From the dinosaur age

Looking at the sturgeon, you may be able to sense that it belongs to an ancient and unique fish species. The sturgeon lived during the dinosaur age 200 million years ago and it hasn't changed a bit since then.

Feels its way to its prey

The mouth is located on the underside of its narrow, sharp head. In front of the mouth are 4 barbels. The sturgeon uses its barbels and highly developed sense of smell to track down its prey.

Isinglass (gelatine) from sturgeon

Isinglass (gelatine) used to be made from the innermost membrane of the sturgeons swim bladder. The word isinglass is from the Dutch: huizenblaas - huizen, a kind of sterlet; blaas, a bladder.

Sturgeon in Denmark

The sturgeon is not native to Denmark, but you can encounter it in Danish lakes and along the coasts. These are probably fish that have escaped from fish farms and put-and-take lakes.
