Description
  • ?Top-down? regulation is a widely used term for the phenomenon whereby fish stock is the main controling factor of plankton. This has been regularly observed in Czech fishponds for more than fifty years. However, during the last decade situations have been frequently observed which do not correspond to the concept of the ?top-down? regulation. In this paper, an advanced level of eutrophication, the occurrence of more frequent cyanobacterial blooms and changes in fishery management are discussed as causes of the observed changes in the fishpond plankton.
