|Improving Understanding of Past, Current and Future Direct and Indirect Effects of Grey Seal Predation on Transboundary Groundfish Stocks
The increasing abundance of Grey Seals over the past several decades has been linked to observed increases in the natural mortality rates of several exploited fish stocks in eastern Canada. To more accurately estimate fish stock size and avoid unreliable projections concerning the impact of harvesting or recovery strategies on fish populations, long-term trends in natural mortality rates need to be taken into account. This project will use ex...

|Ocean Acidification in the Arctic: Drivers and Impacts
In the Arctic Ocean, the acidification of surface waters has already reached the critical level for marine organisms that form shells and skeletons of calcium carbonate (CaCO3 ). Although ocean acidification is a global issue, polar oceans are inherently more vulnerable to it than temperate oceans due to the higher solubility of carbon dioxide and dissolution of CaCO3 in cold waters. Rapid environmental change in recent years—i...

|Evaluating the Role of Bottom-up Effects of Prey Availability on the Survival and Local Abundance of Atlantic Salmon
Poor marine survival of Atlantic Salmon has led to about a 70 percent decline in abundance since 1970. Though the causes are not well understood, observed differences in survival between two types of spawners from the Miramichi River may provide a clue. Survival for repeat spawners that spend less than a year at sea has been relatively good and appears to be related to possible feeding success in the Gulf of St. Lawrence. In contrast, surviva...

|Effects of Changing Oceanographic Conditions and Competition on the Survival and Growth of Sockeye, Pink, and Chum salmon in the North Pacific Ocean: Implications for National and International Fisheries Assessment and Management
Populations of Pacific salmon are widely distributed throughout the North Pacific Ocean and intermingle and compete with each other regardless of their country of origin. Overall, the abundance of salmon in the North Pacific is at an all-time high due to a combination of generally favourable climate and large releases of hatchery origin salmon, mostly from Alaska and Asia. In recent years, returns of certain Canadian populations of salmon hav...
