Induced breeding of common carp (Cyprinus carpio) by using synthetic hormones

Abstract

This research paper presents a five-month study (July 2022 to November 2022) on induced breeding in common carp ( C. carpio ) using synthetic hormones Gonopro-FH and Ovaprim. The goal was to assess their effects on fertilization and hatching rates through the stripping method. Brood fish were administered Gonopro-FH and Ovaprim to stimulate ovulation, and the impact on fertilization and hatching rates was closely monitored. Ovaprim outperformed Gonopro-FH, showing higher fertilization (82%) and hatching rates (76%). The study also explored embryological development, revealing that Ovaprim resulted in fewer malformations in eggs, potentially leading to healthier offspring. Overall, Ovaprim proved more effective for inducing breeding in common carp through the stripping method, offering higher hatching and fertilization rates compared to Gonopro-FH. These findings are vital for the aquaculture industry, providing valuable insights into sustainable and efficient common carp reproduction using hormone-induced breeding techniques
