CATDOLL : CATDOLL: How to tell if a river clam is dead?

1. How to tell if a river clam is dead?

River clams need to breathe in water. If you drop a drop of ink into the water where the clams are kept, and you see the ink flowing quickly on the edge of the clam shell (indicating that water is flowing), it means that the clams are alive.

2. How deep do river clams live underwater?

Don't worry about how deep it is. Just go to a small unpolluted ditch and fish at the bottom of the river, or dig up the silt and you will find it.

3. Is there any instrument that can detect whether there are fish in the water?

Sonar detector! Use it at sea! Forget about it in the river! What a waste

4. Underwater Metal Detection

There is no better way. There is a tomb-robbing detector that can detect 7 to 8 meters deep with clear images. It is a bit difficult to do it with manpower alone. Otherwise, you can find an expert in Bagua and use Bagua to lock the approximate location. Then find a Luoyang shovel and slowly explore.
