This study investigated the annual changes in ovary development in hooksnout carp and methods to improve artificial breeding and promote its rapid commercialization. The annual range in the gonadosomatic index (GSI) in female hooksnout carp in Hubei Province was 1.16%–11.65%. The spawning period was from mid-April to mid-July, and the average absolute fecundity of the female before spawning was 6165.4 eggs. In autumn, when the water temperature gradually decreased (September to October), the GSI of the ovaries gradually decreased, and the ovaries degenerated to phase III and entered hibernation. In February of the following year, GSI of the carp was relatively low (1.16%–1.65%), and the proportion of phase III oocytes in the ovary increased after a further decrease in water temperature to ＜8.0 ℃ in February. In the scaled-up artificial breeding experiment, the combination of luteinizing releasing hormone (LRH-A2; 5 μg/kg) and human chorionic gonadotropin hCG (1000 IU/kg) had the best induction effect of 87.0%. A 0.3% NaCl solution was the best fertilization medium, with an optimal sperm-to-egg ratio of 5.0×104 –1.0×105 : 1, which produced average fertilization and hatching rates of 66.6% and 80.1%, respectively. The induction time was 20.0–26.0 h before May 15, 16.0–17.0 h after May 15, with accumulated temperature of 400.00–430.00 ℃·h. The hatching time was 69.0–90.0 h in water of 20.0– 25.0 ℃, and 42.5–48.0 h in water ＞26.0 ℃, with a hatching accumulated temperature of 1200.00–1300.00 ℃·h. This study also successfully conducted second-induced spawning of hooksnout carp broodstock in the same year and found that the spawning effect of the second breeding was not substantially different from that of the first. This study achieved scaled-up artificial breeding of hooksnout carp, laying an important foundation for the genetic improvement and commercialization of hooksnout carp.
