Northern Gannet - A Sentinel Species for the Gulf

cover of publication

The Northern Gannet is a seabird whose expansive feeding grounds and diet rich in fish can provide information on the abundance of its prey and the degree of contamination of the ecosystem; that is why it was chosen as a bioindicator of the state of the Gulf of St. Lawrence. After more than 30 years of prosperity, the gulf population is not doing as well since 2009, as colonies have started to decline and breeding success has considerably decreased. The underlying environmental factors responsible for this seem related to food availability, rather than exposure to contaminants.
