Captive Breeding of Endangered Ompok pabda with Ovatide

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...

More Information
Summary: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.
