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.

This book was released on 1982 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large river systems are valuable national resources that provide numerous benefits to travel, shipping, recreation, and fish and wildlife. However, efforts to expand one of the uses frequently come in direct conflict with one or more of the othersThis guide attempts to bring together all scientific data that are available on techniques that have been or can be used to offset or reduce the impacts of development and maintenance of Upper Mississippi River System or other large river systems. Decision makers are thus provided an objective descriptin of options now at their disposal when they attempt to weigh the merits of defects associated with a particular action.

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.

This book was released on 1997 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey to assess community characteristics, density, population demography of dominant species, and the presence of rare or endangered species of mussels (Family: Unionidae) was conducted in selected reaches of the Quiver River and Bogue Phalia, Mississippi, in 1994 and 1995 for the U.S. Army Engineer District, Vicksburg. Results are being used to assess the economic value of mussels in the project area and to determine the environmental effects of proposed maintenance dredging. The project area included a section of the Quiver River between its confluence with the Big Sunflower River immediately north of Highway 82 in Sunflower County to the Leflore-Tallahatchie county line. In the Bogue Phalia, the study area consisted of a reach between Highway 82 and Rosedale, west-central Bolivar County. Twenty-two species of native freshwater mussels were collected in the Quiver River; 26 sites were sampled using qualitative methods, and a total of 2,238 mussels were collected. The dominant mussel was Amblema p. plicata, which comprised over 67 percent of the mussel fauna. Plectomerus dombeyanus comprised 20 percent of the mussels. Overall species diversity (0.67 to 0.90) was low, mainly because of the dominance of A. p. plicata. Evidence of recent recruitment was low; approximately 7 percent of the species and 0.15 percent of the individuals collected were less than 30 mm total shell length. Overall mean density ranged from less than 8.6 individuals/square meter at River Mile (RM) 6.4 to 92.3 individuals/square meter at RM 19.7.

This book was released on 1995 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1988, the U.S. Army Engineer District, St. Louis, initiated a monitoring program to analyze the effect of commercial navigation traffic on freshwater mussels (Mollusca: Unionidae), especially the endangered Lampsilis higginsi, in the upper Mississippi River (UMR). Preliminary studies were conducted in 1988, and detailed studies were initiated in 1989 and continued until 1994. In July 1994, the last year of this study, qualitative and quantitative data (0.25 m2 total substratum samples) were collected at the following locations: Pool 24 (River Mile (RM) 299.6), Pool 17 (RM 450.4), Pool 14 (RM 504.5), Pool 12 (RM 571 A), and Pool 10 (RM 635.2, main channel). This research was funded by the U.S. Army Engineer District, St. Louis, to assess the effects of existing and projected future increased navigation traffic levels on freshwater mussels, including the endangered Higgins eye mussel, Lampsihs higginsi. A total of 26 species of bivalves were collected, including two exotic species, the Asiatic clam, Corbicula flumi-flea, and the zebra mussel, Dreissena polymorpha. During this study year, zebra mussels were still a minor component of the bivalve assemblage; density ranged from 0.27 +/- 0.13 at RM 299.6 to 8.2 +/- 1.29 individuals/m2 at RM 504.8. Based on quantitative samples at five beds, species diversity ranged from 1.78 to 2.28, and total species richness ranged from 16 to 20. The percentage of native bivalves less than 30-mm total shell length, evidence of recent recruitment, was approximately 30 at all sites except in Pool 10 at RM 635.2 where it was only 12.8. The percentage of species that were evidence of recent recruitment ranged from a low of 43.7 at RM 299.6 to 60.0 at RM 571.5.
