Lower entanglement risk fish aggregating devices Fish aggregating devices where only small mesh netting is used (< 7 cm stretched mesh) and rafts are tightly wrapped with small mesh netting. The underwater structure is tightly tied into bundles (called “sausages”) so that the risk of…

Highest entanglement risk fish aggregating devices Fish aggregating devices that are constructed with any netting materials, including old large‑mesh purse seine netting, used to cover rafts or suspended beneath in open panels. These FADs are known to cause the highest rate of entanglements with turtles…

Fish aggregating devices Man‑made floating objects specifically designed to encourage fish aggregation at the device. They can be anchored to the ocean floor (anchored FADs) or set to drift in the open ocean (drifting FADs). FADs are widely used as a fishing method due to…

FAD strategy Vessels that largely rely on FADs (floating objects) to catch tunas, primarily skipjack. See also SKJ.

Drifting fish aggregating devices Fish aggregating devices not tethered to the bottom of the ocean. A DFAD typically has a floating structure (such as a bamboo or metal raft with buoyancy provided by buoys, corks, etc.) and a submerged structure (made of old netting, canvass,…

Anchored fish aggregating devices They usually consist of a very large buoy, anchored to the bottom of the ocean with a chain. AFADs are called ‘payaos’ in some regions.
