Marbled polecat of at least 30% in the previous 10 years. In 1996, it had been considered a species of least concern. The decline in marbled polecat populations thought to be due to habitat destruction (cultivation) and reduction in available prey by use of rodenticides. In Pakistan, it is listed as an endangered species. The marbled polecat was once sought for its fur, generally known as "fitch" or more specifically, "perwitsky" in the fur trade.<ref name="http://www.merriam-webster.com/dictionary/perwitsky"></ref> In 1945, Kabul shopkeepers were reported to have kept marbled polecats to exterminate rodents. Their journals also show some developed an adverse reaction to the strong
Polecat–mink hybrid zoologist Dmitry Ternovsky of Novosibirsk. Originally bred for their fur (which was more valuable than that of either parent species), the breeding of these hybrids declined as European mink populations decreased. Studies on the behavioural ecology of free ranging polecat–mink hybrids in the upper reaches of the Lovat River indicate that hybrids will stray from aquatic habitats more readily than pure minks, and will tolerate both parent species entering their territories, though the hybrid's larger size (especially the males') may deter intrusion. During the summer period, the diet of wild polecat–mink hybrids is more similar to that of the mink
