1. Fish selection: To select a mature fish that weighs more than 500 grams. The female squid has to be enlarged and soft in the abdomen, redness and congestion around the anus and genital hole; the male squid squeezes out of his abdomen with white semen outflow, and there is no swelling near the anus.
2. Male and female collocation: After selecting the male and female fish, match them in a ratio of 1:5-7. If you put more squid, you can speed up the estrus of female squid.
3. Drowning spawning: The male and female fish are placed in a fish larvae to suspend water, and a fish nest is placed. The back of the fish is approximately 3 cm below the water surface, so as to utilize the temperature difference stimulation and micro stream water stimulation to achieve its spawning. If 2 ml of 50% glucose is injected at the base of each pectoral fin of the female, the effect of spawning is better.
4. Incubation instructions: (1) The spawning pond and hatching pond water should not be too fat. If the water is more fat, it will cause the floating head of the fish, and it will not be hatched without spawning or spawning. Spawning ponds and hatching ponds should be filled with fresh water to keep microfluidic water well. The water temperature is preferably 18°C-22°C. (2) For producing ovaries, it is better to use a pristine daffodil that does not contain mud, and cut stems and leaves to avoid sticking the eggs to the sun. (3) Prevent males from eating eggs and increase hatching rate.
5. Artificial aphrodisiac: An artificial aphrodisiac for the squid can enable the squid to spawn on time to increase ovulation. The specific method is: In the breeding season of salmon, mature females are injected with 50% glucose solution. The injection site is at the base of the pectoral fin without fins. The needle is inserted from the 45° angle, and the injection volume is determined by the weight of the female. Each tail is injected with 3 Ml -5 ml. After the injection, the females were placed in the spawning pool and then each female was paired with 2 males. The spawning pool can be used to carry out family fish rearing, keeping micro-water stimulation, and spawning begins 10 hours to 15 hours after injection, and the ovulation volume is generally increased by about 40% compared to the natural ovulation rate. The eggs of the catfish are sticky eggs, which require production of ovaries, production of ovaries with narcissus roots or water grass, eggs attached to the fish nests, and hatching of the nests with eggs into the small fish larvae that have been cleared. It has been proved by practice that the benefits of using glucose as an artificial aphrodisiac to propagate salmon fry are: (1) simple, low-cost and suitable for widespread promotion in rural areas; (2) centralized spawning of species of fish for ease of management; (3) uniform size of fry, The fish is strong and has a high survival rate after stocking.
