Tongues of flame kill boring worms infesting the bottom of a fishing boat, but do not harm the wooden hull-if the boatman knows his business. He controls burning straw with a bamboo pole, swishing away clumps before the planking ignites. Low tide leaves the boat exposed beside the harbor wall of Shimotsui. To put protein in her diet, Japan sends out nearly half a million fishing vessels, mostly small craft similar to this. Boats ranging no farther than 20 miles offshore produce 70 percent of the national catch. Overlooking nothing edible, fishermen drop clay jars to the bottom to lure octopus. The multi-armed mollusks, loving dark crannies, crawl 314 inside and, never suspecting danger, let themselves be hauled gently to the surface.
