General report on the projects aided by the PICES/ICES/JSFO fund for fisheries
and oceanographic research on the recovery from the Great East JapanEarthquake
Hiroya Sugisaki on behalf of Japanese Society of Fisheries OceanographyFisheries Research Agency, sugisaki@affrc.go.jp
Just after the Great East Japan Earthquake occurred on the 11th of March, 2011, PICES (North Pacific Marine ScienceOrganization), ICES (International Council for the Exploration of the Sea) offered a donation of CDN$55100 to a research fund forJapanese scientists. The Japanese Society of Fisheries Science (JSFO), as the secretariat of this fund, added ca. CD$7400 and accepted
applications for research projects and selected 11 projects, mainly from the local institutes and universities of Northeastern Japan(Tohoku area; Iwate, Miyagi and Fukushima prefectures)

Many local institutions of fisheries and oceanography
has been damaged by the earthquake and tsunami.
PICES/ICES/JSFO fund supported to recover their scientific activities
especially for research on the effect of the fishing villages and ecosystems
of northeastern Japan (Tohoku region).
