Symposium at the 144th AFS conference: marine mammals & fisheries interactions
We are responsible of a special symposium on Marine mammals & fisheries interactions during the American Fisheries Society 144th annual meeting, August 17-21 2014 in Québec City. A brief description of the symposia is provided below. Please send your abstract before March 7th, 2014 to lyne.morissette@globetrotter.net. Limited numbers of presentations are accepted, but we hope to have a wide variety of submissions so we can make this symposium and the discussions fruitful.

Hope to see you there!

Marine mammal and fisheries interactions : management challenges in a changing world.
Interactions between marine mammals and fisheries can be either direct (or operational), through bycatch, depredation and disturbance, or indirect (or ecological) through competition, trophic interactions, or habitat degradation. In both cases, this pose serious conservation challenges, and this has become an increasingly important topic in managing marine ecosystems and the species they support, resulting in new paradigms in fisheries management.
Direct interactions between marine mammals and fisheries pose some of the most serious and immediate threats to the animals and thus represent some important conservation challenges. Giving the current status of global fisheries, the chances of having marine mammals interacting with fishing gear is increasing. There are various way marine mammals can directly interact with fisheries, such as bycatch and depredation, and a lot of research is done to mitigate the problem.
Trophic interactions between marine mammals and fisheries have been the subject for considerable research during the last decade. However, the extent to which the issue is addressed in an ecosystem, a multi-species context, is still limited. Consequently, there is still a lack of unequivocal evidence for competition between marine mammals and fisheries on a global scale. This may be due to (1) the absence of appropriately scaled information on marine mammals’ diet and ecology; (2) the lack of consideration of all trophic groups in the ecosystems where these interactions might happen or (3) the indirect effects being more important than initially thought in foodwebs.
The aim of this symposia is to present an update on our knowledge of direct and indirect interactions between marine mammals and fisheries, to bring fisheries scientists and marine mammal experts together and discuss ideas on how to adapt to these issues in a time of changing marine ecosystems.
