Concern Rises Over Grass Carp In Great Lakes
TRAVERSE CITY, Mich. (AP) — Fresh concern about the potential for grass carp to invade and seriously damage the Great Lakes.
A scientific paper just published by researchers at the University of Notre Dame shows evidence the invasive species could survive in all five Great Lakes.
The fight against Asian carp has focused mostly on bighead and silver carp, which could destroy food chains because they ear so much plankton.
Grass carp also come from Asia, and are used in many states to control aquatic weeds.
But according to this paper, the fish would eat plants needed for fish habitats in the Great Lakes.
