Ponds or Jodhs as they are called up north belong to the Village panchayat (governing body). Up here they are basically leased out for 3,5 or 7 years. An acre size pond cost about Rs 10,000 to Rs 25,000 depending upon the quality of water. Ponds that are away from the main village and that are not polluted by the filth are more expensive. These are stocked with RCC (Rahu, catla and common carp). Ponds near or in the middle of villages are cheaper and are stocked with mangur (Hybrid catfish).
Unfortunately there is a fish mafia that controls the auction of these ponds and only their guys get them. This mafia also control the price of the fish. I met one guy who had leased out over 200 such ponds all over the north. considering that the average income from an acre size pond is about Rs 50,000/- this guy is swimming (sorry for the pun) in money.
