Abstract

Steller sea lions (Eumetopias jubatus) rarely strand in areas monitored by humans, and there is little published data on the diseases, parasites, nutritional state, and stress levels of Steller sea lions in the wild. In May 2002, a female Steller sea lion pup (EJS-02-01) was sighted separated from her mother after strong storms in Southeast Alaska. After 5 days of observations, EJS-02-01 was transferred to the Alaska SeaLife Center (ASLC) in Seward, Alaska. During 11 mo of rehabilitation at ASLC, body weight was monitored and opportunistic fecal samples (n = 86) were analyzed for corticosterone concentrations. Fecal corticosterone concentrations ranged from 15 to 3,805 ng/ g for EJS-02-01. Peak corticosterone values reflected responses to acute stressors during rehabilitation. EJS-02-01 was successfully released at Gran Point, Alaska, in April 2003. Fecal corticosterone assay monitoring provided a valuable tool to monitor various stressors and is useful in monitoring long-term situations like rehabilitation.

摘要

北海狗（Eumetopias jubatus）很少在人类监测的区域搁浅，关于野生北海狗的疾病、寄生虫、营养状况和应激水平的公开数据也很少。2002年5月，在阿拉斯加东南部遭遇强风暴后，一只北海狗幼崽（EJS - 02 - 01）被发现与母亲分离。经过5天的观察，EJS - 02 - 01被转移到阿拉斯加苏厄德的阿拉斯加海洋生物中心（ASLC）。在ASLC进行11个月的康复期间，监测了其体重，并对采集的86份粪便样本进行了皮质酮浓度分析。EJS - 02 - 01的粪便皮质酮浓度范围为15至3805纳克/克。皮质酮峰值反映了康复期间对急性应激源的反应。EJS - 02 - 01于2003年4月在阿拉斯加的格兰角成功放归。粪便皮质酮检测监测为监测各种应激源提供了一种有价值的工具，并且在监测康复等长期情况时很有用。
