Reproductive biology of the hermit crab PaguTUs middendol情 t was studied from August 1992 to January 1994 in Kattoshi, located along the west side of Hakodate Bay, Hokkaido, Japan. Its mating 腿 ason was 仕o m late October to early D ecember with a peak in early November. Ovigerous females were ob. 舵 rved from October to March, with high. est frequencies occu町 ing from Decem. ber to February (mean: 91.3%). Develop. mental stages of incubated eggs were synchronized within the population. Fe. males were found to be able to reproduce in their first year and laying a single clutch each following year. Incubation period was about 3.5 months. W hile ovi. gerous females did not molt from Novem. ber to March, male molting frequency W 8.S also low during the female incuba. tion period. T he covariation of male and female molt frequencies suggests that fe・ l Lales do not necessarily have a growth disadvantage due to molt cessation dur. ing incubation.
