Problems solved by technology

However, a large number of water changes and drainage will bring the following problems: (1) a large amount of feces and other metabolic wastes pollute the environment; (2) frequent water changes intensify the exchange of pathogenic bacteria; (3) the cost of water changes and drainage is very high
The high cost of the recirculating aquaculture model limits its development, while the biofloc culture model of Penaeus vannamei is still in the experimental stage and has not yet been widely promoted

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

1. Specific examples

[0037] A green and high-yield culture method of Penaeus vannamei comprising the following steps:

[0038](1) After disinfecting, soaking and rinsing with clean water before use, the breeding tank is injected into the breeding water with a density of 2×10 5 Algae cells / ml of cultured Chaetoceros, after 3 to 5 days, you can put Penaeus vannamei shrimp seedlings, the initial size is 1~3g / tail, and the stocking density is 180 fish / square meter. 5 days;

[0039] (2) Feed feed and glucose three times a day in the morning, noon, and evening. The daily feed amount is 4% to 7% of the total weight of the prawns. The carbon-nitrogen ratio of the input feed and glucose raw materials is controlled to be 10:1. The quantity calculation formula is: ΔCH=(C / N×N Feed -C Feed ) / C% ΔCH ; where ΔCH is the amount of glucose added, Feed is...

Abstract

The invention discloses an environment-friendly and high-yield breeding method for penaeus vannamei boone. The method is characterized by comprising the steps of previous-breeding preparation, culture of chaetoceros, adding of a carbon source, feeding and management, water quality monitoring and the like; before breeding, favorable chaetoceros is added to occupy an ecological niche; during breeding, the input ratio of feed to glucose is regulated, heterotrophic bacteria can be stimulated to absorb nitrogen and phosphorus metabolic waste for mass propagation, and then the function of water purification is achieved; by the adoption of a special siphon dirt collection device with an excellent dirt discharge effect, the method enables the water change frequency to be reduced to one time every seven days, and the water change volume is only 5%. The method has the advantages of being simple and controllable, remarkably reducing the feed conversion rate and water change cost and greatly increasing the yield and survival rate of the penaeus vannamei boone, thereby having good biological and economic benefits.

Description

technical field [0001] The invention relates to the cultivation of Penaeus vannamei, in particular to a green and high-yield cultivation method of Penaeus vannamei. Background technique [0002] Shrimp farming plays an important role in the aquaculture industry, making a huge contribution to global food supply and economic growth. With the breakthrough of the breeding problem of Penaeus vannamei, Penaeus vannamei has gradually become the main species of mariculture in my country due to its fast growth, high yield, and strong adaptability. With the rapid development of the shrimp farming industry, the low-yield and low-efficiency traditional farming model can no longer meet the needs of the society. The high-density intensive and factory farming model will eventually replace the traditional farming model and become the future development trend. However, in a high-density breeding system, due to the discharge of a large amount of residual bait and feces into the breeding wate...
