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 ...
A study using sonar in French Polynesia, found large shoals of juvenile bigeye tuna and yellowfin tuna aggregated closest to the devices, at distances of 10 to 50m. Further out, 50 to 150m, a less dense group of larger yellowfin and albacore tuna gathered. Yet further out, to 500m, was a dispersed group of mature tuna.
When fishing from a boat, pretty much any fishing technique can be used, from nets to fish traps, but some form of angling is by far the most common.

Fishing reels are manually cranked reels typically mounted onto a fishing rod, used to wind and stow fishing line [3] when a long casting distance or a prolonged retrieval is expected. Traditional fishing reels are essentially compact windlasses with a " direct-drive " design, while modern reels since the Industrial Revolution typically are ...

This principle requires netting bags which are towed through water to catch different species of fishes or sometimes targeted species.
