“…Ovaprim hormone is widely used in Family Cyprinidae for successful spawning (Muchlisin et al, 2014). Spawning is a natural process in which eggs or milt are expelled from the body of brooders in to surrounding of the water (Amezawa et al, 2018;Superio et al, 2021;Kucharczyk et al, 2022). Hatching is physiological change in which secretion of different hatching enzyme resulted in the breakdown of eggs shell and emerging of larvae (Yanagitsuru et al, 2021).…”

A breeding experiment was conducted on Hypophthalmichthys nobilis and Cyprinus carpio April to August 2022 at Tawakkal Fish Hatchery at Muzaffargarh, Punjab, Pakistan. A single dose of intramuscular injection of Ovaprim with 0.7 ml/kg for female and 0.2 ml/kg for male brooders of both species were administrated. After hormonal adminteration brooders were kept in the circular tank for spawning. The 100% ovulation rate was observed in both species. Spawning response was observed after the latency period of (8.80±0.1-10.84±0.02 hours) and (8.1±0.26-9.8±0.01 hours) in Hypophthalmichthys nobilis and Cyprinus carpio respectively at water temperature range from 22-28 °C. Fertilization rate (61-73%) was observed in Hypophthalmichthys nobilis while, in Cyprinus carpio it was (60-76%) at water temperature range 22-28 °C respectively. Degree-hours to spawning were calculated in Hypophthalmichthys nobilis (238.2±1.46-246.4±1) while in Cyprinus carpio it was (215.6±1.3- 226.8±1.28) respectively. Hatching rate of Hypophthalmichthys nobilis was calculated as (52-70 %), while in Cyprinus carpio it was (56 -71 %) and degree-hours to hatching was calculated as (748-784) and (682-702) respectively at water temperature range 22-28 °C respectively. Overall, the rates of fertilization and hatching increases with the increase of water temperature up to limit. These findings can be used to calculate spawning probabilities to enable future spawning predictions for the Hypophthalmichthys nobilis and Cyprinus carpio.
