How long will raw mussels last refrigerated?

Surely raw mussels are fresh mussels meaning they are still alive,

That being the case keep live mussels in a cool place in a pail/bucket of water and feed lightly with oatmeal cereal (not cooked) salt the water slightly...

Then cook when required...Only eat the ones that open after boiling that is the safe way to be sure..

Shellfish should not be stored in refrigerator in its raw state...Once cooked eat at once
