Larvae of the giant spider crab, Macrocheira kaempferi were reared from hatching to the first crab stage in the combination of several conditions, e.g. rearing water (0.5μm filtered with antibiotics, 0.5μm filtered exposed to ultraviolet, offshore seawater, coastal seawater), food (Artemia nauplii, Artemia fed on Phaeodctylum sp.), bottom substrate (with and without coral sand), water temperature (18°C, 18→15°C) . The highest survival rate as obtained in a group in which filtered seawater with antibiotics was used, Artemia nauplii were given, coral sand was placed in the rearing container after megalopa stage, and water temperature was maintained at 18°C during the first zoeal stage and at 15°C after the second zoeal stage. In this group, the best survival to the megalopa and first crab stages were 90% and 67.5%, respectively. The number of bacteria should be maintained lower than 104 CFU/ml to rear the larvae. Suitable conditions tend to decrease and increase the average intermolt periods of zoeal and megalopa stages, respectively.
