First alpine sturgeon and caviar production
Tropenhaus Frutigen is considered a pioneer in the field of fish breeding in land-based aquacultures. A high-performance, professional production facilities for breeding freshwater fish is at the heart of the facility. 18-degree hot, high quality water from the inside of the Lötschberg mountain forms the ideal environment for the Siberian sturgeon. Fish stocks in Tropenhaus have now grown to around 80,000 sturgeons. Aside from the Siberian sturgeon, our aquarium boasts numerous other species, among them rare sturgeons such as the light albino sterlet, the spoon billet and the beluga.
