It also helps to conserve resources, by determining the correct amount of feed for example.
Aquaculture, is one of the fastest growing food-producing sector. It is responsible for providing 50% of the global supply for the fish we eat. Hence, proper management of aquaculture water quality plays a significant role for the success of aquaculture operations.
There are several key water quality parameters that can each directly affect animals’ health. However, in the complex dynamic aquaculture environment, water quality parameters also influence each other. Thus, maintaining balance in water quality parameters is fundamental for the health and growth of culture organisms.
The use of the latest technology is absolutely essential for modern fish farms if they are to achieve high yields and stay competitive. That is why more and more businesses are relying on aeration with pure oxygen in conjunction with automated feeding systems. For automated feeding systems, feeding is regulated according to the water temperature, oxygen content and carbon dioxide content as well as the turbidity. This prevents overfeeding and hence increased pollution of the tank,
At the same time, however, monitoring these automated systems demands sophisticated measurement technology with reliable, self-monitoring sensors.
Hach® offers lab, portable and online measurement tools for the following parameters:
Ammonium
Oxygen (LDO)
Turbidity
pH
Nitrate
Phosphate
Alongside automated systems, routine monitoring of the water quality is very important also. Many of the substances contained in water are harmful to fish, including nitrate, phosphate, ammonium, nitrite and also heavy metals such as copper.
Intermittent monitoring, using mobile systems in some cases, and photometric testing is therefore advisable.
If fish are transported over long distances, the water quality in the transport tanks also has to be monitored. The oxygen and ammonium concentration is particularly important here.
