CAPTURE METHODS IN FIVE SUBSPECIES OF FREE-RANGING BIGHORN SHEEP: AN EVALUATION OF DROP-NET, DRIVE-NET, CHEMICAL IMMOBILIZATION AND THE NET-GUN

摘要: Six hundred thirty-four bighorn sheep (Ovis canadensis) were captured in the western United States between 1980 and 1986, using four different methods: drop-net (n = 158), drive-net 249), chemical immobilization =90) net-gun =137). The was found to have considerable advantages over use of ground nets methods for capturing sheep. Evaluation specific outcome categories individual sheep, including normal, compromised (stress-induced), mortality from capture myopathy (CM), accidental mortality, revealed significant differences these rates groups (P < 0.05). resulted lowest proportion at 11% (15/137), had no CM a 2% (2/137) mortality. drop-nets 15% (24/158), rate (3/158), an 1% (2/158).
