DRIFTING FISH AGGREGATING DEVICE
natural or artificial free-drifting objects that attract pelagic fishes, such as tunas. Natural ones are logs and branches and objects of human origin such as oil drums and buoys. Artificial ones are deliberately constructed, such as bamboo rafts with purse-seine corks to aid in flotation and strength and with netting hanging down to act both as a drift anchor and as a concealment for smaller fishes. Artificial devices can have a radio or satellite-linked transmitting buoy so it can be located by fishers
