Perdagangan Luar Negeri Kakatua Koki (Cacatua galerita Latham, 1790) Dan Usaha Penangkarannya Di Fasilitas Penangkaran Pusat Penelitian Biologi-LIPI

Abstract

Psittacine, for instance, sulphur-crested cockatoo (C. galerita) was widely traded, domestically and internationally due to its beautiful plumages and well-known smartness. It is essential to know the trading rate of the bird. The information can use both to control the trade and prevent over-harvesting from the wild. Captive breeding is one of few attempts performed to reduce wildlife over-harvesting. This research aimed to study the international trading rate of C. galerita and to review captive breeding management in our facility. The export data during 1981-2018 collected from CITES websites' database. Based on the obtained data, export activities were as follow: 7884 birds exported as reported by the importer. Meanwhile, 12.798 birds were reported by the exporter, and the birds exported to 39 countries. The birds exported using code C (bred in captivity), W (wild), F (born in captivity), U (unknown) dan I (confiscated or seized). Captive breeding performed as ex-situ conservation attempts to reduce wild harvesting. Captive Breeding attempts in Research Center for Biology LIPI successfully bred this species using three pairs of broodstocks. The obtained captive breeding data were as follow reproductive frequency 1-2 times/year with 1-2 eggs/clutch. The incubation period ± 28 days. Egg weight is 19 ± 1.12 g. Egg length 4.28 ± 0.08 mm and egg width 3.35 ± 0.05 mm. Weight of chicks seven days of age is 95 ± 2.34 grams. The chick comes out of the nest at ± 11 weeks and fledgeling age at ± 13 weeks. Feed consist of grains, fruits, vegetables, pellets, coconuts and bird cakes. Our captive breeding indeed was far from perfect. Implementation of recent technology still needs to be done to enhance our captive breeding management.
