Spawning along Wolf River

It is Lake sturgeon spawning season in Wisconsin.
We drove where the action was; indeed, spawning
was in full force.  People drive for miles and school
buses full of students arrive to see this pre-historic
fish up to six feet long arrive to follow nature's
call to reproduction.  The females are larger than

by five males all waiting to fertilize the many eggs
of one female.  In the next few days, I will
post this process on Bliphoto.  I find the process
fascinating and hope you do also.
