Payao (fishing)
Payaos have been introduced to fishermen in Vietnam, Thailand (where it is known as sung), and various countries in Oceania (including the Federated States of Micronesia, Fiji, Papua New Guinea, and the Solomon Islands).The arong utilizes a vertically-oriented bundle of bamboo with branches imitating roots below-water, and leaves arranged above the surface, mimicking a palm tree.[3] Before World War II anchored and drifting payaos were deployed in all Philippines regional waters barring the east, where strong currents prohibited it.The chronic overfishing of regional Philippine waters, combined with the low impact of shallow-water payao fishing, has led to the establishment of the Tuna Productivity Project in Davao Gulf.[5] Modern payao have cylindrical, bullet-shaped, or rectangular steel floats that can better withstand rough seas, with cement anchors sunk to depths of up to 5,000 m (16,000 ft) deep.
