A fish pond , gold fishpond , is a controlled pond , artificial lake , gold tank That is stocked with fish and is used in aquaculture for fish farming , gold is used for recreational fishing gold ornamental for practical purposes. In the medieval European era it was typical for monasteries and castles (small, partly self-sufficient communities) to have a fish pond.
Records of fish ponds being used in the early ages. “The idealized eighth-century estate of Charlemagne’s capitulary of villi has been artificially maintained, but it is still very rare, even on monastic estates.”  As the middle ages progressed, fish ponds became more common feature of urbanizing environments.  This meant the people who had access to these pastures. However, fish ponds have been difficult to maintain. They have been a marker of power and authority, since they have only been able to maintain them. During the winter, supplying fresh food for a castle has been a constant struggle. Noble had access to meat from deer parks, but this did not supply the needs of all households. Though fish ponds service required by the community to keep ’em healthy,  They Were an elegant way of giving monasteries and noble houses access to fresh fish. Some of the more popular species of fish farmed in fish ponds werecarp and pike . From the 14th century onward this fish is a popular feature of artificial fish stocks. 
Fish ponds are used today in aquaculture. They are common in:
- Europe , especially in the Czech Republic ( Rožmberk Pond , Velké Dářko , Lake Mácha ), where common carp can be kept.
- The Philippines where milkfish , tilapia , crabs, lobsters, tiger shrimp , and other snails can be kept.
- East Asia , especially in Japan with koi , trout , and white crucian carp .
Fish ponds are also being promoted in developing countries . They provide a source of food and income for fish farmers and can also provide irrigation and water for livestock.
