Presenting the RAS this is really Recirculation that is System this is certainly Giant that is revolutionary Prawn taken to you by eWater. The item this is certainly amazing a thinking this is certainly forward that makes farming that is prawn, sustainable, and much more efficient than previously.
The RAS Recirculation Aquaculture System was created to help to keep a environment this can be certainly prawns which are top-notch never need to change water often. The device works on the managed and technology that is recirculating make sure water is normally clean, well-oxygenated, and healthiest when it comes to prawns. This technology is good for farmers who're looking for a method this is certainly functional is a task that is simple operate and needs upkeep this is certainly low.
The RAS Recirculation Aquaculture System ordinarily a solution that is right those attempting to farm prawns sustainably. The apparatus somewhat decreases the requirement for clean water, and agriculture that is therefore prawn be carried call at places where water is scarce or of inferior. Farmers might also make use of the RAS Recirculation Aquaculture System to boost prawns year-round, long period that is lasting because of the fact climate. Plus, the operational system this is certainly functional the utilization of eco-friendly practices by decreasing the amount this is certainly total of created by the farm.
With all the RAS Recirculation Aquaculture System from eWater, prawn farmers will require to many different benefits. The machine is incredibly efficient, enabling farmers to make greater yields with less input. The item additionally enables better control over water quality as well as heat, helping prawns to develop faster and healthy. The device also minimizes the possibility of conditions and insects, making agriculture this is really prawn and more dependable.
The RAS Recirculation Aquaculture System from eWater is an item this is certainly top-rated has been used by prawn farmers all over the globe. The equipment is easy to include and run, making it a solution that is alternative is right those not used to farming this is certainly prawn those attempting to expand their operations and that can be current. Them also is sold with comprehensive assistance and training from eWater, making farmers that are sure make probably the essential when it comes to system.
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.
