Embodiment 1

[0049] Step 1. Install a multi-space high dissolved oxygen device in No. 1 pond, and insert artificial aquatic plants in the aquatic plants planting holes;

[0050] Step 2, stocking of egg-bearing shrimp;

[0051] In the middle and lower reaches of the Yangtze River, between May 20th and June 5th, when the water temperature reached 27°C-28°C in fine weather, egg-bearing shrimps were slowly placed around the pond; the stocking amount of egg-bearing shrimp was 500g / mu;

[0052] Step 3: Cultivation of shrimp fry;

[0053] Step 4, adult shrimp culture;

[0054] Check the output of shrimp fry in the pond: On July 5 of the same year, the size of shrimp fry was measured to reach 1.2cm or more, and it entered the stage of adult shrimp breeding. At this time, the feeding amount of shrimp fry reached 0.6kg / mu.

Embodiment 2

[0056] Step 1. Install a multi-space high dissolved oxygen device in No. 2 pond, and insert artificial aquatic plants in the aquatic plants planting holes;

[0057] Step 2, stocking of egg-bearing shrimp;

[0058] In the middle and lower reaches of the Yangtze River, between May 10th and May 15th, when the water temperature reached 18°C-25°C in fine weather, the egg-bearing shrimps were slowly placed around the pond; the stocking amount of egg-bearing shrimp was 500g / mu;

[0059] Step 3, shrimp fry cultivation;

[0060] Step 4, adult shrimp culture;

[0061] Check the output of shrimp fry in the pond: On July 3 of the same year, the size of shrimp fry was measured to reach 1.2cm or more, and it entered the stage of adult shrimp breeding. At this time, the feeding amount of shrimp fry reached 0.38kg / mu, and no shrimp fry was added;

Embodiment 3

[0063] Step 1: Install a multi-space high dissolved oxygen device in the No. 3 pond, and insert artificial aquatic plants in the aquatic plants planting holes;

[0064] Step 2: Stocking of egg-bearing shrimp;

[0065] In the middle and lower reaches of the Yangtze River, between June 15th and June 20th, when the water temperature reaches 30°C-31°C, slowly put egg-bearing shrimp around the pond; the stocking amount of egg-bearing shrimp is 500g / mu;

[0066] Step 3: Cultivation of shrimp fry;

[0067] Step 4: Adult shrimp farming:

[0068] Check the output of shrimp fry in the pond: On July 6 of the same year, the size of shrimp fry was measured to reach 1.2cm or more, and it entered the stage of adult shrimp breeding. At this time, the feeding amount of shrimp fry reached 0.35kg / mu, and no shrimp fry was added;

Abstract

The invention discloses a green shrimp-based multi-space high-dissolved oxygen device and a breeding method thereof, and relates to the technical field of green shrimp culture. The multi-space high-dissolved oxygen device includes a plurality of breeding units and an oxygenation device; a plurality of horizontally arranged blue shrimp crawling net structures; a plurality of air outlets are arranged on the riser, and the density of the air outlets at the lower part of the riser is greater than that of the upper part of the riser; the lower end of the riser Inserted into the bottom of the pond, the lower part of the standpipe is communicated with the oxygen outlet of the oxygenation device through a connecting pipe; the breeding method of the multi-space high-dissolved oxygen device based on the green shrimp of the present invention includes the following steps: Step 1. Multi-space Installation of the high dissolved oxygen device; step 2, stocking of egg-bearing shrimp; step 3, cultivation of shrimp fry; step 4, cultivation of adult shrimp. The invention is suitable for the green shrimp culturing pond. By setting the green shrimp crawling net structure, the number of cultured in the pond is increased; the oxygen demand for the green shrimp culture is guaranteed by the setting of the oxygen-enhancing device.

Description

technical field [0001] The invention relates to the technical field of prawn seedling propagation and cultivation, in particular to a multi-space high dissolved oxygen device based on prawns and a breeding method thereof. Background technique [0002] The scientific name of the green shrimp, the Japanese giant shrimp, is also known as the river shrimp. Because of its rich nutrition and delicious taste, it has become a precious aquatic product widely loved by the people, and it is also an important freshwater aquaculture shrimp in my country. The life habit of green shrimp is to crawl on the bottom of the pond. In the green shrimp seedling stage, the shrimp seedlings are distributed three-dimensionally from the beginning of the whole pond to the crawling distribution at the bottom of the pond after metamorphosis into juveniles. Because a large number of green shrimp larvae all gathered at the bottom of the pond, the space pressure and survival pressure increased sharply, res...
