The Siberian Sturgeon is a large fish that comes from Russia and lives in the cold water of the north. The population has dropped dramatically in the last few years to reach a historic low level today. If people do not change the way aquaculture is done, this fish will have to pay the consequences. Fish hybridization, leads to a more efficient culture and that is one of the reasons that they are endangered. An organisation named IUCN (which is specialized in marine species protection) says that Siberian Sturgeons and more than 3,000 species living in fresh water are threatened. Farm can prevent extinction by keeping hybridized fish in close area so they do not reproduce with wild fish. This fish has been an endangered specie since 1996. The decline of the Siberian Sturgeon in the ocean will throw the ecosystem off balance and it will also affect other levels of the food chain.
