What is a Huchen?

The huchen, also known as the Danube salmon or the Hucho hucho, is a freshwater fish that originated in the Danube River in Europe. As fishing for this species became more popular, it was distributed to other parts of Europe and can now be found all over the continent. Huchen are freshwater fish that travel from lakes and slow-moving rivers to stake out their territories for most of their lives. This species of salmon is actually the largest breed of freshwater salmon in the world, and for many years, it was exploited as a food source in Europe. Huchen is also considered a great sport fish, simply because of its massive size and volatile temperament—this has contributed to the dwindling huchen population, and the fish is now considered an endangered species.

This fish has a slim body which is nearly round in the middle. The huchen back tends to be red-brown with almost a gradient effect, with several dark patches which are oddly shaped either like an X or a crescent. These characteristics are not very reminiscent of the North American salmon variety.


During the mating season, the female may lay her eggs in more shallow and still waters. Smaller fish will stay in these waters and feed on other fish eggs, larvae, or insects. As the fish grows, it may move to deeper waters and begin feeding on other fish or even small animals such as mice in the water.

The huchen species is very territorial, and instead of leaving the eggs after mating, a female will guard her nest vigorously. After the incubation period of 16 to 24 days, the eggs will hatch, and then the female may leave her nest. Other than during mating season, the huchen is not considered a social fish.

Conservation efforts are under way to breed huchen in controlled environments, hatch the eggs, and then return the young fish to their natural habitat once they are large enough. The conditions needed to incubate and hatch the eggs, however, prove to be complex, and it is difficult to get it right in a controlled environment. This, along with the inability to keep many huchen in a confined area for very long, is making conservation efforts very difficult. Re-establishing the population of this fish is considered important to the ecosystem and population of Europe, and efforts to save the huchen will most likely not stop.

Frequently Asked Questions

What is a Huchen?

A Huchen, also known as the Danube Salmon, is a large freshwater fish native to rivers in Europe, particularly the Danube basin. It's a member of the salmon family and can grow up to 1.5 meters in length, weighing over 50 kilograms. Huchen are prized by anglers for their size and the challenge they present when fishing.

Where can Huchen be found?

Huchen are primarily found in clean, cold, and well-oxygenated rivers of the Danube River basin. Their range extends through countries like Germany, Austria, Czech Republic, Slovakia, and down to the Balkans. However, due to habitat loss and overfishing, their populations have declined, making them a species of concern in many areas.

What do Huchen eat?

Huchen are apex predators in their aquatic ecosystems, feeding on a diet that includes fish such as grayling, chub, and barbel. Juvenile Huchen may also consume insects and crustaceans. Their predatory nature reflects their importance in maintaining the balance of their river habitats.

How do Huchen reproduce?

Huchen spawn in the spring, typically from March to May, depending on the water temperature. They prefer gravel beds in clean, fast-flowing waters for laying eggs. Females can lay several thousand eggs, which hatch in about 30 to 35 days. The survival of young Huchen is crucial for the continuation of the species.

What are the conservation statuses of Huchen?

The Huchen is considered a threatened species, with its status varying by region. According to the International Union for Conservation of Nature (IUCN), the Huchen is listed as "Endangered." This is due to factors such as habitat destruction, pollution, and illegal fishing, which have all contributed to their decline.

Can Huchen be fished legally?

Legal fishing of Huchen is subject to local regulations, which often include strict catch-and-release policies, seasonal restrictions, and licensing requirements. These measures aim to protect the species while still allowing controlled angling activities. Anglers should always check the latest regulations before fishing for Huchen to ensure compliance with conservation efforts.
