Embodiment 1

[0038] The method for cultivating Litopenaeus vannamei outdoor water body ecological seedlings, the specific steps are as follows:

[0039] (1) The water in the nursery pool is first treated with sand filtration, chlorine disinfection, neutralization, and water transfer, and the bacterial phase of the pool water is adjusted before the larvae are released;

[0040] (2) Put the high-quality nauplii according to 80,000 / m 3 density into the nursery pond water;

[0041] (3) Before the nauplii start to turn into zoan larvae, insert Thalassira into the water of the nursery pond, and at the same time insert the rotifers into the water of the nursery pond;

[0042] (4) In the stage of flea-like larvae, adjust the intensity of light and the amount of algae nutrient added to keep the density of thalassira at 20,000 cells / ml without aging, and the density of rotifers at 5 cells / ml. If the density of rotifers is found to decrease , add exogenously.

[0043] (5) In the larval stage of my...

Embodiment 2

[0048] The method for cultivating Litopenaeus vannamei outdoor water body ecological seedlings, the specific steps are as follows:

[0049] (1) The water in the nursery pool is first treated with sand filtration, chlorine disinfection, neutralization, and water transfer, and the bacterial phase of the pool water is adjusted before the larvae are released;

[0050] (2) The high-quality nauplii should be 100,000 / m 3 density into the nursery pond water;

[0051] (3) Before the nauplii start to turn into zoan larvae, insert the high-quality and non-polluting Thalassiosira into the nursery pond water at a density of 8000cell / ml, and at the same time, insert the high-quality and non-polluting rotifers at a density of 10 cells / ml Access to nursery pond water.

[0052] (4) In the stage of flea-like larvae, adjust the intensity of light and the amount of algae nutrient added to keep the density of thalassira at 40,000 cells / ml without aging, and the density of rotifers at 20 cells / ml...

Embodiment 3

[0058] The method for cultivating Litopenaeus vannamei outdoor water body ecological seedlings, the specific steps are as follows:

[0059] (1) The water in the nursery pool is first treated with sand filtration, chlorine disinfection, neutralization, and water transfer, and the bacterial phase of the pool water is adjusted before the larvae are released;

[0060] (2) Use 90,000 high-quality nauplii / m 3 density into the nursery pond water;

[0061] (3) Before the nauplii start to turn into zoan larvae, put the high-quality and non-polluted Thalassiosira into the nursery pond water at a density of 7000cell / ml, and at the same time, put the high-quality and non-polluting rotifers at a density of 8 cells / ml Access to nursery pond water.

[0062] (4) In the stage of zodiac larvae, adjust the intensity of light to 3000lux; the amount of nutrient salt added is 25g of sodium bicarbonate, 40g of sodium nitrate, 4g of potassium dihydrogen phosphate, 80g of EDTA, and 4g of sodium sili...

Abstract

The invention provides an ecological method for breeding young shrimps of litopenaeus vannamei in outdoor water. The method is characterized in that an indoor cement floor is changed into an outdoor cement floor, wherein the inoculation density of algae is controlled to be 5000-8000cell / ml; the inoculation time is controlled to the time before nauplii begin to be changed into zoea under the inoculation density; the synchronization between growth and propagation of the algae and requirements of an ecological system on the density of the algae is ensured; an inoculation density of rotifers is 5-10 / ml, and the inoculation time is the time before the nauplii begin to be changed into the zoea, thereby ensuring that the growth and propagation of the rotifers are e synchronous with the requirements of the young shrimps; the inoculation time of artemia is acanthosoma; the water transparency is retained at 80-120cm; the artemia has the effect of purifying the water; the content of ammonia nitrogen in the overall water is smaller than 0.2, and the content of nitrite is smaller than 0.02; the food intake of the young shrimps and the rotifers are not affected. Through the balance control on a young shrimp rearing water ecological system in the whole production process, the young shrimps take endogenous high-quality natural baits as the major food all the time; the cultured young shrimps of the litopenaeus vannamei are excellent in nutrition, healthy and high in quality.

Description

technical field [0001] The invention relates to aquaculture industry, in particular to an ecological seedling raising method of Litopenaeus vannamei in outdoor water body. Background technique [0002] Since the reform and opening up, my country's fishery output has increased rapidly. The pace of transformation of the fishery structure from fishing-based to aquaculture-based has been accelerating, and the development of aquaculture has advanced by leaps and bounds. The average annual increase rate of aquatic product output is 16%. Among them, the proportion of aquaculture output in the total fishery output increased from 30% in 1980 to 56% in 1997. It has become the only large fishery country in the world whose aquaculture output exceeds the capture output. [0003] Shrimp is the earliest export-oriented aquaculture species developed after my country's reform and opening up, and it occupies an important position in my country's aquaculture industry. In 2009, the national s...
