The maximum load of organisms that can be cultured in a raceway system depends on the species, and particularly on the size of the species. For trout, stocking rates of 30 to 50 kg/m 3 are normal at the end of a rearing cycle, while for marine species, such as sea bass and sea bream, the achievable load is lower, between 15 and 20 kg/m 3 .
The fishponds of the Třeboň Basin or Třeboň fishpond system (Czech: Třeboňská rybniční soustava) are a collection of over five hundred fish ponds.They were constructed from the 13th century onwards in the Třeboň Basin area of Bohemia, now the South Bohemian Region of the Czech Republic, with most work occurring between the 15th and 16th centuries, and collectively cover ...
The pond is primarily used for fish farming. It is the largest in the world in the category of artificially created bodies of water intended primarily for fish farming. [1] The pond is owned by the Rybářství Třeboň a.s. company, which is the largest producent of freshwater fish in Europe. The largest volume of farmed fish is Eurasian carp. [4]
A 1977 national study found that around 15% of fish ponds were smaller than 1 hectare (2.5 acres), although in total there were less than 1% of all fish pond areas. Over half of fishponds were officially above 5 hectares (12 acres), including 5% which were above 50 hectares (120 acres).

Akers Pond is a 276-acre (1.1 km 2) [1] water body located in Coos County in northern New Hampshire, United States, in the town of Errol. Water from Akers Pond flows via Clear Stream to the Androscoggin River and thence into Maine. The lake is classified as a coldwater fishery, with observed species including rainbow trout and largemouth bass. [2]
Though fish ponds required maintenance to keep them healthy, [1] 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 were carp and pike. From the 14th century onward these fish proved to be a popular feature of artificial fish ponds. [1]
A pond is smaller than a lake [1] and there are no official criteria distinguishing the two, although defining a pond to be less than 5 hectares (12 acres) in area, less than 5 metres (16 ft) in depth and with less than 30% of its area covered by emergent vegetation helps in distinguishing the ecology of ponds from those of lakes and wetlands.
