Areas of shoaling of "Bonito Listrado" and fishing maps for planned fishing

One of the target resources of rod and live-bait fishing on the Brazilian coast is "Bonito Listrado" (a species of tuna), and success depends on locating the shoals, which are highly migratory. The prediction of locations where shoals are concentrated can be made based on information on the surface temperature of the sea. In spite of the availability of this technology, some fishermen today still use other methods to locate the fish. These include the recording of capture data in the on-board log book.
