Crews looking for Asian carp in Lake Calumet
Crews in Chicago are on the hunt for Asian carp this week. The term Asian carp refers to two species: bighead and silver carp. The crews are looking for the carp in Lake Calumet, which is linked by a river to Lake Michigan. Asian carp have been found in the rivers that feed into Lake Michigan from Illinois.
John Rogner is the assistant director of the Illinois Department of Natural Resources. He says they’re looking for live carp after finding carp DNA in Lake Calumet.
He says it could mean there are live Asian carp in the lake.
“But there are some other possibilities. One is that there is DNA that comes upstream from downriver from boat hulls; it might be coming from restaurants in parts of Chicago that come out through the storm sewers.”
Some restaurants in the city serve Asian carp, so waste water could contain DNA from the fish. Rogner says people could also be releasing live carp into the lake, even though that’s illegal.
He says so far this week, they have not found any live bighead or silver carp in Lake Calumet.
