Abstract


Induced spawning of fresh water Raikhor Bata, Cirrhinus Reba was carried out in captivity using Ova prim (sGnRH+ Domperidone). The optimum dose of Ovaprim (0.3 ml/kg of body weight for male and 0.5 ml/kg for female) were standardized based on three experiments, viz., fecundity (relative fecundity), and response time (hrs) and fertilization rate at different doses. Maximum fecundity (9120) obtained at 0.5 ml/kg of body weight. Hatching conducted in a specially designed inverted at 2 liter thumps up bottle following the mechanism of glass jar hatchery and the spawns are reared at nursery pond by placing the hatchlings in the hapa. This innovative and cost effective technology will certainly add a new era in the seed production of Cirrhinus Reba including some other indigenous fishes of fresh water sector.
