As of today there are only two documented captive breeding of Varanus melinus.
First F2 Breeding of the Quince Monitor Lizard
Varanus melinus Böhme & Ziegler, 1997 at the Cologne Zoo Aquarium.
Abstract. We report the first breeding of the quince monitor lizard Varanus melinus in a European Zoo, which at the same time represents to our knowledge the first F2 breeding of the species in general. In June 2009, a clutch containing nine eggs was produced at the Aquarium of the Cologne Zoo by a V. melinus pair received seven years earlier as offspring from a private breeder.
Reproduction of varanid lizards (Reptilia: Squamata: Varanidae) at the Bronx Zoo.
Zoo Biol. 2012 May-Jun;31(3):374-89. doi: 10.1002/zoo.20389. Epub 2011 May 2.
Abstract.Captivity provides many opportunities for studying the reproductive biology of varanid lizards (Family: Varanidae; genus: Varanus). This article presents reproductive data for 12 varanid species maintained in captivity at the Bronx Zoo between 1977 and 2010. Five species, V. prasinus, V. beccarii, V. melinus, V. mertensi, and V. ornatus have successfully reproduced at the zoo, for which clutch, incubation, and hatchling data are presented, and compared with previously published values.
Video dated Sep 18, 2012 from Cincinnati Zoo showing hatching of V. melinus. No records have been provided as wether these eggs were produced by captive V. melinus or sourced somewhere else.
Importers and distributors will often claim their animals are captive bred and hatched.
Those claims have to be thoroughly scrutinized and absolute proof demanded. They may also claim farm hatching
as captive breeding, when in fact farm hatching is either collection of eggs or collection of gravid females in
the wild and has nothing to do with true captive breeding.
Captive breeding of V. melinus is very serious achievement and always is thoroughly documented.
