By loprespub on August 24, Lawrence River system seem to indicate that the fight against this invasive aquatic species is on the verge of failure. Major flooding in this part of the U. Four species of Asian carp have been introduced to North America: the bighead carp, silver carp, grass carp and black carp.
Project to block Asian carp from entering Lake Michigan moves forward
A new study says sport fish have declined significantly in portions of the Upper Mississippi River infested with Asian carp. Analysis of nearly 20 years of population data suggests the carp are out-competing fish prized by anglers, such as yellow perch, bluegill, and black and white crappie, the report said. Scientists have long suspected Asian carp of starving out other fish in the Mississippi and many of its tributaries. The peer-reviewed study this month in the journal Biological Invasions is among the first to establish a solid link, lead author John Chick said in an interview Friday. The trends that have been established here are not the trends we want to see in other places.
Study links Asian carp with Mississippi River fish drop
February 3, It's not good news for some of the most foreboding fish in Illinois swimming their way toward Lake Michigan. The next phase of the U. Army Corps of Engineers' project for the Brandon Road Lock and Dam near Joliet is moving ahead after state and federal funding has been secured.
A study led by University of Michigan researchers found that despite a drop-off in plankton, the tiny plants and animals on which bighead and silver carp typically feed, the lake has enough dietary options to sustain individual fish that venture away from nutrient-rich shoreline areas where most would congregate. That improves their prospects for colonizing large sections of Lake Michigan and eventually spreading to the other Great Lakes, said Peter Alsip, an ecological modeling data analyst and lead author of the paper published in the journal Freshwater Biology. Asian carp were imported in the late s to gobble up algae in Deep South sewage lagoons and fish farms.
