Lie on your back when you slaughter. First, put hemostatic forceps next to the turtle's mouth, let it bite tightly, pull out its head and neck, and let the assistant Baoding. The operator quickly presses the tortoise shell with one hand to prevent it from turning up; The other hand used a probe to pierce the occipital foramen of the head from the ventral side of the neck, completely destroying the brain. Then use a probe to pierce through the chest, destroy the heart and kill the turtle.

Use a scalpel to cut a 3-40 cm incision between the chest, mouth, back and abdomen, and use scissors and hemostatic forceps to pull out the muscles, fat, cartilage and contents. Cut the cervical spine from the incision with scissors, and then slowly peel off the skin of the neck and head, leaving only the turtle skin and skull, and remove the rest.

Hemostatic forceps was used to clamp the cotton and clean the brains and residual liquid in the chest and abdominal cavity of soft-shelled turtle. Cut off the muscles of limbs and tail with scissors.

Marinate the skull and fish skin from the inside of the incision with mixed powder of bittern skin, fill the gap between the back, abdominal nail and skull with ointment, and carefully place wire brackets instead of cervical vertebrae to support it.

When placing the stent, the wire at the end of the stent should be inserted into the tail and fixed, and the middle end of the stent should be fixed with its back armor and abdomen armor. After the inversion of the skin returns to its original state, pull out the head with hemostatic forceps, fill the head and neck with putty, and insert the wire at the front end of the bracket into the pillow hole of the head for fixation.

After the turtle specimen is made, the appropriate artificial eye is embedded in the eye socket, then it is properly shaped, painted with varnish, labeled and allowed to dry naturally, so that the turtle specimen can be displayed and preserved.
