Circulating water farming than traditional farming advantages – Aquatic Forum – China Animal Husbandry Website – A useful animal husbandry website
Circulating water farming is a hot industry in recent years, gradually giving people to choose, what exactly what is the advantage of making many colonies?
1, circulating water aquaculture density and breeding cycle advantage comparison
The cultured microbial environment in the circulating water culture system, including water temperature, dissolved oxygen, density, light, etc., all are all affected Artificial regulation, thereby providing a suitable, stable growth environment for farming organisms. The growth rate of cultured organisms is 20% to 100% in the growth rate of circulating water, and the cultured density is 3-5 times the culture breeding. Such as Daxumi is generally 10-15kg / m2, the aquaculture period is 12 months, while the circulating aquaculture density can reach 40-50kg / m2, and the breeding cycle is shortened by 10 months; the survival rate is raised from 50% to 90%.

2, aquaculture energy consumption contrast
The cost of construction and operating energy consumption in circulating water culture work is higher than the water supply. However, the influence of the decurity and breeding cycle is shortened, the unit operating cost of the Circulating water farming is only 7.28 yuan / kg, which is 14.05% compared to the water supply, and the unit operation cost of the river circulating water and winter is more water. Falling at 25.02%. The data is as follows:

Circulating water farming advantage is also reflected in Multiple aspects:
Product quality controllable, farming succession high-work factory cultured from the source to solve the quality of breeding products and cultured in culture, easy to scaleCopying in production and breeding mode, affecting the environment. Food Safety: Through ecological health, it ensures strict control of various breeding products such as seedlings, feed feed, water quality control, microbial flour, and ensuring the healthy growth of breeding products to ensure product quality.
Aquaculture: Closed factory cultured model avoids cultured products and water cross-infections from traditional breeding models, while minimizing climate change, weather disasters on the adverse effects of culture, reducing farming Risk, to ensure the quality of shrimp, thereby improving the shrimp growth rate.
Large-scale production: intensification, factory production method reduces the dependence of breeding products on geographic environment and climate environments, farming bases can flexibly lay out around large and medium-sized cities, with close transport aging and cost Advantage. The annual balanced production can be realized, with the anti-season production supply advantage, to meet the needs of fresh seafood products in different local consumer groups, greatly enhance the breeding benefits.
Environmental impact: The traditional aquaculture method has low output efficiency, large area, contaminated environment and other disadvantages, and difficult to achieve sustainable development. It is characterized by high efficiency, water-saving, fertilizer, and emission of controlled, water-saving, semaphore, and emissions. It is in line with sustainable development requirements.
