Isolapotamon bauense Ng, 1987 is the largest true freshwater crab in Malaysia and is endemic to the Kuching-Serian region in Sarawak. This crab has been harvested by the Bidayuh community as a supplementary source of protein. Due to their extreme endemism, it has acquired the “Vulnerable” species status in the IUCN Red List of Threatened Species. So far, there is a lack of knowledge regarding many aspects of the reproductive biology of this species. Therefore, study was conducted to determine its egg size and estimating its fecundity. The fecundity of the crab is between 26 and 81 eggs, with the egg diameter ranging between 3.7–4.2 mm, bright orange in colour and attached to the pleopods of the female abdominal brood pouch. It requires extended incubation period approximately 77 days. Information obtained from this study were important to develop propagation techniques destined for wild population restocking programs and for aquaculture.
