Abstract
Caranx caballus Gunther, a wide-ranging tropical eastern Pacific
carangid fish, was reported from the Hawaiian Islands as C. kuhlii (later as C.
kalla) from only two specimens collected in 1922. Because no further specimens
had been collected, these two fish were regarded as strays from the eastern
Pacific; however, beginning in the summer of 1998, this small jack was found
in such numbers in the Hawaiian Islands that it seems to have established a
breeding population. It is distinguished by having 22-24 dorsal soft rays, 1920
anal soft rays, 43-52 scutes, chest fully scaled, 42-46 gill rakers, no large
teeth in jaws, a relatively slender body (depth 3.5-3.75 in fork length), a black
spot on edge of opercle, and no dark bars on the body. Because it is a valuable
food fish, it is expected to be commercially exploited in Hawai'i.
