The globally critically endangered Singapore freshwater crab (Johora singaporensis) is only found in three small streams in Singapore.

Although the technique and expertise to keep this species in captivity for extended periods of time have been developed, successful breeding remain elusive. While some individuals were observed to be gravid on several occasions, the eggs did not hatch.

A population of these crabs are being managed in a captive facility to explore husbandry best practices on how to manage them.

This study will lead to greater understanding of their needs and behaviour. Potential captive breeding success will lead to the establishment of an ex-situ population, which may be necessary to conserve this species in the long run.

This research will shed more light on this highly threatened but poorly known species, and the findings will contribute considerably to its conservation.
