| Abstract: The goal of the study was to identify the artificial breeding period for Amblypharyngodon mola by monitoring fecundity and the gonadosomatic index. The highest fecundity and GSI values were found in June and October. The study examined how the hormones PG and synthetic SGnRHa affected the reproduction of male and female brood fish during the months of April, May, June, July, and October. The effects of the hormones PG and SGnRHa on the ovulation, fertility, and hatching rate of A. mola were assessed under closely observed conditions. Males receiving a single dosage of PG and SGnRHa had better spermiation results. The highest fecundity and GSI value were recorded in fish weighing 5.96±0.07 g, while the lowest fecundity and GSI value were found in fish weighing 0.42±0.04 g. The highest fertilization (97.04±3.12%) and hatching (86.02±2.10%) were found by the PG treatment, while SGnRHa resulted in the highest rates of both (98.04±3.12%) and hatching (87.12±2.40%). The finding was that PG and SGnRHa both work as well to induce ovulation, fertilization, and hatching in A. mola. The purpose of the study was to determine the ease of artificial breeding under controlled hatchery conditions utilizing both PG extract and synthetic SGnRHa inducing chemicals. |
