A system for studying the living environment of freshwater living fish

When breeding live fish, such as carp, crucian carp, grass carp and storing them in intermediate warehouses, problems with the quality of the environment sometimes arise. In this case, in order to reduce mortality, it is necessary to take measures related to ensuring a quality environment. In the work, a mobile system for measuring basic indicators of water (pH, dissolved oxygen, temperature) is proposed. With the system was made measurements in two rivers and one dam in which fish are grown. It was found that at this stage, the environment conditions are within normal limits.
