Using the measurements of the lower jaw tip to the longest branchiostegal ray (LJBR) and the opercle (LJOP), a discriminant function is presented that will help field observers separate the two species. The function DR-W LJBR (3.31861) LJOP (-2.84856) 6.37198 classified specimens as roundscale spearfish when DR-W was 0 and as white marlin when DR-W 0 with a 95 correct classification rate overall. Since only the head of a specimen needs to be closely observed, the method has particular utility for tournament anglers during the hook removal process.
