Reliable oxygen levels in trout farms with LDO
An adequate level of oxygen must be maintained in the water of fish farms. If the level is too low, fish production suffers. Stocking density, feed intake and resistance to disease are just three of the key variables that significantly affect profitability and are directly dependent on the oxygen concentration. Kirsten and Alexander Tautenhahn have run a trout farm in Germany, since 1991. Oxygen levels at the farm have been monitored by HACH LANGE LDO sensors since July 2005. The accuracy of the measurements, also at high concentrations, ensures optimal oxygen transfer even during the night, when there is no flow around the sensors. The rugged sensor and extensive warranty assure reliable long-term operation.
