Energy content of Macrobrachium nobilii (Henderson & Mathai) is 0.19 cal in a freshly laid egg, 0.14 cal in a freshly hatched zoea, and 0.09 cal in an 8-day-old non-feeding zoea. These values indicate that the yolk is utilized with an efficiency of 74%, and that yolk equivalent to 0.1 cal is provided in an egg to meet embryonic and larval metabolism. The high yolk utilization efficiency and the high calorific content of the freshly hatched zoeae (5753 cal/g dry wt) are considered as adaptations to larval migration.
