Captive Breeding 2

captive breeding what: Captive breeding is the process of breeding animals in human controlled environments with restricted settings, such as wildlife reserves, zoos and other conservation facilities; sometimes the process is construed to include release of individual organisms to the wild, when there is sufficient natural habitat to support new individuals or when the threat to the species in the wild is lessened. Aim: to reintroduce the captive-breed animals into the wild to restore the original population. Can be more successful in national park / other protected area. ow: that members of a wild species are captured, then bred and raised in a special facilit! under the care of wildlife biologists and other e"perts. #roblems: $. usual l! dif ficult t o imp lement for hi ghl! mobile sp ecies lik e some migrator! birds %e.g. cranes& and fishes %e.g. ilsa&.
