abstract
Salmon aquaculture in Cobscook Bay, Maine, contributes significantly to the economy of both the US and Canada. However, the increasing density of salmon pens leads to questions about sustainable levels of aquaculture in the bay because of concerns about nutrient loading and the potential for eutrophication associated with point sources of fish wastes and unconsumed fish feed. The central questions relate to the significance of aquaculture-related nutrient sources compared to natural ones, and the capacity of the tides to flush the bay of pollutants and waste products. To address these issues, a thorough understanding of the extent to which the tidal circulation is able to flush pollutants from the bay is critical.
