Abstract
ENGLISH: The several species of clupeoid fishes used as baitfish in the Eastern Pacific tuna fishery are, in some cases, sufficiently similar to make identification difficult. During a review of the anatomy of the intestine of clupeoid fishes it was observed that the morphology of the intestine is sometimes a useful character in the identification of systematic groups. The genera at least can be distinguished by means of the topographical anatomy of the intestines. This also may be a useful character because it is often found that a species occurs in the same area as another species that may be confused with it on external inspection, although it belongs to a different genus. SPANISH: La gran similitud morfológica de varias especies del órden Clupeoidea usadas como cebo en la pesquería de atún del Pacifíco Oriental, hace que su identificación sea en algunos casos difícil. Al realizar una revisión anatómica del intestino de los peces clupeoides, se observó que la morfología del mismo es a veces un carácter útil para la identificación de los diversos grupos sistemáticos. Al menos los géneros pueden ser distinguidos por medio de la anatomía topográfica de los intestinos. Esto también puede ser un carácter útil, puesto que a menudo dos especies pertenecientes a géneros diferentes y que ocupen la misma área, pueden ser confundidos si nos basamos solamente en la morfología externa.
