Visit the Asian Carp Overview page for more information on these fish.
The National Park Service is encouraging boaters to trailer boats around the locks instead of going through them. This will minimize the chance that Asian carp will pass through the locks and into uninfested waters. Please do your part to help stop these fish! For more information, click here.
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. For a list of other lakes and rivers newly designated as "infested waters", visit the MNDNR's website.
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) and Minnesota DNR Press Release for detailed information.
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.
Of the 50 samples taken on the 3.5 mile stretch of the Mississippi River:
Funding for the study has been provided by the Mississippi River Fund and St. Croix National Scenic Riverway Fund of the St. Croix Valley Foundation.
- All samples tested negative for bighead carp
- All samples tested negative for black carp
- 14 samples tested positive for silver carp
