Bisoniana LXXIX. Immobilizing and marking of the European bison

Immobilization and marking of the European bison Bison bonasus (Linnaeus, 1758) was carried out in the Białowieża Primeval Forest over the period from 1977-1980 in connection with ecological studies. At first the preparation Rompun (Bayer) was used in a 20% solution injected intra-muscularly in doses of 2-3 ml/kg, but later Immobilon (Reckitt & Colman) was administered, remote injected by a Telinject gun, either into animals enclosed in a corral or directly while amongst the herd.
