Ictiobus niger | Black Buffalo

Black Buffalos are a common sucker species that typically make spawning runs numbering in the 10,000s in the early spring into smaller streams and tributaries of larger river systems.  These runs are quite impressive and sometimes there are so many fish in the creek it looks as though you could just walk across the creek on the back of the fish. 

 

These particular Black Buffalo are from spring runs into Citico Creek in March-April.  CFI assisted in collecting eggs and milt in 2006 for a larval study for Nevan Aspinwall at SLU (St Louis University).  We reared so many of these a few of them stuck around at CFI for a little while.
