Distribution and Behavior

A warm-water species, yellowfin is the most tropical species of tuna, and is abundant in tropical waters throughout the Atlantic. Young are known to form large schools near surface. Adults inhabit fairly deep water but also live near the surface.

Yellowfin are often found mixed with other species, especially skipjack and bigeye. Yellowfin are sexually mature when they reach a length of approximately 40 inches, and spawning occurs throughout the year in the core areas of distribution (between 15 N and 15 S latitude), including the Gulf of Mexico, with peaks occurring in summer months.
