The village chief, Sako Uji, lost his boat, his brother and his son in a similar accident. He says poaching by illegal trawlers has cut their catch to less than a quarter.

They patrol the sea, photographing boats fishing too close to the coast. The huge trawlers come from Europe and Japan where stocks are already exhausted.
