Survival and Growth of Juvenile Sesarmid Crab (Episesarma singaporense) Fed with Different Particle Size of Formulated Diets

Abstract

The impacts of particle size diet to survival and growth of juvenile sesarmid crab (Episesarma singaporense) was investigated by feeding those crabs with different particle size of formulated diets. The results revealed that the survival rate of juvenile crabs fed with large particle size diets (2.8 mm. of diameter) was significantly higher than those fed with small particle size diets; 0.8 mm. and 1.0 mm. (p<0.05). But the growth rate of the juvenile crabs was not significantly influenced by the different dietary particle size (p>0.05). However, the better trend of growth rate was found in the juvenile crabs fed with the large diets (2.0-2.8 mm. diameter). Considering its development duration, the development duration of the juvenile crab was not significantly affected by the different particle size of formulated diets (p>0.05). In summary, the formulated diet with the large size (2.0-2.8 mm. diameter) can be used as a suitable diet to the juvenile of this sesarmid species.
