Chlorine distribution over radial shell sections of marine (Anadara broughtoni from Peter the Great Bay, and Swiftopecten swifti), brackish water (Corbicula japonica from the Razdol'naya River estuaries), and freshwater (Margaritifera leana from the Razdol'naya River) was comparatively studied. The mean concentration of chlorine in the shells of investigated molluscs increased with increasing concentrations of chlorine in the environment.

Zeto, M. A. 1982. Notes on freshwater mussels (Unionidae) of the Upper Monongahela River Basin, West Virginia. The Nautilus 96(4):l27 l29.
During the spring and summer months of 1980, a preliminary survey of the freshwater mussels of the upper Monongahela River basin was conducted. A total of l5 species of the family Unionidae were found in various tributaries of the Monongahela River with only Corbicula fluminea being found in the mainstem of the river. Many of the species recorded (including C. fluminea) represent new records for this watershed.

A survey of the mussel fauna of Monroe County, West Virginia, was conducted during the spring of 1983 and 1984. This survey included samples from the Greenbrier River, Indian Creek, and South Fork of Potts Creek. Twelve species of unionid mussels and Corbicula fluminea were collected from these three watersheds, including a new state record. Canthyria collina, which is found in the South Fork of Potts Creek.

A preliminary survey of freshwater mussels inhabiting areas around the Ohio River islands of West Virginia was conducted in 1983 by the U.S. Fish and Wildlife Service, assisted by the West Virginia Department of Natural resources. The survey concluded that the Greeup and Belleville pools displayed a greater abundance and diversity of mussels than the remaining navigational pools along West Virginia, and warranted further investigation. During the spring and summer of 1985, numerous collections were made at various points within the two navigational pools to expand the data previously collected. Twenty four species of mussels and Corbicula sp. were collected from these areas, representing 16 and 23 species from the Greenup and Belleville pools, respectively. No species on the federal endangered species list were encountered, however four of the species collected are considered endangered by the State of Ohio.

Corbicula fluminalis is reported from northern Iran, Afghanistan, Mesopotamia, Syria, Baluchistan, Kashmir, India, Transcaucasia, and Middle Asia as well as Quaternary deposits in the USSR (Moldavian SSR [Dneister terraces], Ukrainian SSR) and the Apsheron layer of Pliocene deposits in the Betekei River, West Siberia. Corbicula fluminea is reported from the Amur liman to Poseta Bay, Sakhalin Island, and in general from the estuaries on the east and southeast coasts of Asia.

In freshwater bivalves such as the mussel Corbicula fluminea, uptake of chloride depends on the external concentration of the chloride ion. In C. fluminea, Cl- uptake displayed saturation kinetics both in animals acclimated to pondwater and in those subjected to salt depletion by storage in deionized water. The transport capacity (Jmax) was 7.00 ± 0.51 μeq g-1 dry tissue h-1 and the transport affinity (Km) was 0.21 ± 0.08 mM in animals acclimated to pondwater. Animals subjected to salt depletion had a higher rate of Cl- uptake than did animals acclimated to pondwater. After 4 weeks in deionized water, the longer the animals were salt-depleted, the higher their rate of Cl- uptake. Na+ and Cl- transport were independent in pondwater-acclimated C. fluminea. For salt-depleted animals, Cl- transport was Na+-independent, but Na+ transport depended partially on external Cl-. Serotonin stimulated Cl- and Na+ transport in pondwater-acclimated animals by increasing influx while having little influence on efflux. Acetazolamide increased the Cl- and Na+ efflux of salt-depleted animals. Both serotonin and acetazolamide elevated the net loss of titratable base.
Zheng, H. and T. H. Dietz. 1998. Paracellular solute uptake in the freshwater bivalves Corbicula fluminea and Toxolasma texasensis. Biological Bulletin 194(2):170-177.
Two species of freshwater bivalve were exposed to hyperosmotic solutions of various nonelectrolytes to compare the paracellular permeability of their gill epithelia. In Corbicula fluminea, exposure resulted in an elevation of blood solutes that was primarily due to dehydration. After 36 h of exposure, the concentration of Na in the blood decreased precipitously, and the nonelectrolyte accumulated. When lanthanum was added to the solution as a diffusion tracer, its electron-dense precipitate was rarely observed to penetrate the paracellular spaces of the gill epithelial cells in the absence of hyperosmotic stress. In contrast, precipitated lanthanum was commonly observed in the paracellular junctional complexes of the gill in animals that were subjected to hyperosmotic conditions. When the second species, Toxolasma texasensis, was exposed to hyperosmotic solutions of nonelectrolyte, dehydration appeared to be minimal and a seemingly normal concentration of ions was maintained in the blood. This, however, was because of the simultaneous loss of ions and water and a small gain in nonelectrolytes. Longer exposure (12 h or more) produced a precipitous decrease in most blood solutes and an extensive accumulation of nonelectrolyte. More lanthanum precipitate was seen in the paracellular spaces of both control and hyperosmotically stressed T. texasensis than in identically treated C. fluminea. We conclude that the epithelial junctions found in C. fluminea are relatively tight, which probably contributes to the ability of this species to maintain the solute in its body fluid at concentrations higher than are possible in T. texasensis.

In this study, an active protein, named CFp-a, was isolated and purified from the fresh C. fluminea with the methods of ammonium sulfate precipitation, Blue Sepharose 6 Fast Flow, SP Sepharose Fast Flow column chromatography and HPUC. Among them, Blue Sepharose 6 Fast Flow is a kind of affinity chromatography with Cibacron Blue F3GA as a ligand.

Ziebell, C. 1974. Removal of Phosphate and Secondary BOD from tertiary Treated Waste Water by Aquatic Animals. U. S. National Technical Information Service P. B. Report No. 225210/4gA.
Various organisms were tested for their ability to remove the orthophosphate ion from solution. After preliminary testing of fish, several aquatic plants, algae and clams, a system of natural algal succession and beds of the oriental clam Corbicula fluminea Müller was chosen. Experiments were conducted under controlled conditions at phosphate concentrations of 5.0, 10.0, and 15.0 mg/liter. The results indicated that this system can remove the phosphate ion to below 0.30 mg/liter in 16 days or less and yield a clear effluent acceptable for reuse. A potential fishery and possibly other water-based recreation appears feasible. originally this research was to be conducted with tertiary treated municipal wastewater, but completion of the city facility was delayed and consequently it was necessary to simulate 'wastewater' by adding phosphates and nitrates to local well water.
