Precaution
1 Scrub the mud and the algae outside the shells at a proper time so that the female insects cannot attach and build tubes.
2 For pearl oysters that have been supplemented with female larvae, they can be treated with saline: saturated brine (335 g per litre) or 2/3 saturation (224 g per litre) or 1/2 saturation (167 per litre) Grams of salt), bath pearl shell 5 to 20 minutes. The operation procedure is to wash the pearl belay first in seawater and soak for about 5 minutes. When it does not come out of air bubbles, then put it in fresh water and soak it in bath for 10-15 minutes, and then bathe in salt water for 5-20 minutes. Remove the shade for about 15 minutes and return it to the sea. This method has a good therapeutic effect, but special care should be taken not to release salt water when the pearl shell is open, otherwise salt water will immerse in the shell and kill the pearl shell. Put pearl shells into sea water and talk about water treatment, that is, pearl shell release gas from the shell, double-shell tightly closed to prevent salt water from immersing, pearl shells that have just been treated are not treated with salt water.
