The following six of Mustelids inhabit the wilds of South Korea, but I have never seen any of them in the wild.
- Amur yellow-throated marten
(Martes flavigula borealis)
- Amur badger (Meles leucurus amurensis)
- Eurasian otter (Lutra lutra)
- Siberian weasel (Mustela sibilica)
- Korean weasel (Mustela sibirica coreanus)
- Jeju weasel (Mustela sibilica quelpartis)
- Korean least weasel (Mustela nivalis mosanensis)
And next following is a Mustelids list that I could saw in Korean zoos.
Amur yellow-throated marten (
Martes flavigula borealis): A total of four are at the Korean zoo: three at Seoul Zoo and one at the National Institute of Ecology, and all of them were rescued from the wild. I know that these two facilities are paying attention to rescued yellow-throated martens, because they are Korea's protected species and are difficult to secure due to their ecological characteristics.
Seoul Zoo, the only zoo that raises several martens, plans to build a closed facility at the Native Species Breeding Center in the zoo to conduct breeding studies. As it is a species that has not been properly studied in Korea, I hope that they will focus more on research than on displaying them for visitors.
Amur badger (
Meles leucurus amurensis): Basically, they are also mainly rescued from the wild, but If there is a badgers that has moved from the badger farm to the zoo, they are likely not amur badgers.
In Korea, there are farms that raise badgers to collect badger oil, saying it is good for health. Based on statistics from 2021 Korea's Ministries for Food, Agriculture, Forest and Fishery, there were 1775 badgers in 27 farms. Badgers here are imported from China, not from the wilds of Korea, and are known to have hog badgers and hybrid badgers. It is possible that they escaped to the wild, but there have been no studies.
As Korea's terrible asiatic black bear breeding problem, which has been done for decades to get bear bile, began to be resolved in the 2020s with the activities of animal rights groups that built sanctuary and rescued bears and moved them to zoos and oversea's sanctuary, analysts say that sanctions on badger breeding are needed next. Badgers are also clear wild animals, not livestock, so I think sanctions are necessary.
Eurasian otter (
Lutra lutra): It is an animal that has been strangely preferred by local public zoos in Korea since a few years ago. I think that the zoo's preference is due to its appearance that people consider cute and that it is a natural monument in Korea, and I think there was a positive part in that zoo's preference was expressed through the provision of a better environment through the amelioration of facilities. However, I don't think it's good for many zoos to focus too much on one species.
It has been pointed out recently that in the wild, they have been steadily protected in the absence of predators, so the number has increased and that they cannot cope with some otters attacking fish farms because they are natural monuments. The Ministry of Environment of the Republic of Korea is considering lowering the otter from the I Class endangered species to II Class.
Asian small-clawed otter (
Aonyx cinereus): While eurasian otters gets preferred in public zoos for just a few years, small-clawed otters have long been a favorite in private zoos and aquariums. This may be because it was possible to ignore the inconvenience of obtaining permission from both the Cultural Heritage Administration and the Ministry of Environment when keeping eurasian otters.
When I watching small-clawed otter in any facilitates, I could often hear visitors saying,
"I want to raise them at home!" However, not only does Korean law prohibit individual breeding of mammals above Cites Appendix II, and I think that visitors must not to get greed for animals but get knowledge about animals by observing living animals in zoos and aquariums. So I hope I don't hear that.
Domestic ferret (
Mustela furo): I'll skip the details. I understand it's mostly raising in private indoor zoos, but it's sometimes been in public zoos as well. Maybe it was probably donated by a civilian.
Other than this, more than two
Tayra(
Eira barbara) were on display at Everland's Nocturnal Pavilion until a few years ago. But I haven't been to the Nocturnal Pavilion, and the facility disappeared in early 2020, so this Tayra's whereabouts are unknown.
And the National Institute of Ecology initially planned to raising
Korean least weasel(
Mustela nivalis mosanensis) but it didn't come true. I think it's because they judged their chances of death in captivity were very high.
Last the following is list of Mustelids that were completely disappeared in the Korean zoos.
Sea otter (
Enhydra lutris): 63 Sea World(now 63 Aqua Planet)
North American river otter (
Lontra canadensis) : Seoul Zoo, Daejeon Zoo(now Daejeon O-world)
American mink (
Neogale vison): Seoul Zoo, Dalseong Park Zoo
European mink (
Mustela lutreola): Seoul Zoo, Dongnae zoo, Yongin Farmland(now Everland)
Korean weasel (
Mustela sibirica coreanus): Changgyeongwon, Seoul Zoo, Dongnae Zoo, Sungjigok Zoo(now Samjung The Park)
Japanese marten (
Martes melampus): Changgyeongwon. Although there is a record, it is doubtful that it was actually a yellow-throated marten.
