The Role of Marine Mammals in the Ecosystem

 

For 1995, the Scientific Council initiated this Special Session titled 'The Role of Marine Mammals in the Ecosystem', as a Symposium of topical interest to NAFO. The Council invited International Council for the Exploration of the Sea (ICES) to co-sponsor the Symposium. The Joint NAFO/ICES Symposium was hosted by the NAFO Scientific Council at the NAFO 17th Annual Meeting held at the Holiday Inn, Dartmouth, Nova Scotia, Canada. This volume of the Journal of Northwest Atlantic Fishery Science contains papers presented at the Symposium. The Symposium was jointly convened by G. B. Stenson (Canada-NAFO) from the Northwest Atlantic Fisheries Centre, St. John's, Newfoundland, Canada, and J. Sigurjónsson (Iceland-ICES) from the Marine Research Institute, Reykjavik, Iceland. A total of 51 papers and posters were presented of which 26 papers were submitted by the authors for consideration for publication in this issue.
