Pan-Wen Hsueh (1997) Reproductive output of a minute crab, Baruna sinensis (Decapoda: Brachyura: Ocypodidae: Camptandriinae). Zoological Studies 36(2): 111-114. The reproductive output of a minute ocypodid crab, Baruna sinensis, was examined. A total of 107 ovigerous females was collected from oyster beds at the Kaomei tidal flat, Taichung, Taiwan, in August and September 1994. Size of carapace width (CW) of ovigerous females ranged from 5 to 9 mm. Fecundity varied for each size class, suggesting a possibility of multiple broods at each size class. Size-fecundity relationship sho•.rved a trend of positive allometry but was insignificant in linear regression analysis (F test, p > 0.05). This result probably reflects an irregularity in reproductive output of the crab.

Key words: Size at maturity, Fe undity, Size-fecundity relationship, Baruna sinensis.
