The eWater Indoor Intensive RAS Aquaculture System is perfect for prawn farming system. It is an item that is revolutionary provides a sustainable and efficient way to develop prawns in a host that is interior. This system consists of high-quality elements that can come together in order to make a environment that is perfect prawns to flourish.

The eWater Indoor Intensive RAS Aquaculture System is simple to operate and setup. It comes down with clear installation instructions and certainly will be quickly assembled without specialist help. These devices are user-friendly, as well as the settings are really user friendly, rendering it simple for you to definitely operate. The device is totally automated, providing a control that is precise this is certainly crucial to the healthy growth of prawns.

The eWater Indoor Intensive RAS Aquaculture System is energy-efficient, making it a variety that is budget-friendly prawn farmers. This technique recirculates water through a filter this is certainly biological removes impurities and pollutants, decreasing the necessity for regular water modifications. The machine features a energy that is low rate, which makes it an energy-efficient item which will surely help you save well on power expenses.

One of the most significant great things about the eWater Indoor Intensive RAS Aquaculture System is its power to create an environment that is optimal prawn agriculture. A heat is had by the system control mechanism that permits one to keep up using the water this is certainly optimum for prawn development. This will make it much easier to achieve yields which can be optimal even yet in regions with extreme weather conditions.

The machine even offers a mechanism this is certainly feeding dispenses food at precise intervals, making certain your prawns are adequately fed. The machine that is feeding automated, and you may easily adjust the feeding intervals and portions to allow for the prawn's growth stage.

The eWater Indoor Intensive RAS Aquaculture System is made to last, with top-quality materials that may withstand the marine environment that is harsh. The machine calls for maintenance that is minimal features a long lifespan, rendering it an intelligent investment for prawn farmers.

Advantages of Recirculating Aquaculture System (RAS)
1. It can effectively solve the problem of pollution and discharge of traditional aquaculture tail water, save energy and reduce emission, and protect the environment.
2. Not subject to the influence and constraints of the natural environment, such as climate and water quality changes, the aquaculture process is easy to control, and can realise year-round multi-cycle aquaculture.
3. It can reduce the dependence on high-quality aquaculture water source and realise cross-regional aquaculture, northern culture of southern fish and desalination of marine fish.
4. It can effectively isolate diseases and control the invasion of disease sources, reduce the rate of nursery bacteria and
morbidity, and improve quality and efficiency.
5. Controllable aquaculture environment and product growth rate, and predictable aquaculture harvest.
6. Water and land saving, flexible site selection and high utilisation rate of the farm site
7. High-density breeding, occupying less land, greatly increasing the production per unit of breeding area, scale efficiency and economic benefits.
