pH of fish pond water.

 

pH value in the waters in nature that ranges from 4 - 9.

 

Water pH affects water fertility because the pH value affects the life of microorganisms.

 

pH values ​​will affect a number of aquatic biology

 

pH of 6-6.5 plankton and benthos slightly decreased

 

pH of 5.5-6.0 a decrease in the diversity of plankton and benthos. Filamentous green algae begin to appear in the litoral zone.


pH 5-5.5 Decreasing diversity and number of different types of plankton, and benthos getting bigger, more filamentous green algae, the nitrification process will be inhibited. there was a decrease in total abundance and zooplankton and benthic biomass.

 

pH 4.5 - 5 Decreasing diversity and number of different types of plankton. the greater the bentos, the more filamentous green algae, the nitrification process will be inhibited. Decrease in total abundance and zooplankton and benthic biomass.

 

in general most aquatic biota like pH values ​​around 7 - 8.5.

 

 

pH value of pond water to fish cultivation :

 

pH <4.5 fish pond water is toxic for cultivated fish (acidic pH)

 

pH 5 - 6.5 The growth rate of fish will be inhibited and fish will be very sensitive to bacteria and parasites

 

pH 6-9 in fish that are cultivated, fish will experience good growth (optimal)

 

pH> 9 fish growth rate will be inhibited
