Abstract

Long-term change of Ohata fishing port, famous as a landing port of squid in northern Honshu, was investigated by data-mining method of past photographs showing various activities at the port. Harbor structures have been constructed responding to the increase of landing of squid. However, when these infrastructures were completed, the amount of catch of squid largely declined, leaving large-scale harbor structures. In order to create sustainable community of this town, it is necessary to recover natural environment in the past Ohata having abundant resources of fish and shellfishes. Several measures useful for this are proposed.
