Captive Breeding of Endangered Ompok pabda with Ovatide

摘要

The Pabdah catfish, Ompok pabda, was successfully spawned with the synthetic hormone Ovatide at two different doses (0.4 and 0.6 ml/kg of body weight of female). The latency period was 9-10 h at 0.6 ml compared to 10-12 h at 0.4 ml kg−1 of body weight. All the females spawned successfully. Average rate of fertilization (75.5 %) and hatching (60.5%) was higher with a dose of 0.6 ml kg−1, while lower fertilization (65.1%) and hatching rate (45%) were observed at 0.3 ml kg−1 of body weight. Fecundity ranged from 80-130 eggs gm−1 body weight of female. Eggs hatched between 12-14 h after spawning at a water temperature 28°-32°C. The mean egg diameter was 0.95 ± 0.15 mm.View full textDownload full textKeywordsLive gene bank, captive breeding, Ompok pabda, Ovatide, spawning, Northeastern IndiaRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10454438.2012.652027
