Abstract: Common carp (Cyprinus carpio) is an important exotic major carp having high consumer preference for its nutritive values and organoleptic properties. Its faster growth rate and proper utilization of ecological niche makes it a suitable candidate species for aquaculture. A study was carried out to observe the effect of different inducing agents, viz. Ovatide, Wova –FH and Gonopro-FH on fertilization rate and hatching percentage of common carp, in eco-carp hatchery in a private fish farm at Sarakana village of Khordha district. The experiment was divided in three treatment groups i.e T₁ (Ovtide treated fish), T₂ (Wova-FH treated fish) and T₃ (Gonopro –FH treated fish). The fertilization was found 90% with Ovatide75.23% with Wova-FH and 88.54% withg Gonopro-FH. However hatching percentage was high (80%) in Gonopro-FH treatef fish, 69% with Ovatide treated fish and 45 % with Wova-FH. A comparison was carried out for fecundity, fertilization, and hatching rate during the induced spawning of Cyprinous carpio administered single dose of Ovatide, Wova-FH and Gonopro-FH. Gonopro-FH performed much better than Ovatide and Wova-FH. The results suggests that breeding and seed production of common carp with the inducing agent Gonopro-FH gives better result than other inducing agents in the form of massive scale seed production.
