[0030] Incubation methods of sticky egg fry, including broodstock cultivation, spawning, insemination and hatching process:
[0031] 1. Broodstock cultivation
[0032] Broodstock selection is carried out before overwintering in autumn, and broodstock with good traits and development are placed in the early breeding pond. In the early second year, when the water temperature was above 9℃, the feed was started, and the main feed was corn residue and malt. The initial feeding amount accounts for 0.2% of the fish's body weight, and the feeding amount is increased as the water temperature increases. When the water temperature stabilizes above 17°C, start regular flushing and aeration. Stop feeding one week before the induction of labor, flush water every day, and gradually increase the flushing time from 1 hour to 3 hours. When the water temperature stabilizes above 18 ℃, you can start to select carp and crucian carp broodstock to induce spawning.
