Embodiment 1

[0023] Example 1: Rapidly multiplying Artemia domesticated in a high-temperature and high-salt environment

[0024] (1) Indoor domestication:

[0025] Phase I: To the sterilized area of ​​200m 2 Inject the filtered water with a depth of 80cm into the indoor pond, adjust the salinity of the water to 3°Bé (30‰, about 30g / L brine salinity), and then insert the hatched artemia with a fresh weight of about 3Kg. Larvae, the control water temperature is 28 ℃, every day divides twice in the pond and sprays and feeds the compound bait A of 20g; 2 ratio mixed to get.

[0026] Phase II: After 5 days of cultivation in Phase I, adjust the salinity of the pool water to 9°Bé (90‰, about 90g / L brine salinity), continue to control the water temperature to 28°C, and increase the daily feeding amount of bait A to 60g.

[0027] Stage III: After 6 days of stage II culture, continue to adjust the salinity of the pool water to 13°Bé (140‰, about 140g / L brine salinity), change the temperature of ...

Embodiment 2

[0032] Example 2: Rapidly multiplying Artemia domesticated in a high-temperature and high-salt environment

[0033] Different from Example 1,

[0034] (1) Indoor domestication:

[0035] Phase I: To the sterilized area of ​​200m 2 Inject filtered water with a depth of 80cm into the indoor pond, adjust the salinity of the water to 4°Bé (40‰, about 40g / L brine salinity), and then insert the hatched artemia with a fresh weight of about 5Kg. Larvae, the control water temperature is 30 ℃, every day divides twice in the pond and sprays and feeds the compound bait A of 50g; 3 ratio mixed to get.

[0036] Phase II: After 6 days of cultivation in Phase I, adjust the salinity of the pool water to 10°Bé (100‰, about 100g / L brine salinity), continue to control the water temperature to 30°C, and increase the daily feeding amount of bait A to 100g.

[0037] Stage III: After stage II cultivation for 5 days, continue to adjust the salinity of the pool water to 14°Bé (150‰, about 150g / L br...

Embodiment 3

[0041] Example 3: Rapidly multiplying Artemia domesticated in a high-temperature and high-salt environment

[0042] Different from Example 1,

[0043] (1) Indoor domestication:

[0044] Phase I: To the sterilized area of ​​200m 2 Inject the filtered water with a depth of 90cm into the indoor pond, adjust the salinity of the water to 3°Bé (30‰, about 30g / L brine salinity), and then insert the hatched artemia with a fresh weight of about 5Kg. Larvae, the control water temperature is 30 ℃, every day divides twice in the pond and sprays and feeds the compound bait A of 40g; Mixed at a ratio of 2.5.

[0045] Phase II: After 5 days of cultivation in Phase I, adjust the salinity of the pool water to 10°Bé (100‰, about 100g / L brine salinity), continue to control the water temperature to 30°C, and increase the daily feeding amount of bait A to 80g.

Abstract

The invention provides a fast-proliferating artemia in a high-temperature and high-salt environment and a domestication method thereof. The domestication method feeds the compound bait in stages, gradually strengthens the adaptability of Artemia to the extreme environment of high temperature and high salt, and continuously feeds the compound bait after the domestication is completed, ensuring the protection of Artemia for polyunsaturated fatty acids (EPA). intake, maintain the permeability of Artemia cell membranes, and ensure its ability to absorb nutrients in extreme high-temperature and high-salt environments; thus realizing the brine production pool environment in summer in salt lakes (the upper water temperature is 32-38°C, and the salinity is 15-18°C). °Bé or 160‑190g / L brine salinity) the problem of Artemia proliferation. The artemia rapidly proliferates in the high-temperature and high-salt environment domesticated by the present invention, and can sustain rapid proliferation under the premise of continuous feeding of compound bait, thereby reducing the material cost of purchasing Artemia larvae and the time cost of repeated domestication and cultivation, and is The development of industrialization provides technical support.

Description

technical field [0001] The invention belongs to the field of cultivation, and relates to a method for cultivating Artemia, in particular to a method for multiplying and domesticating Artemia in a high-temperature and high-salt environment. Background technique [0002] Artemia (Brine Shrimp) is also called saltwater Artemia, and Chinese folks are also called salt worms or brine shrimp; it belongs to the phylum Arthropoda, Crustacea, Branchopod, Anocaria, Saltwater Artemia, Artemia (Artemia) . Artemia is rich in protein, complete in amino acid composition, relatively high in fat and polyunsaturated fatty acids, and rich in trace elements and growth factors. Artemia, as a high-quality live bait, is widely used in shrimp, crab, sea fish, freshwater fish and ornamental animal larvae breeding, and is the most widely used biological bait. About 40,000-50,000 tons of fresh Artemia are used for aquatic economic animal breeding in my country every year. So far, there is no substitu...
