Spatial Ecology of Open Systems, Part 1*

Wednesday, August 20, 2014: 10:30 AM-3:10 PM
2101 (Centre des congrès de Québec // Québec City Convention Centre)
Spatial ecology of fish is not only important for basic ecological understanding but also for fisheries management and conservation. Fish move, aggregate and disperse in relation to the physical environment, food supply, predators, spawning and social behaviours. Much of our thinking on spatial ecology of fish is premised around the idea of a closed system yet all ecosystems are open to varying degrees. This symposium aims to collect studies from a wide variety of marine and freshwater systems which elucidate the use of space and ecological mechanisms behind fish movements and population spatial distribution. Papers which deal with management aspects (fisheries and conservation) related to this understanding are particularly sought. Topics of study could include but are not limited to:

Methods for spatial analysis and spatial assessment of fish populations

Habitat dependence and fidelity (ontogenetic changes, reactions to habitat changes)

Climate change and fish movements at both small and large scales

Aggregation behaviours, range shifts and fisheries catchability

Development of spatial planning management based on knowledge of fish spatial ecology for both single and multiple species

Sub-population structure and impacts on recruitment, survival and population decline and recovery including multispecies interactions.
