  1. Small pelagic fish responses to future climate change Shin-ichi Ito & Takeshi Okunishi (FRA) Reviewed fish responses to future climate change. Ito S. et al. (2010) Ocean ecosystem responses to future global change scenarios: A way forward, In: M. Barange, J.G. Field, R.H. Harris, E. Hofmann, R. I. Perry, F. Werner (Eds) Global Change and Marine Ecosystems. Oxford University Press., 287-322, pp440. Recently published several papers relating fish responses to future climate change. Ito S., T. Okunishi, M. J. Kishi and M. Wang (2013) Modelling ecological responses of Pacific saury (Cololabissaira) to future climate change and its uncertainty, ICES J. Mar. Sci., 70, 980-990. Yatsu A., S. Chiba, Y. Yamanaka, S. Ito, Y. Shimizu, M. Kaeriyama, and Y. Watanabe, 2013, Climate forcing and the Kuroshio/Oyashio ecosystem, ICES J. Mar. Sci., 70, 922-933. Okunishi T., S. Ito, T. Hashioka, T. T. Sakamoto, N. Yoshie, H. Sumata, Y. Yara, N. Okada, Y.

  2. Ito S., T. Okunishi, M. J. Kishi and M. Wang (2013) Modelling ecological responses of Pacific saury (Cololabissaira) to future climate change and its uncertainty, ICES J. Mar. Sci., 70, 980-990.cv 30 cm Distribution of Pacific saury in June-July 2007 (FRA surface trawl survey) Catch of Pacific saury Ito et al. (2013) Pacific saury widely distribute in the North Pacific. It is exploited in several countries and an international fish.

  3. NEMURO.FISH NEMURO for Including Saury and Herring nutrient zoo phyto fish Megrey et al. (2007a, Ecol. Model.), Ito et al. (2004b Fish. Oceanogr.) etc.

  4. Ensemble experiment with 12 IPCC-SSTs (A1Bsenario) wet weight of saury • Control run (1950-1999) Ito et al. (2013, ICES J. Mar. Sci.) 3 categories 1) reduction of weight in the 1st and 2nd years ccsm3, gfdl20, mirocH, mirocM, mpi, ukhadcm3 2) reduction of weight in the 2nd year cccmat47, cccmat63, gfdl21, miub 3) no decrease (or increase) of weight pcm1, mri

  5. Dependency on emission scenarios 3 emission scenarios Saury decreased their weight in 24 cases in 33 cases (73%). Egg production was enhance in 11 cases in 33 cases (33%) Ito et al. (2013, ICES J. Mar. Sci.)

  6. Ensemble experiment with only SST forcing A1B With future SST & current zooplankton • Control run (1950-1999) no decrease in second year SST effects only on juvenile’s growth. 2 categories reduction of weight in the 1st year ccsm3, gfdl20, mirocH, mirocM, mpi, ukhadcm3 no decrease or increase of weight cccmat47, cccmat63, gfdl21, miub, pcm1, mri Ito et al. (2013, ICES J. Mar. Sci.)

  7. Yatsu A., S. Chiba, Y. Yamanaka, S. Ito, Y. Shimizu, M. Kaeriyama, and Y. Watanabe, 2013, Climate forcing and the Kuroshio/Oyashio ecosystem, ICES J. Mar. Sci., 70, 922-933. Published contributions of CFAME activity. Summarize the climate effects on the Kuroshio/Oyashio ecosystems.

  8. Spawning grounds of Japanese sardine Okunishi et al. (2012), Climatic Change Control-RUN CO2-RUN Fig. Proportion of hatched numbers in the four spawning regions Projection Spawning grounds shifts to north-eastward. Area-1 Area-2 Area-3 Area-4 Spawning regions
