What is Seitakamaru?

　The fishing training vessel Seitaka Maru II was built in 62 by the Tokyo University of Marine Science and Technology, the predecessor of Tokyo University of Marine Science and Technology, for the purpose of educating marine personnel and providing practical training in oceanography and fisheries science.For about 3 years until her retirement in October 10, she used voyages for training and research purposes almost every month to conduct fishery resource surveys and oceanographic observations in Tokyo Bay and Sagami Bay.Many studies are still being conducted based on the data from the Seitaka Maru.
