 There’s Sturgeon Bladder in My Beer? Really?

Dear Guardian,  

Champagne wishes and caviar dreams may have been just a catch phrase of the television show “The Lifestyles of the Rich and Famous,” but caviar consumption has its costs and is devastating wild sturgeon populations.

Even if you’re not a caviar consumer, your beer or wine could contain isinglass, also know as a very pure form of gelatine from sturgeon fish bladders. Get on the bus for sturgeon and take our pledge to not consume any products from these imperiled fish.

Last month WildEarth Guardians and Friends of Animals requested that the CEO of, Jeff Bezos, ban the sale of caviar and other products derived from fifteen imperiled sturgeon species in his company’s online marketplace. The reason? Caviar harvesting is devastating sturgeon populations from Europe to Japan.

We have called upon chefs, restaurateurs, retailers, airlines, and the public to avoid products made from these endangered species, and now we’re calling on you to sign our pledge to avoid sturgeon products too.

Sturgeon are described by the International Union for Conservation of Nature as the most threatened group of animals on the IUCN Red List of Threatened Species. Many sturgeon are threatened by caviar consumption, and North America’s demand for caviar is driving both legal and illegal trade, as consumer’ demand far exceeds the supply. 

Do your part to help an imperiled species. Join us with your pledge to avoid products derived from endangered sturgeon.

For the Endangered Species,
