The Northeast-Midwest Institute Mississippi River Basin Program and the Mississippi Interstate Cooperative Resource Association (MICRA) hosted a Congressional briefing on
the ongoing efforts to control the spread of
Asian carp in the Mississippi River and Ohio
River Basins on Wednesday, July 25th.
Greg Conover of the US Fish and Wildlife
Service's MICRA discussed the nationwide approach of the control and management of Asian carp as well as its increased funding since 2015. He also touched on how this has enabled more state partnerships and more prevention and control efforts.
Nick Frohnauer of the Minnesota Department of Resources provided an
overview of the detection, assessment, and management of the species in the Upper Mississippi River Basin. These efforts include the creation of a management zone to prevent the upstream movement of Asian carp with
strategic deterrents that include acoustic barriers and flow modifications,
while also reducing the population of the fish in the zone through mass
removal by means of commercial fishing and targeted netting.
Ron Brooks of the Kentucky Department of Fish and Wildlife then explained
that those working on Asian carp management in the Ohio River Basin have
made similar efforts in order to reduce the number of fish in the middle region
of the basin, which currently is categorized as having observed spawning
patches. He also explained that one of the main upcoming efforts to address
the issue is to fund contract fishing between that region and the western
part of the river that is categorized as having established, verified spawning.
Aaron Woldt of the US Fish and Wildlife Service (USFWS) focused on the
success of acoustic deterrents and rays in laboratory and pond settings. He explained that the question now is whether bio-acoustic fish fences will work
on a large-scale system. USFWS has identified two large-scale field testing
sites to address this concern.
Finally, Bill Taylor of Fishing League Worldwide discussed the negative
impacts Asian carp have on recreational fishing and local economies including
less tourism and fewer tournament participants. He noted that
his
organization has been engaging with the public on this topic.
Overall, the briefing provided Congressional staff, regional and environmental organizations, and interested members of the public the opportunity to hear directly from stakeholders from the Upper Mississippi and Ohio Rivers about
the current efforts to monitor, control, remove, and deter the spread of Asian carp. It also facilitated a discussion of the impact that this invasive species has
on the recreational fishing and related industries.
