抄録

We carried out a questionnaire survey at fishery co-operative associations which exist all around Japan to obtain information on the distribution of ocellate puffer, Takifugu ruburipes. The result showed that ocellate puffer were caught in the Yellow and East China Seas, and in all waters off Japan other than the Nemuro straits, waters off the Izu Ogasawara Islands and the Nansei Okinawa Islands. It was estimated from the amount of catch and state of the puffer fishery that the main distribution area of puffer was in the Japan Sea south of Aomori Prefecture and in the Pacific Ocean south of Miayagi Prefecture, around the Seto Inland Sea, and in the Yellow and East China Seas. Comparing the fishing grounds and seasons in which the puffer were caught, the puffer distributed in its major distribution areas from autumn to early spring, and then migrate from thier feeding areas to the spawning ground from spring to early summer (around the spawning season) which occur in areas except Hokkaido. Some areas that have both spawning grounds and high catch rate occur in a discontinuous pattern around Japan. This suggesed the possibility that the ocellate puffer distributed around the seas off Japan was composed of several sub-populations.
