Starvation tolerance of the juvenile swimming crab, <I>Poytunus tyituberculatus</I>, was investigated. At water temperatures of 15 to 25°C the survival period (C1) decreased with rearing temperature rising. At water temperatures of 23-24°C the median survival period of crabs (from C1 to C3) was from 9 to 19 days and the starvation tolerance increased with the size of crabs. The point of no return (PNR) for C1 was estimated 8.3 days at 25°C.<BR>The rapid decrease in the number of released artificial seed of the swimming crab in intertidal areas doesn't seem to be caused by starvation.
