Some commonly used water quality parameters and testing methods in Aquaculture

August 9, 2023

Aquaculture water quality testing is essential. It can help aquaculture personnel understand the environmental conditions of the aquaculture water body, discover and solve possible problems in time, and ensure the health and stability of the aquaculture water body. The following are some commonly used water quality parameters and testing methods:


pH value: Use a pH tester or test paper to quickly measure the acidity and alkalinity of the water body. Generally speaking, the suitable pH range for fish is 6.5-8.5.


Dissolved Oxygen (DO): Fish need sufficient oxygen to breathe, and a dissolved oxygen meter can be used to measure the dissolved oxygen content in water. The appropriate dissolved oxygen concentration is usually between 5-8 mg/L.

Ammonia nitrogen: Ammonia nitrogen is one of the most common harmful substances in water bodies, which can be detected by ammonia nitrogen test paper or water quality analysis instruments. The appropriate concentration of ammonia nitrogen should be less than 0.02 mg/L.


Nitrite and Nitrate: These are two other harmful substances in water bodies and their concentrations need to be checked regularly. You can use a water analyzer to test for nitrite and nitrate levels.


In addition to the above parameters, other water quality parameters need to be tested, such as water temperature, salinity, conductivity, etc. Depending on the specific farming method and fish species, specific water quality requirements may exist.


To conduct accurate water quality testing, you can choose to purchase high-quality water quality testing instruments and reagents and follow the operating instructions provided by the manufacturer. In addition, standardized breeding management and appropriate feeding methods can also maintain a good water quality environment.
