New Onalaska genetics lab to help detect Asian carp

The U.S. Fish and Wildlife Service have made the Whitney Genetics Laboratory to test environmental DNA or eDNA so it can provide an early indication if the Asian carp might be lurking in certain waterways. The plankton-eating, fast-growing, non-native carp threaten to devastate the Great Lakes’ fishery and ecosystem.The eDNA comes from the scales of the fish.  To avoid contamination the samples have to be processed in careful conditions and have to be "cleaned" of other DNA. Even though test come out positive it doesn't mean that the crap was in the water.  eDNA can be carried in by birds, bilge water and dead fish downstream. The  lab which cost more than $1 million to build and equip.
