The DNR has officially announced the infestation of waters south of Lock and Dam No. 2 on the Mississippi River by bighead and silver carp. Due to the confirmed presence of Asian carp, it is now illegal to harvest bait and transport water from this area of the river. Visit the Minnesota Department of Natural Resources website for a list of infested waters.
Mississippi River testing confirms presence of silver carp DNA as far up as Lock and Dam No. 1. Of the 50 samples gathered downstream of the dam, 14 tested positive for presence of silver carp DNA. See the sampling map (PDF, 1.1mb)
On June 28 and June 29, 2011, eDNA Solutions, Inc. conducted environmental DNA (eDNA) testing in the St. Croix and Mississippi rivers for Black, Bighead and Silver carp. Testing on the St. Croix occurred from below the dam at Taylors Falls and continued 4.3 miles downstream. The testing on the Mississippi covered a reach from immediately below low Lock and Dam No. 1 (Ford Dam) to the mouth of the Minnesota River about 3.5 miles downstream. See the report, eDNA Surveillance of Asian Carp on the St. Croix and Mississippi River (PDF, 500kb) for detailed findings.
