"This study identifies plankton communities impairments within the Toronto and Region Area of Concern (AOC) to determine food resources for forage fishes in different habitats to support an assessment of Beneficial Use Impairment (BUI) 13 (Degradation of Phytoplankton and Zooplankton Populations) and provide georeferenced habitat data for BUI 14 (Loss of Fish and Wildlife Habitat). Water quality, zooplankton abundance and biomass differed across habitat ecotypes, with Inner Harbour exhibiting very low biomass similar to the open waters of Lake Ontario and a higher proportion of small taxa like rotifers, in spite of elevated nutrients"--Abstract, page ix.
