Fishery
Biologist
 Whether
he's filtering water samples in a laboratory to identify
the host fish needed to help prevent the extinction
of an endangered mussel species, sitting at a desk pondering
spatial trends in the concentration of polychlorinated
biphenyls found in Mississippi River mayflies and catfish,
swatting mosquitoes while downloading data loggers at
remote sites to track the migratory of movements of
paddlefish and lake sturgeon, or sweltering under the
hot summer sun to survey the distribution and abundance
of invasive fish in the congested Chicago Waterways,
Mark has enjoyed searching for answers to puzzling fishery
resource questions in the upper Midwest throughout his
career. Employed in the La Crosse area by the Department
of the Interior since 1986, he began his professional
career here with the U.S. Fish and Wildlife Service
as a research fishery biologist studying the biological
availability and effects of persistent chemical contaminants
on fish and aquatic invertebrates. In 1995, Mark brought
his research-trained background of inquisitiveness,
innovation, and attention to detail with him when he
moved across town to begin working as a member of the
Service's La Crosse Fishery Resources Office (FRO) on
fishery management and aquatic ecosystem issues in Wisconsin,
Minnesota, Iowa, and Illinois. He has recently played
a lead role on several La Crosse FRO projects involving
a wide variety of species that include lake sturgeon
and paddlefish in the Upper Mississippi River, winged
mapleleaf mussels in the St. Croix River, sport fish
at the Necedah National Wildlife Refuge, and invasive
fish (round goby and Asian carp) in the Chicago Waterways.
Mark's technical writing and editing skills are also
used to help prepare many of the project reports for
clients served by this office, as well as public news
releases and critical reviews of research proposals
and manuscripts for aquatic science colleagues and journal
editors.
