Report on the viability of using MOE index plankton samples to evaluate BUI : degradation of phytoplankton and zooplankton populations for Toronto region area of concern Report on plankton surveys related to the Thunder Bay AOC [Ottawa] : Fisheries and Oceans Canada, c2015. v, 152 p. : fig., graphs, maps, photographs, tables Canadian technical report of fisheries and aquatic sciences, 1488-5379 ; 3150 Includes bibliographical references. This report collects all available data from past literature and unpublished DFO surveys, in three sub-reports, on two Areas of Concern (AOC) designated requires further assessment for the Beneficial Use Impairment (BUI 13): “degradation of phytoplankton and zooplankton populations”. Toronto Region and Thunder Bay AOC are data-poor, with no active plankton sampling programs. A single 2013 Toronto survey coincided with a large upwelling, with plankton densities lower than expected within Toronto Harbour, matching results from past surveys. MOECC Index archived plankton samples were counted, but were insufficient to evaluate BUI 13 due to high variability and sparse sampling. A minimum six samples annually are required to determine species composition. Plankton data are documented for Thunder Bay and Superior, but no samples were available for impacted areas near the Kaministiquia River and inner Thunder Bay Harbour. gccst Lakes gccst Microorganisms gccst Environmental management Currie, W.
