CHANGES IN LEGISLATION AND THEIR EFFECT ON THE GREAT CORMORANT (Phalacrocorax carbo) POPULATION ....

The great cormorant (Phalacrocorax carbo) is a fast-moving fish hunter. Its nimbleness, tenacity, and hunting prowess make it an unwanted visitor in any country with a long history of pond farming. By hunting, cormorant flocks can wipe out the majority of a pond's population. Wild cormorants in the Czech Republic were so uncommon by the end of the twentieth century that they were classified as an endangered species. The population grew as a result of this protection. However, this growth harmed fish farms and, more importantly, the wild fish population in waterways, leading to state-regulated hunting. Cormorants, both resident and migratory, have become more common in the Czech Republic over time. In this paper, we look at the influence of recent legislative changes on the abundance of this species and the harm it has caused in this central European country over the previous ten years.
