Captive Breeding
Captive breeding is the process of breeding rare or endangered species in human controlled environments with restricted settings, such as wildlife preserves, zoos and other conservation facilities. Captive breeding is meant to save species from going extinct. It is supposed to stabilize the population of the species so it is no longer at risk for disappearing.
This technique has been used with success for many species for some time, with probably the oldest known such instances of captive mating being attributed to menageries of European and Asian rulers, a case in point being the Pere David's Deer. However, captive breeding techniques are usually difficult to implement for highly mobile species like some migratory birds (e.g. cranes) and fishes (e.g. Hilsa). Additionally, if the captive breeding population is too small, inbreeding may occur due to a reduced gene pool; this may lead to the population lacking immunity to diseases.

Famous quotes containing the words captive and/or breeding:
“My Vanquisher, spoild of his vanted spoile;
Death his deaths wound shall then receive, & stoop
*nglorious, of his mortall sting disarm’d.
I through the ample Air in Triumph high
Shall lead Hell Captive maugre Hell, and show
The powers of darkness bound. Thou at the sight
Pleas’d, out of Heaven shalt look down and smile,”
—John Milton (1608–1674)
“Good breeding and good nature do incline us rather to help and raise people up to ourselves, than to mortify and depress them, and, in truth, our own private interest concurs in it, as it is making ourselves so many friends, instead of so many enemies.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
