There are 13 domestic animals native to Slovenia, of eight species (hen, pig, dog, horse, sheep, goat, honey bee, and cattle). Among these are the Karst Shepherd, the Carniolan honeybee, and the Lipizzan horse. They have been preserved ex situ and in situ. The marble trout or marmorata (''Salmo marmoratus'') is an indigenous Slovenian fish. Extensive breeding programmes have been introduced to repopulate the marble trout into lakes and streams invaded by non-indigenous species of trout. Slovenia is also home to the wels catfish.
