In addition, the stream has been practically fished out, and fishing is no longer permitted there, except during the festival when the ban isn't enforced. They used to hold a fish-catching ceremony before and after the harvest festival, but that died out a few years ago, and so the harvest festival can no longer be said to be preserved whole.
青年人大量外出工作，也使得宜灣溪平日不准捕魚、只有豐年祭才解禁的管制無人執行；在濫捕下，漁產日減，豐年祭前後各舉行一次的「捕魚祭」和「漁撈祭」也在幾年前停辦。宜灣的豐年祭，已不再能被稱作「保存完整」了。
