FADs are traditionally used by fishermen to
attract and aggregate fishes closer to the
shore. Such practices were based on their
knowledge that fish tend to congregate over
submerged structures. These objects are
known to attract fish efficiently and increase
the productivity of the area as they provide
shelter from predators, serves as feeding
grounds by providing surface area for fish
food organisms and even act as suitable
spawning ground by giving substratum for the
attachment of eggs for many fishes
