Climate Change Effects - A2 Presentations- PICES

Co-Convenors: Richard Beamish (Pacific Biological Station, DFO, Canada) Myron Peck (Center for Marine and Climate Research, University of Hamburg, Germany) Motomitsu Takahashi (Seikai National Fisheries Research Institute, FRA, Japan)

Climate is now recognized as a major factor affecting the productivity of key species in world fisheries. The mechanisms that link climate to fish productivity need to be better understood to ensure that natural and greenhouse gas induced climate changes are incorporated into the management of fisheries. Population-level changes in commercially and ecologically important marine fish species may result from climate-driven changes in organismal-level vital rates (e.g., changes in growth, reproductive success and mortality). Furthermore, expansion, contraction and/or shifts in the distribution of fish stocks will result from changes in suitable habitats (habitats that allow connectivity among life stages, life cycle closure and successful recruitment). The extent of climate-driven changes will be mediated by the capacity for individual species (or populations) to adapt to changes in important abiotic and biotic factors. Adaptations could include both changes in the phenology of important life history events (e.g., migration, spawning) and/or physiological changes (e.g., thermal reaction norms of key traits such as growth, increased tolerance to lowered pH/ocean acidification). This session provides a forum for presentations focusing on the response of key fish and fisheries species worldwide to climate change by: (1) documenting historical, long-term fluctuations in abundance and distribution, (2) discussing processes underlying current changes, and/or (3) projecting future impacts in light of adaptive capacity. Key fisheries species include those utilizing marine habitats during any portion of their life cycle and that are commercially or ecologically important marine resources.
