This book was released on 1999 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surveys were conducted in August 1998 to assess community characteristics, population demography of dominant species, status of endangered species, and characteristics of nonindigenous populations of freshwater bivalves in the lower Ohio River (LOR). Data will be used to analyze ecological effects of construction and operation of a new lock and dam at River Mile (RM) 964.4. Primary focus has been on a prominent mussel bed just downstream of the project at Olmsted, Illinois. Studies have shown that this mussel bed extends approximately from elevation 278 ft nearshore to 267 ft farshore. Moderate (20-50 individuals per square meter) or high density (>50 individuals per square meter) assemblages of mussels tend to be at more central elevations on the bed from approximately RM 966.4 to 968.3.

This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surveys were conducted in the summers of 2000 and 2001 to assess community characteristics, population demography of dominant species, status of endangered species, and characteristics of nonindigenous populations of freshwater bivalves in the lower Ohio River. Data will be used to analyze ecological effects of construction and operation of a new lock and dam at River Mile (RM) 964.4. Primary focus has been on a prominent mussel bed just downstream of the project at Olmsted, IL. Studies have shown that this mussel bed extends approximately from elevation 278 ft nearshore to 267 ft farshore. Moderate (20 to 50 individuals/sq m) or high density (>50 individuals/sq m) assemblages of mussels tend to be located at more central elevations on the bed from approximately RM 966.4 to 968.3. The downstream and farshore limits of the mussel bed tend to be less distinct than the nearshore and upstream limits. The community downstream of the project is extremely dominated by Fusconaia ebena. A mussel bed being monitored upstream of the project, at RM 957 near Post Creek, is clearly dominated by this species, but much less heavily than at Olmsted. Also, the abundance of F. ebena is higher farshore than nearshore at the Post Creek site. Communities at both Olmsted and Post Creek have been resilient to long-term occurrence (since approximately 1960) of the Asiatic clam, Corbicula fluminea, and more recent occurrence of the zebra mussel, Dreissena polymorpha. Both mussel beds are characterized by extreme dominance of a few year classes (especially 1981, 1990, and 1998) of the dominant species. Rapid spring rises in discharge from unseasonally low values occurred in combination with rising water temperatures in spring of all three good recruitment years. These conditions may trigger spawning runs by F. ebena's host fish, Alosa chrysochloris (skipjack herring).

This book was released on 2001 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surveys were conducted in late July and early August 1999 to assess community characteristics, population demography of dominant species, status of endangered species, and characteristics of nonindigenous populations of freshwater bivalves in the lower Ohio River (LOR). Data will be used to analyze ecological effects of construction and operation of a new lock and dam at River Mile (RM) 964.4. Primary focus has been on a prominent mussel bed just downstream of the project at Olmsted, IL. Studies have shown that this mussel bed extends approximately from elevation 84.7 m (278 ft) nearshore to 69.2 m (267 ft) 2 2 farshore (elevations referred to mean seal level). Moderate- (20-50 individuals sq m) or high- (> 50 individuals sq m) density assemblages of mussels tend to occur at more central elevations on the bed from approximately RM 966.4 to 968.3. The downstream and farshore limits of the mussel bed tend to be less distinct than the nearshore and upstream limits. The community downstream of the project is extremely dominated by Fusconaia ebena. A mussel bed being monitored upstream of the project, at RM 957 near Post Creek, is clearly dominated by this species, but much less heavily than at Olmsted. Also, the abundance of F. ebena is higher farshore than nearshore at the Post Creek site. Communities at both Olmsted and Post Creek have been resilient to long-term occurrence (since approximately 1960) of the Asiatic clam, Corbicula fluminea, and more recent occurrence of the zebra mussel, Dreissena polymorpha. Both mussel beds are characterized by extreme dominance of just two year classes, 1981 and 1990, of the dominant species. Demographically complete sampling of F. ebena (Lea) at Olmsted was conducted from 1983 through 1999. Dominance of the 1981 and 1990 cohorts allowed length-to-age relationships to be estimated directly from length-frequency histograms. Two linear relationships adequately described growth rates from ages 2 through 17 years.

