Data on egg production cycles for Hippa
pacifica at Enewetak Atoll do not exist.
Wenner (1977) presented egg production data
for the species on the island ofOahu, Hawaii,
indicating that local populations of the crab
may exhibit percentages ofovigerous females
approaching 100 percent. Fusaro (1975)
presented the data for H. pacifica egg production at Enewetak Atoll that are reproduced here in Table 1. These data indicate
that at Enewetak the percentage ofovigerous
females could also approach 100 percent. In
general, though with several exceptions, the
downcurrent (western) islands tended to have
a higher percentage ofovigerous females than
did the upcurrent (eastern) islands (Figure 4,
Table 1). One potential environmental differ
