The greater incidence of the giant trematode, Hirudinella marina Garcin, in skipjack tuna, Euthynnus pelamis (Linnaeus), from Hawaii than in skipjack from the Marquesas led to the hypothesis that this difference in infestation was due to area. Comparisons with respect to sex, size, and time led to the conclusion that a major source of variation could be attributed to time. The available data did not allow a conclusion on whether or not a real difference exists between the two areas.
