Understanding Complex Linkages Between Fish and Fisheries in a Changing Ocean

Tuesday, August 21, 2012: 1:15 PM-3:00 PM
Meeting Room 6 (RiverCentre)
Fisheries scientists have long recognized that fish abundance is strongly influenced by conditions in the natural environment, and for exploited populations, by the direct influence of humans through fishing.  Environmental conditions encompass both the physical environment as well as ecological properties including the abundance of predators and prey.  Predator-prey relationships create dynamical linkages between fish populations.  Fishing which is influenced by environmental conditions as well as economics and regulations introduces another set of complex dynamics that can link seemingly separate fisheries.  Understanding how changes in one exploited population propagate to other components of the ecosystem is a key requirement for fisheries management to move towards an ecosystem approach.  This symposium aims to explore how linkages among fish populations and between fisheries ecosystems and socio-economic systems influence the dynamics of fish populations around the world.
