Comparative Efficacy of Synthetic Hormones, Wova-FH and Ovatide on Breeding Performance of a Cypirinus carpio Var. communis in the Captive Conditions of Kashmir

Efficacy of Wova-FH and Ovatide on Cyprinus carpio Breeding

Abstract

This study assessed the efficacy of two GnRH-based synthetic hormones, Ovatide and Wova-FH, in the induced breeding of common carp (Cyprinus carpio) under the environmental conditions of Kashmir. A Completely Randomized Design (CRD) with three treatments for each hormone and a control group, performed in triplicates, was employed. The latency period varied significantly, with Ovatide showing superior performance. The shortest latency period (38±0.38 hours) was recorded at the highest dosage of Ovatide (0.7 mL/kg), compared to 44±0.57 hours for Wova-FH (0.5 mL/kg) and 55.5±0.5 hours for the control. Ovatide also achieved the highest ovulation rate (88.8%), significantly outperforming Wova-FH (55.5%) and the control (22.2%). Fertilization rates were significantly higher in Ovatide-treated groups, ranging from 85.25%±0.98 to 86.20%±1.12, compared to 83.42%±0.69 to 84.04%±1.15 in Wova-FH groups. However, hatching rates ranged from 67.80%±0.66 to 71.08%±1.37 across all treatments with no significant differences (p>0.05) between hormone-treated and the control groups, indicating that hatching success is independent of hormone type and dosage.

This study provides evidence supporting the use of Ovatide as a more effective inducing agent for carp breeding in Kashmir for sustainable aquaculture development in the region.
