Most scombrids (tunas, mackerels, and bonitos) are important food, commercial, and sport fishes. In some parts of the world, i.e. the Mediterranean and Californian coasts, tunas have been fished locally for many years, but heavy commercial exploitation of open-ocean tunas has led in some cases to depletion of tuna populations. Much of the tuna catch is harvested for canning. Apparently the flesh of king mackerel has occasionally been toxic when eaten.
