First, the choice of species of fish: To choose a mature, weighing more than 500 grams of fish. 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.
Second, male and female with: After selecting a good male and female fish, with a ratio of 1:5 to 7 to match. If you put more squid, you can speed up the estrus of female squid.
Third, hanging eggs spawning: the male and female fish in the fish hanging in the water, and place the fish nest, the fish back approximately 3 cm below the surface of the water, in order to use temperature stimulation and microfluidic stimulation to reach 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.
Fourth, incubation instructions: (1) spawning pool and hatching pool 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 18-22°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.
Fifth, artificial aphrodisiac: artificial anthropogenic to the squid, can make squid spawning on time, 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 ~ 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 the family fish oysters to keep micro-irrigation stimulation. Spawning takes place 10 to 15 hours after injection, and the ovulation rate is generally increased by about 40% compared to the natural ovulation rate.
