Indian Ocean Tuna Commission. A FAD can either be made of natural materials like bamboo or logs, or synthetic materials that are attached to a buoy. Fish are known to have a tranquil and calming effect on anyone who watches them swim equivocally through the water. By comparing the digestion status of prey with the hour of predator catch by fishermen, it was possible to assess the hypothetical foraging rhythm of the Atlantic bluefin tuna in the Strait of Messina.

It works like a radar system. These mechanisms are: Portland, Oregon: Using satellite information about currents, nutrients in the water, water temperature, and the use of look-outs, helicopters and strong binoculars are used to visually spot tuna schools, and this can only be done during the day.

For sport fishermen, the nature or the development of the heat exchange system in relation to the temperature of the environment at the moment of capture seems to directly influence the combativity of the different tuna species; the bluefin, with its more sophisticated heat exchange system, would always be more combative than a yellowfin or bigeye, for example.

To the paradoxical situation expressed by Kitchell et al.
