Limitation by iron of phytoplankton from the open waters of Lake Erie [electronic resource] / Michael R. Twiss, Jean-Christian Auclair & Murray Charlton. Burlington, Ont. : National Water Research Institute, 1997. 16 p. : ill. NWRI contribution ; 97-124 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Experiments in Lake Erie during 1996 indicated that algae growth was limited by iron availability. This is important because the algae are usually thought to be limited by phosphorus. The phosphorus limitation phenomenon is so well accepted that fishing interests are beginning to suggest that waning fish production is a sign that phosphorus controls under the Great Lakes Water Quality Agreement went too far"--Management perspective. gccst Water quality gccst Water pollution Auclair, J.
