the other day I joined tour for obsserving traditional fishing in these area. The fishing is called “大敷網漁” Oshiki Ami ryo. I heard that the fishing is group work and go every morning.
They use very big net to catch up. It starts early morning. Two fishing boat are neccesary and they cooperate with each other.
Finally the net is between two boats and they rolled up.
The result totally depends on the day and it was few on that day. It was really interesting.
