Abstract:A study of the trophic biology of 87 blue marlin caught in
Hawaiian waters indicates that these opportunistic predators consume a diverse
array of prey. The data suggest that the diet of blue marlin is influenced by the
locality of capture. Thus, surface (troll)-caught blue marlin from near the
Hawaiian Islands consume numerous larvae, postlarvae, and juveniles of inshore
species, prey relatively rare in marlin taken on the high seas. Volumetrically,
these inshore forms are of little consequence and probably contribute little to the
energy requirements of blue marlin. As shown in other studies, small tunas are
the single most important component of Hawaiian blue marlin diets.
