Water silo for fish breeding farms
Worldwide approximately only one third of all fish farming takes place in natural habitats. It means most fish is breed under more or less controlled circumstances. This development is an upward trend line, whilst cost for fishing in open water is increasing, the production of too much forage leads to pollution of the natural habitat and rising demand for fish products. Technically we have the possibilities to control the fish production, with a balance between operational costs and market prices. BUWATEC supplies aquaculture tanks for recirculating aquaculture systems, aquaponics systems and fish farms.
Aquaculture is the collective name for breeding salt and fresh water fish, shellfish, living organisms in water, like algae and samphire. The aquaculture is based on two different systems: open systems and closed systems. The open systems are directly connected with natural water such as fish breeding farms in fish cages or shellfish farming. Nevertheless, this type of breeding leads to damage of the natural environment and pollution of open water. The closed systems are not directly connected with natural water resources. These closed systems are fish breeding farms with tanks, basins and ponds. Very often these type of fish farms are using a recirculation systems whereas breeding water will be treated and re-used as a continues process.
Recirculation systems for fish farms
An essential part of the closed breeding systems is the recirculation circuit. For this specific way of fish breeding, temperature, water use, water quality and use of nutrients will be controlled and optimized. In a water treatment process waste materials will be break down and water can be re-used after this process. The negative risks on the environment will be very limited for fish farms based on recirculation of water in fish water tanks.
BUWATEC supplies water tanks for fish farms
The investment in the traditional concrete aquaculture tanks are low, but very much time consuming and quality depend on local expertise and availability of good quality raw materials. The alternative plastic tanks are limited in capacity, not always suitable for outside use and it isn’t cost efficient in transport. BUWATEC developed open water aquaculture tanks based on our corrugated steel plates in combination with the appropriate liner into a fast to build and flexible, reliable water tank for fish farms. In these fish tanks for aquaculture the breeding of tilapia, eel, trout, carps and salmon takes place all over the world.
The installation of a fish tank in aquaculture
The installation of the fish tank needs locally very limited material and tools. This improve the speed for installation of the breeding tank. The operational costs are limited, because all breeding activities take place on and above ground level. These tanks have a height of approximately 1,50 meter above ground level. These tanks are suitable for export towards the continents of Africa, Asia, South and Middle Americas.
Advantages water tanks for fish farms
- Control fish production, with water tanks, with a perfect balance between operational costs and market prices.
- BUWATEC supplies steel aquaculture fish tanks with diameter up to 30 meters.
- BUWATEC aquaculture systems can be built without a concrete foundation.
- One aquaculture tank can be shipped with limited space – low costs.
- The aquaponic tanks are easy to re-use.
