Survey, Ecology, and Systematics of the Upper Potomac Estuary Biota: Aufwuchs Microfauna. Phase III

摘要

These studies utilized two adjacent bench scale rivers, each composed of four interconnected 24-gallon aquaria, stimulating summer flow and temperature (30 degrees C) of the fresh water estuarine Potomac River from Hains Point to Piscataway Creek. Initially all eight aquaria were seeded with the filamentous blue-green alga, Anabaena. To all aquaria was added a mixture of Daphnia, copepods, and ostracods from a swamp near Little Falls. (Preliminary studies showed these zooplankters could remove the Anabaena.) The experimental side received activated sludge from the Blue Plains Sewage Treatment Plant, while the control received dechlorinated tap water.
