If fish ponds are made of earthen materials they will be imposed to water leaching , if it is linend by tuff materials it will harm the fishes through jamming , what is the best solution according to your expert ?
Earthen pond are the natural environment for growth of fish.So,it is always preferred.
But sometimes, in certain circumstances people resort to various method to safeguard the ponds from leaching.
Dear Ajit Kumar Roy
You are right surely , but our problem is the scarcity of water , so we have to follow the artificial ways to consume water.
thanks a lot
There are two approaches you can use. If you have significant loss due to seepage you can install a hypoline liner and then backfill on top of that. That way your loss to seepage is reuduced to zero and you still have a "soil" pond environment, but this is expensive. If you have good soil and some moderate seepage, which will always be the case, you can reduce seepage by adding bentonite or a similar clay. Bentonite swells when wet and this reudes pore size, reducing seepage loss.
