An idea learnt from various sources being experimented in my backyard. A tarpaulin laid in dug put pond. Quantity of stones, sand spread in the side walls and floor. Rain water during this time of the year helps abundant water.
Fish of different varieties as locally supplied are released. But, seems oxygen level is in short as fishes time and again or frequent prop up.
Now an attempt is made with locally improvised materials and pump.
Actually, it is nothing but recycling of water for generating oxygen which is working, perhaps.
Please enjoy.
