CGTN's Miro Lu takes you inside a lab in Singapore where dozens of mud crabs are being reared, fed and bred, but in a manner that's clean and sustainable. Dr. Lee Chee Wee, director of the Aquaculture Innovation Centre, will take you on a tour to highlight some of the techniques being used to look after these crustaceans and to create the most optimal feed so they can not only survive but thrive.
