Semiintensive capr (Cyprinus carpio, L) production: Type of sustainable fishery

Abstract

Semiintensive carp production is based on two sources of food for fish proteins that are present in live food and carbohydrates that are provided from additional feeds. By consumption of secondary producers (zooplankton and bottom fauna) nutrients, main causer of water ecosystem eutrophication (phosphorus and nitrogen) is utilized. Unused nutrients (inorganic or organic compounds) are settled at the pond's bottom and through application of agrotechnical measures (natural drainage, winter killing, disking) fertility of the pond's bottom is increased. Semiintensive carp production based on live food as the main protein source fits into the concept of sustainable agriculture.
