1. How to raise river clams and produce pearls in a fish tank? Can anyone give a detailed answer?

The fish tank environment is not suitable for productive cultivation of pearl oysters. Because in such a closed fish tank, the small local environment cannot produce enough plankton for the oysters to filter feed. The cost of artificial addition is very high and it is not worth the cost, and it is easy to cause water corruption.

2. How to cultivate pearls with clams

When clams live in water, sand occasionally enters their shells and is difficult to expel. At this time, the clams will try to expel the sand and secrete a substance to help expel the sand. However, if the sand is not expelled, it will continue to secrete this substance. Over time, as the secretion of the sand increases, pearls are formed. The reason why they are round is that clams expel sand by peristalsis. In this process, the sand will naturally be evenly wrapped to form round pearls. This is a long process, so natural pearls are so precious. Cultured pearls are formed by artificially putting sand or other substances into shells.

3. How to cultivate clams to produce pearls

Conditions: gravel, river clams, adequate nutrition, and the skills to raise clams.

4. Pearls in the Mussels

Natural pearls are formed when the mud and sand in the river water enter the flesh of the river clams. The clams are stimulated and secrete a kind of mucus to wrap the sand. Over time, a pearl will be formed. This process is relatively long. Artificial pearl cultivation is to first cut a small hole in the clam meat, then insert a pre-prepared plastic sheet into the wound, and finally it seems that some medicine is used. The two types of pearls are easy to distinguish by color. This kind of professional question should be answered by a technician from the agricultural science station.
