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:
“There a captive sat in chains
Crooning ditties treasured well
From his Afric’s torrid plains.
Sole estate his sire bequeathed,—
Hapless sire to hapless son,—
Was the wailing song he breathed,
And his chain when life was done.”
—Ralph Waldo Emerson (1803–1882)
“Not everyone knows how to be silent or to leave in good time. It happens that even people of good breeding fail to notice that their presence provokes in the weary or preoccupied host a feeling akin to hatred, and that this feeling is tensely concealed and covered up with lies.”
—Anton Pavlovich Chekhov (1860–1904)
