## Abstract
Abstract The mortality rate at crablet stage of blue swimmer crab, Portunus pelagicus during weaning is still high. Insufficient in food availability can be a trigger to high cannibalism. On the other hands, the used of artificial feed often causes a decrease in water quality. Information on the use of live feed during the crablet weaning is not yet available. This study aims to look at the opportunity to use Amphipod-crustacea, Grandidierella megnae (Giles, 1888) as a live food at crablet-4 (C4) stage of swimmer crabs. The consumption rate of C4 against amphipod was tested at various density levels using glass containers with 1L volume. Each container was filled with 0.5 L of sterilized sea water with 30 ppt salinity and included one crab of C4. Five levels of amphipod density applied were 5, 10, 15, 20, and 25 ind.L−1 with 10 replications each. The amount of amphipod consumed by a crablet during 10 hours of exposure is recorded and presented in tabular and graphical form. The results showed that the consumption rate of C4 against amphipod increases significantly (P<0.05) as the density of amphipod increase and reach the maximum value at 10 ind.crab−1. Based on the consumption rate of C4 against amphipod, can be concluded that the G. megnae (Giles, 1888) is suitable as a live food during weaning of swimming crab. However, more detail about the effect of amphipod on growth rate of swimming crab is still need more detail study.
