TRAVERSE CITY,
Mich. (AP) — A newly released study says Asian carp may be reproducing in
more places and for longer periods than previously thought.
That's a bad
sign for natural resource managers looking for ways to stop the invasive
fish from reaching more rivers and keep them out of the Great Lakes.
Several
varieties of Asian carp have infested the Mississippi River and many of
its tributaries. Scientists say they may be out-competing native species
for food.
A Purdue
University study released Tuesday says the aggressive fish are spawning in
waters that had been considered too narrow or with currents too slow for
their offspring to survive.
Scientist
Reuben Goforth says it's uncertain whether eggs laid in those outlying
areas will survive to adulthood. But he says findings illustrate the
carps' ability to adapt.
