In the natural environment, mussels generally live in muddy, sandy or gravel such as rivers, lakes, ponds and streams. In winter and spring, when the weather is cold, we dig mud graves with axe feet and bury clams in the mud. The front abdomen edge is downward and the back edge is upward. Only the rear edge of the shell is exposed to external breathing and eating. Most of them are exposed to mud in hot weather. Individualized mussels generally live in turbid bottom water, still water with ph value of 5-9 or slow-flowing and relatively fertile water.
The food of mussels is mainly unicellular algae, protozoa and organic debris, such as rotifers, flagellates, green algae, reticulate algae, navicular algae, dinoflagellate algae, tetragonal algae, spindle-shaped diatoms, coryneform algae, crustacean debris and plant leaves.
