You can squeeze the black Mary fish when it is difficult to give birth. If they have just had a difficult birth, the breeder can use the change in the environment to stimulate their production. If environmental stimulation has no effect, then artificial midwifery is carried out. When helping the black Mary fish to produce, the breeder can gently press the fish body from the head to the tail, just squeeze out a few small fish blocked in the genital mouth, and they can continue to produce by themselves.
If the
black Mary fish cannot give birth for a long time, the breeder can help them squeeze manually, because they are ovoviviparous, it is easy to have dystocia, if they do not squeeze manually, they are likely to die of dystocia. As soon as they have dystocia, breeders do not need immediate artificial delivery, but can stimulate their production by changing water or increasing water flow. If environmental stimulation fails to help them produce, the breeder will adopt the method of artificial midwifery. When helping the Mary fish to produce, the breeder only needs to squeeze out a few small fish blocking the spawning mouth, and the rest still needs the Black Mary fish to produce itself. If the breeder squeezes them all out, the body of the black Mary fish will be damaged, and the small fish will not survive easily. Two, black Mary fish how to midwifery
1, environmental changes: breeders can stimulate their production by warming up, this method is more suitable for the emergence of dystocia.
2. Water flow stimulation: Breeders can also turn on the water pump and massage their abdomen with tiny water flow, which can also promote their production. But the water flow should be small and slow, otherwise they will have a stress response.
3. Caesarean section: If the Mary fish is dying of dystocia, the breeder needs to cut open their abdomen and take out the small fish. However, it is difficult for the female fish to survive after cutting, so try not to use it.
