The trick for making fish fly, as Taiwanese fishermen have known for hundreds of years, is to fish by night. Surrounded only by the darkened seas, fishers light a bamboo stick covered in moistened sulfurized soil to create a blaze so fierce that it drives thousands of sardines into a mad rush to the water's surface. As the fish fling their bodies upwards toward the light, the fishermen ready the nets and ensnare them as they fall. On good nights, catches can bring in $4,500, but that's because there is little competition these days. At its height, 300 fishermen used this technique—known as sulfuric fire fishing—but now only 30 do. To protect this centuries-old tradition, the Taiwanese government has deemed it a "cultural asset" and provides subsidies for those brave enough to fish by fire.
