Problems solved by technology

At present, in the freshwater aquaculture industry of Penaeus vannamei, it is generally necessary to manually excavate special culture ponds, and the construction specifications of the culture ponds have certain requirements, and sometimes even destroy the existing state of high-quality land such as tidal wetlands and mangroves. The economic benefit has been improved to a certain extent, but it has certain damage to the natural environment, increases the cost of breeding, and has certain limitations in promotion.

Embodiment 1

[0018] A greenhouse high-efficiency circulation culture method of Penaeus vannamei is characterized in that it comprises the following steps:

[0019] (1) Set up a greenhouse for rice and shrimp breeding: the breeding base adopts saline-alkali ponds in a high-density greenhouse intensive cultivation mode. The area of ​​each pond is 5 mu, and the water depth is 0.5m. The plastic greenhouse with a steel frame structure is built on it. Independent circulating water channel, each pond in the base has independent and unimpeded water intake; water is supplied from one end of the pond and drained from the other end of the circulating water system, and the water intake is equipped with an aeration power of 1 kW / mu;

[0020] (2) Preparations before stocking of Penaeus vannamei: ① Pond disinfection: use hydrogen peroxide to disinfect the pond; apply 20 kg per mu, add water and sprinkle the whole pond; ② Pond water intake: 5 days after the pond is sterilized, 5 days before the shrimp seed...

Abstract

The invention discloses a penaeus monodon greenhouse high-efficiency cycle breeding method which includes the steps of breeding greenhouse building, preparation before penaeus monodon stocking, shrimpseed stocking, feeding management, water quality management and the like. Compound microbial agents are prepared, advantageous microbial communities are formed in water, and water quality pollution is reduced. The method is simple and applicable in technology, low in cost input and high in operability, the breeding risk of penaeus monodons is reduced, and diseases are decreased. Recycling of water in a greenhouse is improved, water eutrophication caused by massive application of feed is greatly improved, water change frequency is decreased, the appetite of the penaeus monodons can be improved, and the digestion and use ratio of the feed is increased.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a high-efficiency circulation culture method for Penaeus vannamei in a greenhouse. Background technique [0002] Penaeus vannamei, the commercial name of Penaeus vannamei in my country, is called Jiwei shrimp. Penaeus vannamei is a euryalline and tropical shrimp species. It has thin shell and fat body, fresh and tender meat, high meat yield (65%), strong disease resistance, fast growth rate, It is rich in nutrition and other advantages. It is native to the waters of the Pacific coast of the Americas. It is recognized as one of the three shrimp species with the highest yield of farmed shrimp in the world today. It was introduced in my country in 1988 and is mainly cultured in coastal saline waters. The culture of Penaeus vannamei has developed from coastal areas to inland areas, and the farming models are also diversified. Winter shed farming in coastal areas, inland pure freshwater soil...
