7년령, 체중 98 kg의 수컷 점박이물범에서 아랫입술과 눈 주위에 홍반, 탈모, 비후 등을 특징으로 하는 피부염이 관찰되었다. 진단을 위해 병변부위 피부소파를 실시하고 Sabouraud dextrose 배지에서 3일간 배양을 하였다. 그 결과 크림색의 윤기 있는 둥근 집락들이 관찰되었으며 집락을 슬라이드글라스에 도말하여 그람염색처리 후 현미경검사를 실시한 바 전형적인 효모양의 세포들이 관찰되었다. 특징적인 피부염의 임상증상과 현미경검사로 칸디다증으로 진단하였으며 치료를 위하여 itraconazole 1 mg/kg을 2주간의 간격으로 1주일 동안 먹이와 함께 투약하는 것을 3회 반복하였으며 투약개시 후 6개월여 뒤에 완전히 회복되었다. 그동안 국내에서 점박이물범에서의 칸디다 피부염 증례보고는 없었다. 점박이물범이 천연기념물로 지정되었을 뿐 만 아니라 국제적으로도 멸종위기에 처한 야생동물인 만큼 본 증례보고가 사육 상태 또는 야생에서 칸디다 피부염의 진단과 치료에 도움이 될 것으로 생각된다.

Identification of individuals is a standard tool used to study animal behavior and ecology. Numerous studies based on photographic identifications of various marine mammal populations have been successfully conducted. The objective of this study was to validate a photo-identification method for spotted seals. We tested the method using 4,939 photographs gathered in 30 field surveys from 2006 to 2008 on Baekryongdo, Korea. In 2006, 20 individuals were identified and cataloged using unique spot patterns on their left chick pelages as a natural marker. In 2007 and 2008, three and nine individuals, respectively, were recaptured, with six individuals continually recaptured during the entire survey period. We confirmed that the spot patterns of spotted seal pelages were constant in shape and location throughout time. These characteristics offered an opportunity to consistently identify individuals within a population over the long survey period. The use of photo-identification has great potential for mark-recapture studies.

This study investigated the distribution of spotted seals, Phoca largha, inhabiting the coast of Baekryongdo. Monitoring of spotted seals in Baekryongdo was conducted between June 2006 and November 2008, using a 5-ton fishing vessel 1hour before low tide. The monthly maximum number of observed seals was 274 in September 2006, 139 in September 2007, and 213 in August 2008. Average observed monthly counts were largest in August and September. Relatively more spotted seals were observed when there were few cloudy days and plenty of sunshine. Bycatch, stranding, and observations of spotted seals have been reported along the coast of the Korean peninsula since 2000, and spotted seals were observed four times in the western coastal region, three times in the southeastern region, and 12 times on the east coast. This suggests that spotted seals inhabiting Baekryongdo migrate to the East Sea via the West and South seas as individuals or in groups.
