Evaluation of Great Cormorant predation activities (Phalacrocorax carbo sinensis) during the spring and autumn migration to ponds on School´s Piscicapture in Protivín between the years 2009 - 2011 and compensation for damages in accordance to the law No. 115/2000 Coll. I compared the results of self-monitoring with the majority known information from many sources in the literature and confirmed the fact that predation pressure are frequently exposed those ponds which are providing food supply in the form of dense fish stock with an acceptable piece weighing 0.03 to 0.5 kg independently on the size of the pond. Confirmed facts are exposed to the conclusion on today's constantly evolving legislation allowing compensation for damages caused by Great cormorant - Act No. 115/2000 Coll. versus regulations No. 393/2012 Coll. and No. 432/2005 Coll
