Mussels

This weekend I am at a conference at Treasure Island Casino.

This morning we took a bus to a mussel propagation lab in Lake City. Years ago people overharvested mussels to make buttons. 
 
An example of a mussel shell used for buttons.

Most mussels use specific fish to propagate. The eject their larva into the fish's face so the larva can attach to the gills. Here are some baby mussels in a tank. The mussels spend two years here in the lab before they are returned to the wild.

Mussels from this lab are put into the Mississippi River, the Saint Croix River, and the Cedar River near Austin, MN.
