Only Small Number of Carp Needed For Foothold in Great Lakes

Sep 17, 2013

A new study cautions that even a small number of carp would be enough for the invaders to begin colonizing  the Great Lakes.

A paper published by scientist Kim Cuddington of the University of Waterloo in Ontario says models suggest a 50-50 chance  Asian carp could establish themselves  if just 10 find their way into one of the lakes.   The probability jumps to 75 percent, under certain conditions,  if 20 fish get through. Cuddington says it is not likely the bighead and siler carp can be kept out of the lakes forever.
