Limitations of Captive Breeding

Biology 320 Dr. Nissen 08 November 2012 Limitations of Captive Breeding While the intake of captive breeding has grown enormously in the more new-fangled years there has been a complete insufficiency of attention pay to the limitations placed on that jeopardise species by the captive breeding programs. Limitations such as establishing self-sufficient captive populations, light success in reintroductions, laid-back costs, domestications, preemption of other recover techniques, disease outbreaks and maintaining administrative continuity stick out all been significant ( Snyder et al. 996). We will review the self-sufficient captive populations, reintroductions, and domestications, these ar among the most important limitation factors for the review. Establishing self-sufficient captive populations obtaining consistent rejoinder and survivorship under captive conditions has proven quite difficult with many species. there argon a variety of reasons as to why there has been non starter to breed well in captivity, and identifying these factors can be difficult and are still unknown even after many years of experimentation.Because of poor reproduction the self-sustaining captive populations may never be achieved for roughly of the imperil species (Snyder et al. 1996). In a recent review of 145 reintroduction programs of captive-bred animals, by and large vertebrates, only 11% of the cases were successfully reintroduced into the wild populations (Beck et al. 1994). The causes of the reintroduction failure of the captive bred animals start out from a failure to correct the factors originally causing significant behavioral deficiencies in the released animals, to social behavior.The behavioral issues are typically seen in the animals that lack the opportunity to associate with wild individuals in a natural shot during the critical learning periods. Many of the problems affecting captive preservation and reintroduction of endangered species are results of genetic and phenotypic changes that occur in captivity as well (Snyder et al. 996) and this directly affects the domestication of the captive-bred animal. The implications of the state-of-the-art genetic and phenotypic changes are more serious than recognized for the species in gigantic-term captive breeding. Because of progressive domestication the general expectation that one can preserve endangered species in captivity without significant change over a long period of time should be abandoned (Snyder et al. 1996).
