Rearing systems
The farming system is based on the principle of recirculating units, with the difference from traditional systems that
... a complete water purification is performed in a closed system
... the flow is controlled in the system: (discharge of substances from the habitat of animals / water change)
... the facility is located outside (no indoor system)
... the system is dependent on the ground (groundwater, existing sand / gravel) = Agriculture
... the animals are not removed from the water before stunning (passive sorting in the system)
... potential pathogens in the influent water are killed
... efficiently by deep oxygen supply in the bypass of the inlet water takes place
... predators and other disturbances have no access to the habitat
... the breeding modules are separated from each other locally and technically

Stress - factor of benefit
-
Stress in fish causes a reduced resistance to diseases, reduced growth, lower fillet firmness, different
product quality.
Stress factors are:
2. low oxygene supply
3. impact of germs
4. incorrect stocking density
5. removal from the water
6. feeding stress
7. different fish in the environment
8. predators
9. other species in the environment
10. different scales in the environment
11. change of temperature
12. change of pH-value
13. algue
14. loss of feed (caging)
15. any sudden change
16. pollution
All stress factors are avoided in the waterfruits system.
