Dr. Johnson's research focus has
been on the population genetics of groups which have
been impacted by stocking/harvesting programs and
other anthropogenic effects. Much of his research
has investigated the genetics of the blackbass (Micropterus)
and catfish (Ictalurus) by way of allozyme and
mitochondrial DNA analysis. Additionally, his
investigations of bivalves have shown how water
quality changes and shell harvesting can
dramatically affect genetic diversity and structure.
He has also been involved in several projects
studying stream dynamics of sportfish.
