In the rivers of the Paiwan tribe there is always a zone called "laaolan" where it is for bidden to disturb the fish, shrimp and crabs. Lakes along the middle stretches of rivers are also protected zones, and it is only on the tributaries that the people of the tribe are al lowed to fish. "Who would dare to enter the forbidden sections to fish?"
排灣族的溪流總有一段被視為不可干擾的魚、蝦、螃蟹居所，稱為 lalaolan，河流中段有緩潭湖泊，大的水潭也是魚族的堡壘，支流才得以源源補充漁獲，「哪個人敢進水潭取用這些水族？」
