Impact of topmouth gudgeon (Pseudorasbora parva) on production of common carp (Cyprinus carpio) - question of natural food structure

Popis výsledku v původním jazyce

Four production fishponds in the Czech Republic were investigated in 2003 and 2004 during a feeding experiment on common carp (Cyprinus carpio). In 2003, topmouth gudgeon (Pseudorasbora parva) was detected in enormous amounts in all of the investigated fishponds. P. parva got into the fishponds spontaneously by water inflow from connecting channels. The objective of this paper is to describe the condition of natural food in the presence of P. parva and its subsequent effect on carp production. The estimation of the population density of P. parva achieved at least 44 kg ha?1 in 2003. In 2004, precautions against P. parva invasion were taken and its presence wasn't recorded during the season. The impact of P. parva on natural food structure was describedin terms of zooplankton and zoobenthos amounts and main fish production parameters. A special focus has been taken on the density of Daphnia genus and chironomid larvae, the most preferred zooplanktonic and zoobenthic groups in feed of P
