Abstract

The field study was carried out on 11 rookeries in the Gulf of California in Mexico. A total of 288 pups and two adult females of the Califonia sea lion (Zalophus californianus) were anesthetized with isoflurane in a portable anesthesia machine. Duration of the anesthesia in the pups was six to 25 min (mean 12.51; SD ± 4.38). An average of 24 pups were worked with in each island, (a range of 16-29 animals), from an estimated two to 42 days of age, and six to 17.4 kg each (mean 10.41 kg; SD ± 2.02) totaling 137 males and 151 females. Induction in the adult females took from four to 10 minutes and they were anesthetized for one hour and twenty minute, presenting prolonged apneas. The inhaled anesthesia with isoflurane proved to be an effective and safe method for the inmobilization of free ranging California sea lion pups and adult females, and allowed us to obtain quality data in a situation of limited work time, rocky beaches and hot weather during the summer.
