Book Fresh Water Mussels Mollusca Bivalvia Unionidae of the Upper Mississippi River Observations at Selected Sites Within the 9 Foot Channel Navigation Project on Behalf of the U S Army

Download or read book Fresh Water Mussels Mollusca Bivalvia Unionidae of the Upper Mississippi River Observations at Selected Sites Within the 9 Foot Channel Navigation Project on Behalf of the U S Army written by Samuel L. H. Fuller and published by . This book was released on 1978 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey of freshwater mussels of the Upper Mississippi River drainage was conducted during the summer and autumn of 1977. Over 8,000 living specimens were gathered and examined during surveillance of more than 40 actual and/or potential dredging sites in the Minnesota and St. Croix Rivers and in almost 20 Upper Mississippi River pools. Dredging and associated activities to maintain the 9-foot navigation channel has caused local mortality of mussels, including endangered species. There are other factors having far greater adverse impact, including wastes from the cities of Minneapolis and St. Paul, agricultural runoff, impoundment of the Upper Mississippi River and encroachment by Corbicula fluminea, the Asiatic Clam. The outlook for a continuing ecosystematic and commercial mussel resource appear to be good. Even certain endangered species (e.g. Lampsilis higginsi) are likely to survive if appropriate measures are taken.

Book Effects of Increased Commercial Navigation Traffic on Freshwater Mussels in the Upper Mississippi River Ten Year Evaluation

Download or read book Effects of Increased Commercial Navigation Traffic on Freshwater Mussels in the Upper Mississippi River Ten Year Evaluation written by and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 198Os the U.S. Army Engineer District, St. Louis, requested that the U.S. Army Engineer Waterways Experiment Station, now part of the Engineer Research and Development Center, in Vicksburg, MS, conduct studies on the physical and biological effects of commercial navigation traffic at five historically prominent mussel beds in the upper Mississippi River (UMR). The purpose was to assess effects of increased navigation traffic caused by the newly completed Melvin Price Locks and Dam at Alton, IL. Studies were initiated in 1989 and conducted annually until 1994 when they were to be done every fifth year until 2040. This report describes results of studies conducted in 1999 at three of the mussel beds located in Pool 10 (River Mile (RM) 635), Pool 14 (RM 504.8), and Pool 24 (PM 299.6). In previous years, mussel beds at RM 450.4 (Pool 17) and RM 571.5 (Pool 12) were also studied. Because of recent concern over effects of zebra mussels (Dreissenapolymorpha) on freshwater mussels, data collected in 2000 and 2001 on this species have also been included. In 1999, 26 species of bivalves, including the Asian clam, Corbiculaflurninea. were collected at the three beds in the UMR using qualitative methods. Overall, the fauna was dominated by Amblemaplicata; this species comprised more than 60 and 40 percent of the fauna in Pools 10 and 14, respectively. Ellipsaria lineolata was the dominant freshwater mussel at the mussel bed in Pool 24. The endangered Lainpsilis higginsi was found in Pool 10 (1.72 percent of the assemblage) and Pool 14 (2.44 percent of the assemblage). It was not found in Pool 24, which is outside its range.

Book Freshwater Mussels Mollusca Bivalvia Unionidae of the Upper Mississippi River Observations at Selected Sites Within the 9 Foot Navigation Channel Project for the St Paul District United States Army Corps of Engineers 1977 1979 Volume I Text

Download or read book Freshwater Mussels Mollusca Bivalvia Unionidae of the Upper Mississippi River Observations at Selected Sites Within the 9 Foot Navigation Channel Project for the St Paul District United States Army Corps of Engineers 1977 1979 Volume I Text written by Samuel L. H. Fuller and published by . This book was released on 1980 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objectives of the study were to characterize the present mussel fauna, to compare it to the fauna existing before the 9-foot Navigation Channel Project, and to determine the influence(s) upon mussels by practices of the District's Operations and Maintenance (O & M) activities. The study area was the main channel and main channel borders of the UMR itself from Head of Navigation at river mile (RM) 857.8 in the Twin Cities, Minnesota, to Locks and Dam 10 at Guttenberg, Iowa (RM 615.1), and the lowermost (Corps-maintained) reaches of the black (at La Crosse, Wisconsin), Minnesota, and St. Croix rivers. More than 100 formal Sites were thoroughly surveyed (usually by brailing), and about a dozen locations were investigated cursority. Over 10,000 living mussels were collected and examined, including a few of the Endangered Lampsilis higginsi.
