Název v původním jazyce

Zooplankton ecology in common carp ponds

Popis výsledku v původním jazyce

Common carp, Cyprinus carpio, aquaculture is performed almost exclusively in earth ponds to benefit from the natural resources for fish growth and development. Since zooplankton organisms are important components in these freshwater aquatic habitats, the aim of this chapter is to present a review about the relevance of zooplankton and its interactions with cultured carp and carp pond environment. Zooplankton constitute one of the major protein sources in carp diet with varying importance depending on the availability (density, biomass, composition and size structure), fish age, season and environmental variables. On the other hand, as carp are size-selective predators, they can strongly modify composition and structure of zooplankton communities, impeding the presence of vulnerable taxa which leads to increasing abundance of zooplankton taxa that can avoid predation. The strength of the predation pressure is also related to pond management measures, depending on parameters such as fish density, supplementary feeding or fertilization (manuring). In addition, zooplankton community dynamics take placevary along the whole growing season as a result of carp body size and total biomass increase. On the other hand, zZooplankton and its resting stages may also be affected by bioturbation caused by carp searching for benthic food organisms in pond sediments. Finally, the position of zooplankton organisms in intermediate levels of pond food chain predestines them to act as good indicators of water quality, especially with respect to eutrophication processes that are becoming steadily more common in carp ponds.
