2. How to breed carp

Using flowing water fish ponds to breed carp fry can shorten the fry breeding cycle and increase production. 1. Selection of breeding fish Select breeding fish with mature glands and a weight of more than 500 grams. The abdomen of the female fish is required to be swollen and soft, and the area around the anus and genital opening is red, swollen and congested; when the male fish squeezes its abdomen, white semen flows out, and there is no redness or swelling near the anus. 2. Male-female matching After selecting male and female breeding fish, match them at a ratio of 1:5-7. Put more male carp to accelerate the estrus of female carp. 3. Hanging water for spawning Place male and female breeding fish in a fish basket and hang them in the water, and place a fish nest. The fish back is about 3 cm below the water surface. Use temperature difference and micro-flow water to stimulate it to lay eggs. 4. Hatching instructions ① The water in the spawning pool and hatching pool should not be too fertile. If the water is too fertile, it will easily cause the breeding fish to float, and not lay eggs or hatch eggs due to lack of oxygen in the water body and no fry can be hatched. The spawning pool and hatching pool should be continuously injected with new water to maintain micro-flow water. The water temperature should be 18℃-20℃. ② For ovaries, it is better to use pseudo-daffodils with roots that are refreshing and without mixed pulp. Cut off the stems and leaves to prevent the eggs from being stuck and killed by the sun. 5. Artificial aphrodisiac Artificial aphrodisiac for carp can make carp lay eggs on time and increase the amount of ovulation. The method is: inject 50% glucose solution into mature female fish during the breeding season of carp. The injection site is the scaleless part at the base of the pectoral fin. The needle is inserted at a 45-degree angle. The injection volume is determined by the weight of the female fish. Each fish is injected with 3-5 ml. After the injection, the female fish is placed in the spawning pond, and then each female fish is paired with two male fish.
