  Avian Welfare Resource Center from the Avian Welfare Coalition - Captive Breeding of Exotic Birds by Monica ...
In reality, breeding birds in captivity is not going to save species in the wild because most captive breeding is done outside of official conservation plans and because captive breeding fails to address the leading causes of wild bird population decline — habitat loss, pollution, and the pet trade.
Another problem with using captive animals to replenish wild populations is that mental illness in captive animals is rampant due to deprivation of their natural environment, social structures and outlets for using naturally evolved skills.
Captive breeding for conservation purposes involves setting of target populations, definition of genetic and demographic objectives, allocation of habitat and coordination with field conservation projects.

 The Captive Breeding Program of the Mauritius Echo Parakeet
We think Txiki did this because of her background as a captive raised bird coupled with her individual reaction to the stress of our visiting to check the chick.
Twelve birds are scheduled for release, ten of these are from wild stock, two were captive bred in the aviaries.
Lack of food in the wild was by far and away the biggest problem this season with most pairs failing to breed and those that did attempt to nest found it very difficult or impossible to raise healthy chicks.

 Captive Breeding and Reintroduction of Canids
A commonly stated aim of many captive breeding programmes conducted in zoological parks is to produce founder populations for release into the wild in reintroduction programmes (Anderson 1986; Seal 1986).
Clearly, if captive breeding of endangered species followed by reintroduction into the wild is to be a viable conservation option, we must be able to breed endangered species in captivity.
A captive breeding programme aimed at improving captive breeding and increasing the potential stock for reintroduction is already underway.

 Hawksbill turtle ranching and captive breeding   (Site not responding. Last check: 2007-10-10)
There are two ways to "farm" sea turtles: (1) maintaining captive adults who breed in captivity and whose offspring are raised for use ("Captive Breeding", often termed "Farming") and (2) collecting turtles from wild populations (as eggs or hatchlings) which are then raised in captivity for use ("Ranching").
Captive breeding requires the maintenance of captive adult stock, entailing expense, and the manipulation of natural breeding behavior.
Sea turtle farms, whether for captive breeding or ranching, cannot be shown to be directly beneficial or proven to be fatally detrimental to the conservation of wild populations.

 Project Corroboree > Features > Captive breeding proposal
The result of the phone conference was to begin a program to increase the number of colonies of P. corroboree represented in captivity and therefore the genetic diversity of the captive colony in case the current trend of population decline continues.
Captive breeding will provide stock for experimental reintroductions that may enable us to identify a means of recovering the species in the wild.
It is therefore imperative that the captive breeding and release program is carried out, documented and monitored in such a way that we learn about what works and what does not work.

 Basilisks: Captive Care and Breeding
As with most captive reptiles or amphibians, full-spectrum lighting is necessary for the synthesis of vitamin D3 and utilization of calcium.
Successful breeding results from several factors: manipulation of humidity, temperature, and photoperiod, health of specimens to be bred, and careful incubation of eggs.
In captivity, basilisks are subject to a variety of diseases that are common to captive-raised reptiles.

 Asiatic Lion Information Centre - Captive Breeding Programme
For any captive breeding programme to be successful and of conservational value it is essential that the origins and genetic purity of the animals within that programme are known.
The development of captive breeding programmes became more structured throughout the 1970’s and became formalised to their current status with the introduction of the Species Survival Programme (SSP) by the American Zoo and Aquarium Association (AZA) in 1981.
A new programme was required to maintain a secure population in captivity and in 1990 the foundations of a European Breeding Programme (EEP) were laid with the receipt of four Asiatic lions (2 male, 2 female) of known purity by London Zoo from India.

 ACE Position Statement - The Captive Breeding Myth
In reality, breeding animals in captivity is not going to save species in the wild because a vast majority of captive breeding is done outside of official conservation plans.
Additionally, captive breeding fails to address the leading causes of the decline of populations of endangered species in the wild —habitat loss, pollution, and the pet trade in exotic animals.
The fact that the many breeders are interested in breeding and maintaining mutations (for example, the color of white tigers or the size of pot-bellied pigs) which generally fetch higher prices among exotic animal fanciers indicates that maintaining the natural integrity of the species is not paramount in their breeding endeavors.

 The Rôle of Captive Breeding and Reintroduction in Wild Dog Conservation
Second, captive breeding may serve to increase the world population of a species, providing a source of additional genetic variation that may be fed into wild populations.
Captive animals can also be used to perfect techniques for use on free-ranging animals, allowing protocols for immobilization and designs for equipment such as radio-collars to be tested in captivity before they are used in the field.
Captive animals can also be used to refine techniques already in use: for example, the belly scores used to estimate food intake (Appendix 2) could be calibrated using feeding experiments with captive dogs.

 Captive Breeding 2.3
And yet due to difficulties in captive breeding, some circus animals such as chimpanzees and elephants are in chronically short-supply - perhaps presaging their eventual disappearance from menageries.
Small wonder then that the notion of captive breeding for conservation in the even less sophisticated environment of the circus beast wagon resembles a theatre of the absurd.
Even so, apologists for captive breeding have some remarkable plans for the future of wildlife, as outlined by Colin Tudge, apparently without irony: "As human populations decrease from the 26th century onwards," he writes, "it will be possible for animals to live in the wild again.

 Captive Breeding Populations - National Zoo| FONZ
Captive breeding provides a means for conserving species that may not survive in the wild.
While captive populations are established for many reasons—such as conservation education, exhibit of interesting species, and research—establishing captive populations for saving species from extinction is an important contribution of zoos to conservation.
A goal of some captive breeding programs may also be to reintroduce animals back to the wild, as is the case with the global breeding program for the golden lion tamarin, the fl-footed ferret, and the Guam rail.

 Tortoise Trust Web - Captive breeding of the Egyptian tortoise
Captive breeding of the Egyptian tortoise Testudo kleinmanni.
The most remarkable feature of breeding behaviour in T. kleinmanni concerns vocalisation: both male and female kleinmanni are very vocal compared to most tortoises and the males in particular produce a sound not unlike a dove calling during mating.
In summary, the threatened status of this species in the wild emphasises the need to develop reliable captive breeding techniques which can be employed to maximise the productivity of stocks now in captivity and in future, hopefully, to reinforce depleted natural populations.

Amplexus is accompanied by a display of aquatic gymnastics, culminating in tandem loop-the-loops; during each loop, the female releases a single egg, which is embedded in the skin of her back by the male's movements at the crest of the loop.
Breeding condition is easily recognized in the female; the skin on her back thickens into a soft, dark-colored "pad", and her vent enlarges quite noticeably.

All captive gorillas, for example, or Siberian tigers or snow leopards were entered into the system as single populations, providing zoos with records so they could exchange animals in breeding loans.
Captive breeding will still play an important role in the new zoo, particularly in short-term rescues of species such as the golden lion tamarin and the Arabian oryx, and in the long-term care of others, such as cranes and ibises, that have no chance of survival in the wild, says New York's Conway.
