Mole crab (Hippa adactyla) is a crab species from ordo Decapoda. It lives on sand coastal water sediment that affect by high and low tide. Mole crab also considered as one of important economic species. The aim of this research is to analyze egg productivity, egg diameter, egg volume and production energy of mole crab H. adactyla on sandy beach, Cilacap. The research was conducted from January to December 2013 on sandy beach, Cilacap. The total egg number of H. adactyla is 3 200±2 993 eggs. The average of egg diameter is 0,4409±0,0698 mm and the average of volume is 0,0455±0,0205 mm3. Eggs production by H. adactyla has high correlation with carapace length. The production energy in the form of female dry weight reduction is 0,04%.
