[Living space in zoos--criteria for species-specific animal husbandry]

Keeping wild animals in captivity is still object of criticism, above all due to the fact that room is restricted for these animals. But wild animal husbandry is basing on several factors: It has to concern physiological requirements as well as natural behaviour patterns, so as actions and reactions of wild living animals caused by ecological occasions have to be replaced by suitable arrangements. Most of the time proper animals husbandry is valued by quantity; in that way, that the measurements of artificial homes are often supposed to be more important than the quality of this enclosures. Optimal feeding, social structure, stimula for behaviour patterns like playing, breeding an rearing in calmness and well trained keepers are other basic requirements for wild animal husbandry. Criteria for keeping wild animals should not be scheduled by restrictive arrangements; innovations would be complicated by any regulations.