Book Synopsis The Freshwater Mussels of Ohio by : G. Thomas Watters
Download or read book The Freshwater Mussels of Ohio written by G. Thomas Watters and published by . This book was released on 2009 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early nineteenth century, a naturalist named Rafinesque stood on the banks of the Ohio River and began to describe the freshwater mussels he found there. Since that time, these animals have earned a place among the most imperiled animals in North America. Dozens of species have become extinct, and it is estimated that two-thirds of the remaining freshwater mussels face a similar fate. Yet, despite their importance, the mussels of Ohio remain a poorly documented and largely mysterious fauna. This book compiles existing research on Ohio's mussels, synthesizing works on genetics, biology, and systematics into one volume. Full-page color images depict shell variation, hinge detail, and beak sculpture. Full-page maps show the distribution of each species based upon the collections of numerous museums, with historical distributions dating from the 1800s. In addition to species accounts, the book has an introductory section that includes information on basic biology, human use, and conservation issues.--adapted from jacket.
Book Synopsis A Survey of the Freshwater Mussels of the Lower Cumberland River from Barkley Dam Tailwater Downstream to the Ohio River by : James B. Sickel
Download or read book A Survey of the Freshwater Mussels of the Lower Cumberland River from Barkley Dam Tailwater Downstream to the Ohio River written by James B. Sickel and published by . This book was released on 1982 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 9 September through 8 November, 1981, a survey of freshwater mussels (Mollusca: Bivalvia: Unionidae) was conducted to determine the species, location, relative density and habitat characteristics of mussels inhabiting the Barkley Dam tailwaters. Boats, equipped with 16 ft. mussel brails, were used to determine the locations and species composition of mussel beds, and scuba divers examined the beds to better sample the mussel fauna and determine sediment characteristics. Proposed dredging and disposal sites were examined to estimate the potential impact of Corps' navigation improvement activities upon the mussels. Twenty-one species of mussels in 16 general still survive in the lower Cumberland River. Mussel beds were found only in stable habitats which have probably been undisturbed for many years and which consist of gravel in a firm sandy-clay. Extreme daily fluctuations in discharge through the dam and high silt may have an adverse influence on reproduction and host fish distribution. Because the potential impact of dredging operations on downstream mussel beds is not known, it is recommended that a monitoring program be established to evaluate such impact.
Book Synopsis A Survey of the Freshwater Mussels of the Ohio River from Greenup Locks and Dam to Pittsburgh, Pennsylvania by : Ralph W. Taylor

This book was released on 1980 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the months of May-September 1979 the Ohio River, from its origin at Pittsburgh, Pennsylvania to the Greenup Locks and Dam, Greenup, Kentucky, was surveyed in order to document the extant freshwater mussel fauna. This was accomplished by a team of biologists from Marshall University traveling the river in a sixteen foot bass boat powered by a fifty horsepower outboard motor. The river was traversed at approximately five miles per hour until either likely looking habitat or shell debris was spotted. Sighting of shell deposits was aided by using binoculars to scan the shore line. In either case, as shells were discovered the boat was beached and collections were made. All shells, old and new, were collected from the beaches, bagged and tagged with locality data and later returned to the laboratory for sorting and identification. Many additional shells were also hand picked from shallow waters. By virtue of the fact that mussels were already in short supply, very few live specimens were removed from the river. For the most part live specimens were collected, identified and returned to the water. Many sites were brailed, using a six foot sampling brail, but for the most part brailing proved unsatisfactory as there was so much debris on the river bottom that we spent more time cleaning the brail than we spent brailing. Upon returning to the laboratory specimens were cleaned, labeled, aged, cataloged and classified as to whether they were without a doubt distinctly fresh or whether they were sub-fossils. The total number of species identified was 35. Of this number eight were found only as sub-fossil shells and must be presumed to be presently extinct or very nearly so in this research of the river.
