Embodiment 1

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

[0050] Step 2, stocking shrimp with eggs;

[0051] In the middle and lower reaches of the Yangtze River, between May 20th and June 5th, when the water body temperature reaches 27°C-28°C, the weather is fine, and the egg-bearing shrimp is slowly released along the pond; the stocking amount of the egg-bearing shrimp is 500g / mu;

[0052] Step 3: Cultivate shrimp seedlings;

[0053] Step 4, adult shrimp cultivation;

[0054] Check the output of shrimp seedlings in the pond: On July 5 of the same year, the size of the shrimp seedlings was measured to be over 1.2 cm, and the shrimps entered the stage of adult shrimp culture. At this time, the feeding amount of shrimp seedlings reached 0.6 kg / mu.

Embodiment 2

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

[0057] Step 2, stocking shrimp with eggs;

[0058] In the middle and lower reaches of the Yangtze River, between May 10th and May 15th, when the temperature of the water body reaches 18°C-25°C, the weather is fine, and the egg-bearing shrimp is slowly released along the pond; the stocking amount of the egg-bearing shrimp is 500g / mu;

[0059] Step 3, shrimp fry cultivation;

[0060] Step 4, adult shrimp cultivation;

[0061] Check the output of shrimp seedlings in the pond: on July 3 of the same year, the size of shrimp seedlings was measured to reach 1.2cm or more, and the adult shrimp culture stage was entered. At this time, the feeding amount of shrimp seedlings reached 0.38kg / mu, and shrimp seedlings were not supplemented;

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 plant planting holes;

[0064] Step 2: Egg-bearing shrimps are stocked;

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

[0066] Step 3: Cultivate shrimp seedlings;

[0067] Step 4: Adult shrimp farming:

[0068] Check the output of shrimp seedlings in the pond: on July 6 of the same year, the size of shrimp seedlings was measured to reach 1.2cm or more, and the adult shrimp culture stage was entered. At this time, the feeding amount of shrimp seedlings reached 0.35kg / mu, and shrimp seedlings were not supplemented;

Abstract

The invention discloses a multi-space high-dissolved-oxygen device based on freshwater shrimps and a breeding and culture method thereof, and relates to the technical field of freshwater shrimp breeding. The multi-space high-dissolved-oxygen device comprises a plurality of culture units and an oxygenation device, wherein each culture unit comprises a vertical pipe and a plurality of horizontally arranged freshwater shrimp crawling net structures; a plurality of air outlet holes are formed in each vertical pipe, and the density of the air outlet holes in the lower part of each vertical pipe is larger than that of the air outlet holes in the upper part of each vertical pipe; and the lower end of each vertical pipe is inserted into the bottom of a pond, and the lower part of each vertical pipe communicates with an oxygen outlet of the oxygenation device through a connecting pipe. The breeding and culture method of the multi-space high-dissolved-oxygen device based on the freshwater shrimps comprises the following steps: step 1, mounting of the multi-space high-dissolved-oxygen device; step 2, stocking of egg-carrying shrimps; step 3, young shrimp breeding; and step 4, adult shrimps culture. The multi-space high-dissolved-oxygen device is suitable for the freshwater shrimp culture pond, and by arranging the freshwater shrimp crawling net structures, the culture quantity in the pond is increased; and the oxygenation device is arranged to guarantee the requirement of freshwater shrimp culture for oxygen.

Description

technical field [0001] The invention relates to the field of green shrimp multiplication and breeding technology, in particular to a multi-space high-dissolved oxygen device based on green shrimp and a breeding method thereof. Background technique [0002] Freshwater shrimp scientifically known as giant river prawn, also known as river prawn, has become a famous and precious aquatic product that is widely loved by the people because of its rich nutrition and delicious taste, and it is also an important freshwater cultured shrimp in my country. The living habit of freshwater shrimp is to crawl on the bottom of the pond. In the freshwater shrimp nursery stage, the shrimp seedlings are distributed from the three-dimensional distribution of the whole pond at the beginning to crawling distribution on the bottom of the pond after metamorphosis into juvenile shrimp. Because a large number of freshwater shrimp larvae are all gathered at the bottom of the pond, the space pressure an...
