Demographic models as tools to assess vulnerability and resilience of marine stocks to environmental and fishing pressures
Measuring the vulnerability and resiliency of fish stocks to both environmental and fishing effects can be used to efficiently manage harvesting rules and rebuild collapsed stocks. These measurements are based on the productivity of individual fish stocks, which can be affected by changes in ecosystem composition (e.g., changes in the abundance of predators) and environmental conditions (climate). This project will use demographic models with northern Gulf of St. Lawrence cod as a case study to evaluate the vulnerability and resiliency of exploited species under different environmental conditions and harvesting strategies. It will also develop operating models to simulate population productivity and abundance under different scenarios and eventually extend the study to other fish stocks.
