Aquasend Customers Review Real-Time Monitoring Benefits
Oxygen is one of the most important assets to each aqua farm. Protecting it is critical. These are quotes taken directly from farmers regarding oxygen.
'Dissolved oxygen is the most critical water quality parameter in warmwater aquaculture. As we feed fish more and more, the dissolved oxygen will drop lower and lower in the early morning hours. The warmer the temperature, the faster it will drop. If we do not run aerators at night, fish will die from low dissolved oxygen in intensively fed ponds, but we don’t want to run aerators when it is not necessary. That’s why it is important to monitor (measure) dissolved oxygen. This can be done manually, with a night oxygen man and a handheld meter who turns on aerators manually as the oxygen drops, or an automated system can be used. Automated oxygen monitoring and control systems can be programmed to turn on aerators at specific set points, thus saving energy.'

'Oxygen and temperature are the two most important statistics that we need in aquaculture. Tilapia is not as sensitive as the other fish but when the oxygen is low in the morning, it may kill the whole tank--it could be just a 100lb of fish for small tank or could be 50,000 lbs of fish or more..... In one of the farm, they lost all fish in the farm, ok before they sleep, all fish dead when they wake up in the morning..... As far as temperature, Tilapia will stop eating when temperature dips below 65 and dead below 55 degrees.'

'Dissolved oxygen (DO) concentration is the primary limiting factor to survival and growth of aquatic animals. Therefore, those of us who cultivate aquatic animals must know the DO in our culture medium. We want to monitor it continuously, because DO can change for the bad rapidly depending on the health of phytoplankton in pond systems, or the mechanical soundness of machines that artificially produce oxygen in culture tanks. Often, mechanical aerators are switched on or off depending on continuously monitored DO.
I use continuous monitoring for 2 primary purposes. One is to automate the switching on and off my mechanical aerators. Second is as a type of insurance against mortality of shrimp from unexpected mortality of phytoplankton that should be producing oxygen during the day.
Temperature directly affects how much oxygen can be contained in water. All aquatic animals have upper and lower limits of temperature for survival, feed consumption, and growth. Knowing the temperature is knowing a key indicator of how the animal should be performing.'
