Problems solved by technology

At present, domestic and foreign Litopenaeus vannamei seedlings are raised in indoor factories. This method requires the construction of factory-like seedling rooms with cement seedling ponds equipped with bait cultivation, water supply, gas supply, electricity, etc. system, the seedling raising conditions are complicated and the cost is high
In addition, because seedlings are raised in indoor cement ponds, a large amount of artificial feed is fed in a limited water body, coupled with the high density of larvae, it is difficult for the nutrition and water environment to meet the physiological and ecological needs of the growth and development of shrimp seedlings.
It is difficult to guarantee the quality of shrimp seedlings cultivated in a factory

Embodiment 1

[0014] Simulate the natural environment, cultivate high-quality healthy shrimp seedlings at low cost and imitate ecology:

[0015] Choose a seawater culture nursery pond with a natural water temperature stable at 28°C (both ordinary earthen ponds and high-level ponds are acceptable), use medicine to clear the pond to kill harmful organisms, and carry out water disinfection treatment after entering the water. Litopenaeus larvae are put in, and the stocking density is 10,000 fish / m 2 , after the larvae are put in, the rotifers in the rotifer cultivation pond are pumped out and filtered with a 200-mesh sieve, and after being concentrated, they are fed into the nursery pond; the feeding density of rotifers is 5000 / L, and the rotation Insect density; when the number of rotifers is insufficient, add appropriate amount of artificial bait, artificial bait is shrimp chips, soybean milk and yeast. The rotifers are fed with single-cell algae, and the water in the single-cell algae pool ...

Embodiment 2

[0018] The suitable area of ​​the nursery pond is 1-5 mu, and the water depth is 1-1.5 meters. If the aeration facilities (bottom aeration and aeration machine) are installed, the effect will be better. The area of ​​the single cell algae pond is preferably 1-3 mu, and the water depth is about 1 meter; the area of ​​the rotifer cultivation pond is 1-5 mu, and the water depth is 1-1.5 meters.

[0019] Put Litopenaeus vannamei nauplii in the nursery pond, the natural water temperature of the nursery is 35°C, and the stocking density is 100,000 fish / m 2 , after the larvae are released, the rotifers are fed. The rotifers in the rotifer cultivation pool were pumped out circularly and filtered with a 200-mesh sieve, and fed to the nursery pond after concentration; the rotifer feeding density was 10,000 / L, and the rotifer density was maintained; When the number of worms is insufficient, add an appropriate amount of artificial bait, which is shrimp chips and yeast. The rotifers are ...

Embodiment 3

[0022] The difference from Example 1 is:

[0023] The natural water temperature for nursery is 30°C, and the stocking density of Litopenaeus vannamei nauplii is 50,000 / m 2 ; The rotifers stocking density is 8000 / L.

[0024] Example 3

[0025] The difference from Example 1 is:

[0026] The natural water temperature for seedling cultivation is 30°C, and the stocking density of Litopenaeus vannamei is 50,000 fish / m 2 ; The rotifers stocking density is 8000 / L.

Abstract

The invention relates to the field of aquiculture, in particular to a method for raising young litopeneaus vannamei, which comprises the following steps: naupliuses of litopeneaus vannamei are placed into a young shrimp raising pool, and rotifers and unicellular algae are raised, wherein the placement density of the naupliuses of litopeneaus vannamei is 1-100000 / m<2> and areas of the young shrimp pool, a rotifer raising pool and a unicellular algae raising pool is 1:1:1. The invention keeps water environment stable by utilizing a biological water quality regulating technology, and provides excellent biological baits for the growing development of naupliuses of litopeneaus vannamei during various stages. When the naupliuses of litopeneaus vannamei are raised to young shrimps, the young shrimps are caught by a pulling net according to the production demands. The method is suitable for raising excellent and healthy young shrimps on a large scale according to concrete circumstances with low cost by adopting the invention; moreover, the method is simple, practical and easy to operation and is suitable to raising young litopeneaus vannamei in sea water pools in South China.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a seedling raising method of Litopenaeus vannamei. Background technique [0002] See the "Technical Operation Specifications for Shrimp Nursery Production" formulated by the Ministry of Agriculture and the local standard "Technical Operation Specifications for Litopenaeus vannamei Industrialized Nursery Production" formulated by Guangdong Province. At present, domestic and foreign Litopenaeus vannamei seedlings are raised in indoor factories. This method requires the construction of factory-like seedling rooms with cement seedling ponds equipped with bait cultivation, water supply, gas supply, electricity, etc. system, the seedling raising conditions are complicated and the cost is high. In addition, because seedlings are raised in indoor cement ponds, a large amount of artificial feed is fed in a limited water body, and the density of larvae is high, the nutrition and water environme...
