A dose of mg kg M99 supplemented by mg kg Rompun was found to be very effective. This dose is much higher than currently recommended . by Handbook of Wildlife Chemical Immobilization. Findings Muskoxen Ovibos moschatus are widespread throughout the Arctic and although there are reports of extensive use of etorphine and xylazine for the immobilization of muskoxen both in the field 1 2 and in captivity 3 systematic studies of the effects of these commonly used chemicals on these animals are few and far between. This note is based on 81 cases out of a total of 133 successful immobilizations of altogether 34 different muskoxen of both sexes and all ages in which age and also body mass of the animal was known by weighing subsequent to the immobilization. We arrived at doses that are much higher than those hitherto recommended 4 and we believe that our results will benefit muskoxen managers and researchers at large. The animals belonged to the University of Tromso and were roaming free on Rya island 69 40 N 18 58 E outside Tromso Norway and were behaviourally wild 5 . A variable number of animals usually 5-10 were driven into a 2 da. enclosure prior to immobilization where after the animals were approached on foot one at a time and subsequently a mixture of etorphine M99 mg ml Vericore Ltd.
