If you want to see animals, you should go see them in the wild. Perhaps one of the strongest conservation-based arguments supporting housing animals in zoos and aquariums today is that these facilities provide the ability to create “captive assurance populations” through ex situ breeding, with the goal of reintroducing some individuals back into the wild to restore or expand lost or declining populations (Beck et al. Conrad, Cheyenne C. Conrad et al. Assortative mating among animals of captive and wild origin following experimental conservation releases, Dam greenhouse gas emissions really add up, Foreign investors’ land deals in Africa could heighten water conflict. Animals sometimes escape their enclosures, endangering themselves as well as people. Lesson Plan: Not Just Birds and Bees. However, instead of simply placing endangered animals in captivity, we should spend our effort trying to prevent further species from becoming endangered.

The vast majority of captive breeding programs do not release animals back into the wild. Encyclopedia of False Arguments Against Keeping Marine Mammals under Human Care 16 Encyclopedia of False Arguments Against Keeping Marine Mammals under Human Care 17 Space in zoos and aquariums is very limited and inadequate for the animals Animals have a number of needs regarding the environment in order to survive. What is a Habitat Conservation Plan (HCP)? Breeding is carefully managed to control numbers and to prevent inbreeding. Their results were reported in the journal Biology Letters. In which situations are artificial habitats beneficial? Hosey, Geoff, et al. In which situations might they be harmful? (That’s possible if the “compatible genes hypothesis” is true.) One of the first successful programs was the reintroduction of the Arabian oryx. Captive breeding programmes are one of these ex situ conservation techniques (i.e., those performed outside of the range of the species in question) advocated by the IUCN, and may perhaps be the most important techniques when it comes to efforts to prevent the total extinction of some endangered species. Captive breeding -- where endangered animals are bred with the aim of releasing their offspring in the wild -- is a last-ditch effort to bring wildlife back from the brink. But PETA and many other animal advocacy organizations and big-cat rescue groups are determined to stop them. Just because reintroductions are successful doesn’t mean that the genes of reintroduced individuals mix in to the wider population of at-risk animals. a. Captive breeding programs are designed to increase the number of individuals in a population. By the end of the twentieth week of their reintroduction, there were a total of 59 litters of 189 baby mice, from 40 pairings. Table 1. Removing individual specimens from the wild further endangers the wild population because the remaining individuals will be less genetically diverse and may have greater difficulty finding mates. Captive Breeding may result in inbreeding, which results in a higher mortality rate. 2. How can captive-breeding programs and species-survival plans contribute to biodiversity and the health of ecosystems? While the child survived and was not badly injured, the gorilla was killed outright. Both accredited and unaccredited animal exhibitors are regulated by the federal Animal Welfare Act, which establishes standards for animal care. 3. For twenty weeks, the researchers observed the mice going about their business, keeping watch for any pairs successfully giving birth to baby mice.
