TO ENHANCE THE FISH PRODUCTION BY CONTROLLING THE WATER pH IN CARP CULTURE POND BY USING THE BANANA TRUNKS

This aquaculture practice is based on "indigenous technical knowledge" to control pH in carp culture ponds.

Production is mainly dependent on water quality of the culture pond. pH is one of the important water parameters which regulate the carp production and its value may increase or decrease in pond due to various pond conditions. Higher pH can be reduced by keeping banana trunks/stumps in ponds for 3-4 days.

Plenty of banana trunks are available at banana gardens for which farmers do not incur any cost. Banana trunks weighting 1.5-2 ton/ha are released in pond water having pH on higher side. Initially banana trunk pieces float on water surface and slowly due to absorption of water, settle down in the pond.

Result: During this process, the pH of the water reduces and reaches optimum levels. Afterward, these banana trunks remove manually. Due to this process, there are no other effects/alterations of other water parameters.
