Fishery production is an important source of income for many people across the world. Marine and freshwater fisheries provide jobs in local communities and is also important for trade in both developing and developed economies. Climate change and human activities pose a threat to the fish production by changing habitat quality. Changes in fish production have direct impacts on economic welfare (consumer and producer surplus) and the goal of fishery management is to improve both biological and economic fishery outcomes. This dissertation explores the relationship between fish production and various water quality indicators in the Estuary and Gulf of St. Lawrence (EGSL) and examines the economic impact of changes in water quality in fisheries. It examines the pathways through which water quality impacts fish stocks and subsequent impacts on harvest and economic welfare, and suggests policies for fishery management. Chapter one examines the impact of water quality in a marine fishery under regulated access. It particularly focuses on how hypoxia impacts welfare in a large fishery that has different degrees of hypoxia. Chapter two examines water quality in a freshwater fishery and focuses on the direct and indirect mechanisms through which nutrient pollution impacts fisheries. Finally, chapter three acts as an extension to chapter one, examining the impact of hypoxia on a marine species with an additional assumption that the impact of this water quality indicator may be different at different life stages, which may change the possible welfare impacts of variations in water quality.
