Non-fishing oriented conservationists sometimes joke about the FADs, most of which in Hawaii are buoy's but can be a variety of devices. The question is often put, when a vessel is sunk to provide more "fish habitat" or a floating FAD is put in - are these devices actually producing more fish by creating fish habitat, or just creating ways for fishers to harvest dwindling and hard to find fish by creating an attractive space that lures them in. Hence the title, "Fish aggravation or aggregation." The answer depends on the level of use of the FAD and the type. PEWTrusts has a very interesting read on effects of FADs on tuna, see: Fish Aggregation Devices and Tuna, and Hawaii always seems to have some current research on FADs as a matter of course, of which HIMB's Holland lab is often involved through their HIMB Pelagic Fisheries Research unit. They do, as always, excellent work.
