Between 1998 and 2008, 621 Steller sea lions ( Eumetopias jubatus , SSL ) were captured underwater by SCUBA divers and anesthetized with isoflurane ( n = 602) or sevoflurane ( n = 19). We found significantly faster induction time (X ± SD ) for sevoflurane (11 ± 6 min) compared to isoflurane (14 ± 6 min), as well as an interaction between anesthetists using the isoflurane protocol. Severe hypothermia with temperatures <35°C were measured in 22% of all animals, and had significant associations with month, length of anesthesia, and sex. Mortality rate was low (0.33%). We conclude that both isoflurane and sevoflurane anesthesia were effective for field anesthesia to safely handle and sample SSL .
