Behavior
Although mainly found in deep offshore waters, yellowfin tuna may approach shore when suitable conditions exist. Mid-ocean islands such as the Hawaiian archipelago, other island groups in the Western Pacific, Caribbean and Maldives islands Indian Ocean, as well as the volcanic islands of the Atlantic such as Ascension Island often harbor yellowfin feeding on the baitfish these spots concentrate close to the shoreline. Yellowfin may venture well inshore of the continental shelf when water temperature and clarity are suitable and food is abundant.
Yellowfin tuna often travel in schools with similarly sized companions. They sometimes school with other tuna species and mixed schools of small yellowfin and skipjack tuna, in particular, are commonplace. They are often associated with various species of dolphins or porpoises, as well as with larger marine creatures such as whales and whale sharks. They also associate with drifting flotsam such as logs and pallets, and sonic tagging indicates that some follow moving vessels. Hawaiian yellowfin associate with anchored fish aggregation devices (FADs) and with certain sections of the 50-fathom curve.

Famous quotes containing the word behavior:
“The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?”
—Leontine Young (20th century)
“Excessive attention, even if it’s negative, is such a powerful “reward” to a child that it actually reinforces the undesirable behavior. You need to learn restraint, to respond to far fewer situations, to ask yourself questions like, “Is this really important?” “Could I let this behavior go?” “What would happen if I just wait?” “Could I lose by doing nothing?””
—Stanley Turecki (20th century)
“Gaining a better understanding of how children’s minds work at different ages will allow you to make more sense of their behaviors. With this understanding come decreased stress and increased pleasure from being a parent. It lessens the frustrations that come from expecting things that a child simply cannot do or from incorrectly interpreting a child’s behavior in adult terms.”
—Lawrence Kutner (20th century)
