Fish pond water quality management, a direct impact on fish farming benefits. The main indicators to measure the quality of fish are as follows. 1. Temperature test Different fish require different water temperature. Silver carp, bighead carp, grass, common carp and bream, etc. The suitable water temperature is 20-30 ° C; tilapia suitable water temperature is 25-34 ° C. Now the market water quality analyzer and dissolved oxygen analyzer, have the function of testing water temperature, water temperature can be measured in different layers in order to take regulation
