Umelý výter Hlavátky Podunajskej (Hucho hucho)

The Danube Salmon (Hucho hucho) is an impressive fish species that belongs to the salmon family and is endemic to the Danube River basin. This majestic predator is one of the largest freshwater fish in Europe, capable of reaching lengths of up to 1.5 meters and weights over 30 kilograms. The Danube Salmon prefers clean, cold waters with a rich substrate, providing ideal conditions for spawning and growth. It is known for its ability to survive in various temperature conditions, but its optimal temperature range for development is between 14 and 16 °C. During the breeding season, which occurs from March to May, it concentrates in areas with fast-flowing water, where it lays eggs on gravel bottoms. The population of Danube Salmon has significantly declined in recent decades, primarily due to water pollution, river regulation, and overfishing. Protecting this species is therefore crucial through sustainable management and measures to restore its natural habitat. In our video, we will look at the artificial spawning of Danube Salmon, which is essential for the restoration and conservation of this endangered species. You will see how this process takes place and what measures are being taken to ensure the future of the Danube Salmon in our rivers.
