Book Description
Six government partners - Environment Canada, Fisheries and Oceans Canada, the Canadian Space Agency, Parks Canada Agency, the Ministère du Développement durable, de l'Environnement et des Parcs du Québec, the Ministère des Ressources naturelles et de la Faune du Québec - and Stratégies Saint-Laurent, a nongovernmental organization that works actively with riverside communities, are pooling their expertise and efforts to provide Canadians with information on the state of the St. Lawrence and long-term trends affecting it. To this end, environmental indicators have been developed on the basis of data collected as part of each organization's ongoing environmental monitoring activities. This fact sheet illustrates why the Northern Gannet, a seabird whose expansive feeding grounds and a diet rich in fish can provide information on the abundance of its prey and the degree of contamination of the ecosystem, was chosen as a sentinel species (or "bioindicator") of the state of the Gulf of St. Lawrence.

Lawrence, from In the 2012 survey of Great Blue Heron colonies, Lake Saint-François, upstream, to Sept-Îles and the average number of young per clutch was the Magdalen Islands in the Gulf (Figure 1). [...] In 2011, the following colonies were sampled: Île aux Hérons and Grande-Île, in the fluvial section; Île aux Basques, in the lower estuary; and Île Manowin, in the Gulf. [...] The eggs are kept cool and sent to the laboratory to be analyzed for mercury,1 PCBs,2 organochlorine pesticides (e.g., DDT3),PBDEs4 and sometimes dioxins and furans.5 Due to fluctuations in the size and presence of colonies, it is sometimes difficult to monitor the same colony over a long period. [...] The contaminant concentrations show few concentrations of total PBDEs in Great Blue Heron eggs were on the same order of magnitude 3.5 as those of DDE and PBDE concentrations measured 3 (11) in Herring Gull eggs from (7) the Great Lakes.
