The photo shows a group of small ponds (tanks) of 2×2 meters each. Farmers who own such type of ponds use them for breeding purposes. Usually, these facilities produce and distribute their production of fish seed to fish growers in the same or nearby villages. Bamboo that surrounds tanks provides the support of the structure to which plastic sheets are attached. These ponds are filled by mesin pumps while pond draining is done using plastic pipe. Farmers in Indonesian villages are familiar with this type of ponds.
