteed, and increased breeding yield, reduced breeding cost and
disease control are achieved. In short, both yield and efficiency are increased.
