Anne Hollowed of the Center's Resource Ecology and Fisheries Management Division served as co-convener and guest editor for the PICES/ICES/FAO international symposium on "Climate Change Effects on Fish and Fisheries: Forecasting Impacts, Assessing Ecosystem Responses and Evaluating Management Strategies" held on 2629 April 2011 in Sendai, Japan.

The response to the symposium exceeded the expectations of the conveners, with more than 350 abstracts submitted by scientists from more than 40 countries. In all, 208 talks and 105 posters were presented. Center scientists contributed to 22 oral presentations or posters. The symposium covered a wide range of topics and provided an opportunity for scientists to discuss the potential impacts of climate change on marine ecosystems and fostered international collaborative research efforts that will be needed to tackle the issues of climate change effects on fish and fisheries.

The symposium proceedings published in the 6 July 2011 issue of the ICES Journal of Marine Science provide a valuable assessment of our current knowledge of the effects of climate change on fish and fisheries. The papers illustrate the complexity and multifaceted issues facing the scientific community as they strive to understand and project the future implications of climate change effects on marine ecosystems. The volume provides the reader with a comprehensive understanding of the topics discussed during the symposium and the range of approaches being explored to assess the effects of climate change on fish and fisheries. Several papers address the implications of climate change and ocean acidification on the distribution and productivity of marine species under a changing climate.

Studies of adaptation and changes in phenology illustrated the importance of monitoring seasonal changes in temperature, acidification, and daylength on the physiology and timing of key life-history events. Other papers used ecosystem models to assess the direct and indirect impacts of climate change that would emerge through species interactions. Different methods for modelling the effects of climate change on fish and fisheries were presented and discussed. In the final papers, authors consider the human dimensions of climate change. These papers emphasized that analytical teams attempting to project the future of fisheries should include social scientists, stakeholders, and economists to project societal and market changes.

Symposium sponsors included The Fisheries Research Agency of Japan, Hokkaido University, Fisheries and Oceans Canada, Integrated Climate System Analysis and Prediction, Germany, Intergovernmental Oceanographic Commission of UNESCO, International Pacific Halibut Commission, Japan Society for the Promotion of Science, Korea Ocean Research and Development Institute, National Climate Change Adaptation Research Facility: Adaptation Research Network for Marine Biodiversity and Resources, National Institute of Environmental Studies Japan, National Marine Fisheries Service (NOAA), North Pacific Anadromous Fish Commission, North Pacific Research Board, Pacific Salmon Foundation, Scientific Committee on Oceanic Research, Sendai Tourism and Convention Bureau, and the World Bank.
