Osteobrama belangeri (Valenciennes), locally known as Pengba, is a highly esteemed and endangered indigenous minor carp of Manipur state in northeast India. A trial on induced spawning and hatching of this species was conducted using Ovatide, an ovulating agent. Complete spawning was observed within 8 hours and larvae hatched in 26 hours at 28-29°C. Results showed 95.0 ± 1.05% fertilization and 88.8 ± 1.04% hatching rate. The paper discusses the efficacy of the ovulating agent, Ovatide, and the potential for large scale seed production of O. belangeri to promote commercial culture as well as for conservation of this species.
